If you ask "what is a genome", I'm afraid it's better, because you understand what a genome is, and your question is not a problem. Humans have only one genome, about 5-100,000 genes. The human genome has two meanings first:
One is all the genetic information that represents all of us as a human being as a whole, but each with its own differences; The second is the DNA molecules that are present in all the cells of each of our human bodies, and they are all nearly identical. The genome of a species has four meanings: it represents the sum of all our genetic information
The sum of 23 (haploid) chromosomes, the sum of 23 DNA molecules, the sum of our genes. As with the human genome, the DNA involved in the life activities of bacteria, beans and all the genes that determine them are called the genomes of bacteria and beans. The DNA included in the genome is called "genomic DNA".

Listen up, little ghost.
Chromatin = chromosomes (morphologically distinct).
Chromosomes include DNA, proteins.
DNA is composed of deoxyribose + phosphoric acid + N-containing bases.
A gene is a genetic trait (a piece of DNA that can express genetic information), and the genome is the sum of genes, several valid fragments of genes on all chromosomes.
-
The composition of genes is the sum of the genetic information carried by an organism.
A gene is a kind of genetic material arranged on chromosomes, which is the smallest functional unit of biological genetic material, and each gene carries the information of a certain characteristic of an organism. A wide variety of genes have their own specific positions on chromosomes, each gene is made up of many nucleotides in a different order, genes control the process of protein manufacturing, and different genes only act on different proteins.
Genetic computation
DNA molecules are similar to "computer disks", which have functions such as saving, copying, and rewriting information. Straightening the molecules of the spiral DNA would be longer than a person's height, but if folded, they could shrink into small balls with a diameter of only a few microns. Therefore, DNA molecules are regarded as ultra-high-density, large-capacity molecular memory.
Gene chips have been improved to express different numbers in different biological states and can also be used to make biocomputers. Based on gene chips and gene algorithms, the future bioinformatics field is expected to be comparable to today's computer hardware giants Intel and software giants Microsoft.

The basic building block of genes: deoxyribonucleotides. Deoxyribonucleic acid (DNA) is a polymeric compound that is the genetic material of all living organisms except RNA viruses.

The genome is the sum of all the genetic material of an organism. A genome contains a complete set of genes.
In the field of molecular biology and genetics, genome refers to the sum of all the genetic material of an organism. This genetic material includes DNA or RNA (viral RNA). Genomic DNA includes coding DNA and non-coding DNA, mitochondrial DNA, and chloroplast DNA.
The term genome was coined in 1920 by Hans Winkler, a professor of botany at the University of Hamburg in Germany.
In a typical diploid cell or individual, the lowest set of chromosomes that can maintain the normal function of gametes or gametophytes is called a chromosome set or genome, and a genome contains a complete set of genes. All the corresponding cytoplasmic genes constitute a cytoplasmic genome, which includes mitochondrial genome and chloroplast genome.

A gene is a piece of DNA that has a genetic effect.
DNA and proteins make up chromosomes.
So there are many genes on one chromosome.
Genome. It is the intracellular gene composition. In general, animals are diploid organisms, so each gene does not exist individually, but in pairs. The way genes that exist in pairs are combined is called the genome.
-
The genome is the entire DNA information in a cell of an organism.
These DNA are interrupted, attached to a vector and transferred to microorganisms so that these microbial cells contain the entire genome of an organism. These microorganisms then make up the genome library.
Both of the above contain genetic information. The genetic information of any cell is the same for a certain organism.
cDNA is obtained by reverse transcription of intracellular mRNA, which contains an intracellular expression information. The expression information of different cells in multicellular organisms is often different. If all of the mRNA (also known as the cell's transcriptome) of a cell is reverse transcribed into cDNA, and then these cDNA are attached to a vector (basically uninterrupted) and transferred into microorganisms, then these microorganisms form a cDNA library.
In simple terms, genomes are molecules, genomic libraries are microorganisms that represent genetic information, and cDNA libraries are microorganisms that represent information.

To put it simply, a genome is a collection of all the genes of a species.
Genome refers to a complete set of haploid sequences carried by a cell or organism, including a complete set of genes and spacer sequences. However, genome sequencing results show that the gene coding sequence accounts for only a small part of the entire genome sequence. Therefore, the genome should refer to the entire DNA molecule in a haploid cell, including coding and non-coding sequences.
To be more precise, the nuclear genome is the entirety within the nucleus of a haploid cell.
DNA molecules; The mitochondrial genome is the entire DNA molecule that a mitochondria contains; The chloroplast genome is the entire DNA molecule contained in a chloroplast.
-
A gene is an ordered sequence of nucleotides that encodes a corresponding product to perform a corresponding function; Genome rent tolerance is a collection of all genes of a particular species.
A gene is the basic unit of heredity, a specific nucleotide sequence on a DNA or RNA molecule that has genetic information, that is, a gene is a nucleotide sequence encoding a specific protein or multiple proteins, and its information carrier may be DNA or RNA.
The genome, i.e., an individual of a species of Wuchang is developed from a fertilized egg, which contains all the necessary information for the development of an individual of all the species, which is composed of all genes and non-coding sequences.
The structure of plant mitochondrial genomes varies greatly, but mitochondrial genes are extremely conserved, which is the most conservative and slowest evolution rate among the three sets of plant genomes. Cucumbers have such a large mitochondrial genome, but there are only four more genes than Arabidopsis. It is precisely because the mitochondrial genes in plants are very conserved and the discrimination is insufficient, so they are generally not selected as molecular markers for systematics research. >>>More

DNA Repair Essence sounds weird and awkward. DNA is deoxyribonucleotide, we all know that the human body is made up of cells, when cells multiply, DNA will be divided into two, forming two single strands, and then from these two single strands each form a complete DNA The two DNA are the same. DNA is genetic material, it has a specific structure, and if this structure changes, is there any mechanism to restore it to normal? >>>More
The use of scientific means to extract the required genes from a certain organism, transfer them into another organism, and recombine them with the genes of another organism to produce specific substances with excellent genetic traits. Genetically modified technology can be used to breed new varieties and other things. >>>More
