Answer:
cell division
Explanation:
It starts with a cell called the mother cell, divides into two cells called daughter cells. If they have the same number of chromosomes it is called mitosis. As in there are two different stages of cell division. Where as meiosis, they don't have the same amount of chromosomes.
Answer:
Explanation:
When a substance has the capacity to disrupts the genetic compositions (DNA) of the organisms, to the extent that it makes the particular organism genetic materials prone to genetic mutation,( random changes in the genetic composition) such group of substances are called Mutagens.
ionizing radiation,radioactive decay are some examples of of physical mutagens, while biological mutagens examples include viruses and bacterial. Chemical mutagens are Benzene compounds,bromine,aromatic amines,sodium Azide.
They exerts their negative effects
by disrupting gene expression sequence of transcription, translation, or changed the nucleotides sequence of the DNA leading to deletion, addition, subtraction of genetic bases.Some may make chromosomes to be unstable, disrupting the structure
Although some mutagens can cause cancer, that is they are mutagens. not all mutagens carcinogenic.This is because the Mutagenic effects depends on the metabolites present in the cells of the organisms.
<span>DNA is responsible for passing information for making protiens. DNA is linked with chromosomes, which are duplicated in every cell of the organism's body. Depending on the mode of reproduction, it either undergoes meiosis to produce haploid gametes, which are fertilized and become diploid, and hopefully mature to become reproductive adults or undergoes mitosis to form a fully-fledged adult which eventually drops off the parent and goes on to produce other adults</span>
