Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation. Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines. Through transcription the sequence of bases of the DNA are transcribed into the reciprocal sequence of bases in a strand of RNA. Through transcription the information of the DNA molecule is passed onto the new strand of RNA which can then carry the information to where proteins are produced. RNA molecules used for this purpose are known as messenger RNA (mRNA). A gene is a particular segment of DNA. The sequence of bases in for a gene determines the sequence of nucleotides along an RNA molecule. Only one strand of a DNA double helix is transcribed for each gene. This strand is known as the ‘template strand’. The same template strand of DNA is used every time that particular gene is transcribed. The opposite strand of the DNA double helix may be transcribed for other genes. During translation, the information of the strand of RNA is ‘translated’ from RNA language into polypeptide language i.e. the sequence of nucleotides is translated into a sequence of amino acids.
A lot of informations but I hope this helps ;)

Answer:
Genetic drift is simply a change in the frequency of alleles in a population.
Like shown in the comic A, there are different genes present on chromosomes. All of these genes are made up of a pair of alleles. These alleles determine the genotype and the resulting phenotype of an organism.
If none of the alleles is favored by the environment, then a population will have equal no.of all the variant forms of a trait. Like shown in the comic B, both the green and the grey animals are favored equally.
But if natural selection occurs and one form of the allele variant is favored, then a genetic drift will occur. Most of the organisms will have the alleles which are favored by the environment. Like shown in Comic C, where the grey alleles are favored more than the green alleles.
Answer:
A. The number of genes on its chromosomes
Explanation:
The reason why genes are so important is because genes can be transcribed to make mRNAs, and mRNAs can then be translated to make proteins. Proteins are an integral part of life, since they regulate so many processes and functions. Therefore, the number of genes (or lack thereof) in an organism defines how the organism is going to function.
This is mitosis: the cell does steps before it splits in two
G1 - synthesis - G2 - M(mitosis) in mitosis is PMAT
Prophase
Metaphase
Anaphase
Telophase
Then the last step is cell division or what its called is cytokinesis
