What are mutations?


repairs of damage to ​ DNA ​ molecules by specialized enzymes

removal of damaged ​ DNA ​ nucleotides by enzyme molecules

reduction in the rate of replication of ​ DNA ​ due to regulatory mechanisms

changes in nucleotides of a ​ DNA ​ molecule that affect the genetic message

Answer 1

Answer:

Mutations are alterations to a DNA sequence. If one thinks of the information in DNA as a series of sentences, mutations are errors in spelling the words that make up those sentences. Sometimes mutations are inconsequential, like a misspelled word whose meaning is still quite clear. At other times mutations have stronger ramifications, like a sentence whose meaning is completely changed.

Answer 2

Answer:

The answer is option 4.

Explanation:

Mutation is the changes in nucleotides of a DNA molecule that affect the genetic message.

For example, in a ordinary DNA, base sequence will be, A pairing with T and C pairing with G.

But in the DNA of mutation, base sequence would be mess up like A pairing with C or G and T pairing with G or C which causing them to be mutant.
