Question

conditions for mutation.........3 conditions...........plz ans correctly...​

Answer 1

$\bold \pink{ANSWER}$

• Four classes of mutations are ) spontaneous mutations (molecular decay), nmutations due to error-prone replication bypass of naturally occurring DNA damage (also called error-prone translesion synthesis), errors introduced during DNA repair, and induced mutations caused by mutagens. Scientists may also deliberately introduce mutant sequences through DNA manipulation for the sake of scientific experimentation.
• One 2017 study claimed that 66% of cancer-causing mutations are random, 29% are due to the environment (the studied population spanned 69 countries), and 5% are inherited.
• Humans on average pass 60 new mutations to their children but fathers pass more mutations depending on their age with every year adding two new mutations to a child.!

Answer 2

Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations..
