DNA translation produces water not? Is there water produced during translation in gene expression?

I just looked at the second floor, and I still insist that the synthesis of biological macromolecules should be dehydrated, for the following reasons.

1 I learned this way when I was in college, 2 I read the K12 forum, I think the author didn't figure out who combined with whom, his phosphate formula undercounted one hydrogen atom, and the corresponding condensation position was also wrong, so I came to such a strange conclusion that the formation of DNA 3-5 diphosphate must have OH and H dehydration, and it is dehydration of two (3 a, 5 a) This point is almost not controversial, 3 As far as the molecular formula written by the author is concerned, the analysis is crooked, The author said that the formation of RNA is similar to DNA, I agree, in addition, one of the raw materials for DNA synthesis is ATP, this is also very clear, ATP, CTP GTP TTP are all related raw materials, and they all have to interrupt the high-energy health, because the synthesis requires energy, the author did not write about the water released by the chemical reaction, only wrote the released phosphoric acid. That is the original author in order to emphasize that the synthesis process needs energy, so water is ignored, and the general biological reaction equation does not pay much attention to the change of water, which is also an industry habit, because few people isotope track water, all biochemical reactions are carried out in the water environment, water is very important, but as a research object, it is of little value, the focus of biochemical reaction research is still the change of biological organic macromolecules, with the exception of individual reactions such as Hill reaction.

And finally: as far as exams are concerned, it is undoubtedly true that the formation of biomacromolecules requires dehydration. It's not a subjective assumption, and the translation is protein synthesis, how can it not be dehydrated, in the same way, transcription is the formation of RNA macromolecules, also dehydration, and a few more words, the formation of polysaccharides is also formed by the dehydration of monosaccharides.

The combination of the base and the five-carbon sugar is also dehydrated (this can be referred to the teacher's reference book of the Human Education Society).

The author's spirit of daring to doubt is good! But I'm very opposed to giving children the wrong view, things that I can't get accurate, don't draw conclusions to students, and can't pursue words that are not amazing and endless.

Translation is the process of RNA-guided peptide chain synthesis, and peptide bonds are formed between amino acids and amino acids, and of course water must be removed.

The site of translation is ribosomes, which are organelles that produce water, and here's why.

The three processes of DNA replication, transcription, and translation are all produced without water.

The following ** has detailed information o( o

DNA is genes, and without the water molecule H2O in it, it is impossible to produce water.

The process of translation in gene expression is produced by water, which is analyzed as follows:

1. The chemical essence of translation is the dehydration and condensation of a single amino acid to form a peptide chain, a process that requires the participation of a variety of enzymes;

2. Many reactions in biochemistry to form biological macromolecules are formed by the formation of water condensation, taking the formation of the most common protein as an example: the carboxyl group of an amino acid molecule, that is, -COOH, is connected with the amino group of another amino acid molecule, that is, -NH2, and at the same time loses a molecule of water, this combination is called dehydration condensation.

To sum up, it can be seen that the formation of peptide bonds in the peptide chain during the translation process requires the removal of a -OH hydroxyl group and the removal of a -h amino group, and the combination of the two to remove a water molecule, so it is produced by water.

There is a process of DNA replication and RNA reverse transcription of DNA DNA transcription and RNA replication have a process of ribonucleotide polymerization The basic units of DNA and RNA are connected by phosphodiester bonds The connection of the basic units is a phosphate group, a free carboxyl group and a free hydroxyl group are dehydrated to form an ester group and organic chemistry.

The formation of peptide bonds in the peptide chain during the translation process requires the removal of a -OH hydroxyl group and a -h removal of the amino group, and the two combine to remove a water molecule, so it is produced by water.

Gene expression products are usually proteins, but the expression products of non-protein-coding genes such as transfer RNA (tRNA) or small nuclear RNA (snRNA) genes are functional RNAs.

Yes During the synthesis of peptide chains, amino acid dehydration and condensation Two molecules of amino acids are stripped of 1 molecule of water to form a peptide bond.

However, the synthesis of peptide bonds requires the consumption of ATP, and ATP water release energy also requires 1 molecule of water, so the generated water and the required water are exactly offset.

Not really. Shouldn't the product be a protein or a polypeptide chain?

Some. Taking DNA replication as an example, one strand is used as a template to synthesize another strand during replication. The synthesized chain is to continuously add free dNTP to the short single strand, and esterification occurs in the process.

The phosphoric acid molecule is dehydrogenated, and the five-carbon sugar removes the hydroxyl group to form phosphodiester bonds to form water.

To produce water, the nucleotides are dehydrated and condensed to obtain a nucleotide chain.

DNA replication is a semi-reserved double-helix replication.

Untwist while copying. DNA helicase is needed to unwind, because energy is needed to break the bonds. When replicating, it needs to bind to free deoxynucleotides, and the binding site is a phosphodiester bond, which needs to form a bond and requires energy.

The formation of phosphodiester bonds should require the formation of water. (The cleavage of phosphodiester bonds is called hydrolysis, although the generation is not called dehydration condensation?) ）

Yes, it is provided by the mitochondria.

I kind of don't remember! Wait for me to flip through the books I used to have!

The process of DNA replication and transcription produces phosphodiester bonds, which remove a molecule of water.

1. DNA is deoxyribonucleic acid (abbreviation of deoxyribonucleic acid in English), also known as deoxyribonucleotide, which is the main component of chromosomes and the main genetic material.

2. Sometimes referred to as "genetic particles", because during reproduction, the parents copy half of their own DNA and pass it on to the offspring, thus completing the transmission of traits. The chromosome of a prokaryotic cell is a long DNA molecule. There is more than one chromosome in the nucleus of a eukaryotic cell, and each chromatid also contains only one DNA molecule.

3. However, they are generally larger than the DNA molecules in prokaryotic cells and are bound to proteins. The function of the DNA molecule is to store the entire genetic information of almost all proteins and RNA molecules that determine the traits of a species; Encoding and designing biological organisms to transcribe genes and express proteins in a certain time and space in an orderly manner, complete all the programs of directed development; The unique traits and personalities of the organism and all the stress responses when interacting with the environment are preliminarily determined. In addition to chromosomal DNA, a very small amount of structurally different DNA is present in the mitochondria and chloroplasts of eukaryotic cells.

The genetic material of a DNA virus is also DNA, and very rarely RNA.

4. Diversity Due to the different number of base pairs, the order of base pairs is ever-changing, which constitutes the diversity of DNA molecules. For example, a DNA molecule with 4,000 base pairs carries 4 types of genetic information, or 10 types.

5. Specificity Different DNA molecules have differences in the order of base pairs, therefore, the base pairs of each DNA molecule have their specific order of arrangement, which contains specific genetic information, so that the DNA molecule has specificity.

Translation: Ribosomes, mitochondria, and places where there is aerobic respiration can produce water.

The result of gene expression is the synthesis of proteins, and the dehydration and condensation of amino acids during protein synthesis will produce water, which is more obvious.

The transcription process synthesizes mRNA, which is made by the polymerization of ribonucleotides, and dehydration also occurs during the polymerization process, forming phosphodiester bonds.

Gene expression includes transcription and translation, the generation of unprocessed proteins, and the dehydration and condensation of amino acids during translation. The rest is not very clear.
