Detailed explanation-1: -Mutagens can alter the DNA structure and cause mutations in the DNA. Deleterious mutation can cause aberrant, impaired or loss of function for a particular gene.
Detailed explanation-2: -Anything that causes a mutation (a change in the DNA of a cell). DNA changes caused by mutagens may harm cells and cause certain diseases, such as cancer. Examples of mutagens include radioactive substances, x-rays, ultraviolet radiation, and certain chemicals.
Detailed explanation-3: -Mutagenesis is a technique used in molecular biology to create mutant genes, proteins, and organisms. Two primary mutagenesis techniques are site-directed mutagenesis (SDM) and random-and-extensive mutagenesis (REM).
Detailed explanation-4: -Mutations are changes that occur in DNA or RNA. Mutations can be silent, meaning they have no effect on the protein made, due to redundancy in the genetic code.
Detailed explanation-5: -These agents are known as mutagens, and they act by directly altering a cell’s DNA sequence. Many mutagens, by virtue of their size or structure, can slip through both cell and nuclear membranes and interact with DNA directly, usually resulting in damage.
