Meiosis continually reshuffles the genes resulting in a great variety of offspring. Without meiosis we would all look exactly alike. Meiosis allows each offspring to be different, and so potentially better, than the parent. If a disease comes along, there is a good chance that some of the population won't get sick or die because everyone's DNA isn't exactly alike.
Prokaryotes DNA is much smaller than eukaryote DNA
Answer:
Mitosis creates diploid cells, while gametes (sperm and oocytes) are haploid cells
Explanation:
Mitosis is the process by which somatic (non-germ line) cells replicate, and two identical cells, called daughter cells are produced from each division. These cells are diploid, meaning that the cell has paired chromosomes. Meiosis is the process by which gametes, sperm cells and oocytes, are produced and these cells must be haploid, or contain unpaired chromosomes, so that when fertilization occurs, the chromosomes from the sperm cells and the chromosomes from the oocytes can recombine to create unique pairs of chromosomes for the resulting zygote. Thus, mitosis will never be able to create germ cells as germ cells must be haploid.
Mechanisms of gene regulation include: Regulating the rate of transcription. ... Regulating the processing of RNA molecules, including alternative splicing to produce more than one protein product from a single gene. Regulating the stability of mRNA molecules.
