Anonymous users2024-02-10I think you're asking if DNA has a molecular formula.
The answer is: no.
DNA belongs to macromolecular substances, it is a general term for biomolecules with a certain structure and function, of course, a specific DNA molecule of a certain organism can write a molecular formula and structural formula. Because we can know how many g, c, a, t. there are in this DNA moleculeSo the molecular formula is determinable.
This is equivalent to asking if a protein has a chemical formula. Protein is just a full name, and only a certain protein has a chemical formula.

Anonymous users2024-02-08Because everyone's DNA is not the same, then every individual organism carries a different substance (if the molecules are not the same, it does not acid the same substance), then there are not more than 20 million kinds of organic matter found now, but trillions of them'

Anonymous users2024-02-07DNA is a macromolecular substance, and if you want to write it down, you can write it, but the DNA of an organism needs to be written on tens of thousands of pages.
In general, only the DNA base sequence that encodes a specific protein is written.
For example: atgcatgcatgc But if you want to write more completely, you have to give one point.
Tacgtacgtacg is also written as a 5-carbon sugar (ribose) and a molecule of phosphoric acid. Come out.

I don't know what to do with you.

Anonymous users2024-02-05DNA (abbreviated for deoxyribonucleicacid), also known as deoxyribonucleic acid, is the main chemical component of chromosomes and is also the material that makes up genes. Sometimes referred to as "genetic microparticles" because during reproduction, the parents copy and pass a portion of their own DNA to the offspring, thus completing the transmission of the trait. The nucleoid of a prokaryotic cell is a long DNA molecule.
There is more than one chromosome in the nucleus of a eukaryotic cell, and each chromosome contains one or two pieces of DNA. However, they are generally larger than the DNA molecules in prokaryotic cells and bind 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

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.

Anonymous users2024-02-02According to the principle of base complementarity, the number of a on one chain is equal to t on another chain, and t=a, c=g, g=c, bring the above formula into a+t c+g=2, a+t c+g=2=t+ag+c; So a+t c+g=2.
In the same way, c+a g+t=2=g+t c+a, i.e., g+t c+a=2 of the other chain, so c+a g+t=1 2
DNA is a long-chain polymer with a unit called a deoxynucleotide, while sugars are linked to phosphate molecules by ester bonds to form their long-chain backbone. Each sugar molecule is connected to one of the four bases, which are arranged along the long DNA chain to form the genetic code, which is the basis for the synthesis of protein amino acid sequences. The process of reading a code, called transcription, is the process of making a copy of a nucleic acid molecule called RNA based on the DNA sequence. >>>More
Wrong. Both DNA and RNA can carry genetic information and can be used as genetic material. But when DNA and RNA exist at the same time (as long as there is a cellular structure and most viruses), only DNA is genetic material. >>>More
Chloroplasts are semi-autonomously inherited organelles! The DNA in chloroplasts can control the synthesis of small parts of proteins that they need; Most of the rest of the proteins are synthesized by nuclear DNA, which is then transported into chloroplasts!

There are many discoveries, but the most amazing and interesting thing is that I found that the fish is sleeping with their eyes open. >>>More
