Are these statements true or false Explain your answers a If

Are these statements true or false? Explain your answers. a) If one of my cells has an error during DNA replication that results in a mutation, this mutation will be passed on to my children. b) DNA damage is the same thing as mutation. c) A DNA sequence change that does not result in a new phenotype can still be called a mutation.

Solution

answers:

a) If one of my cells has an error during DNA replication that results in mutations, this mutation will be passed on to my children ------ TRUE

Explanation: DNA damages are corrected by enzymes, they are not passed to the succeeding generations. Whereas mutation cannot corrected by enzymes. They are passed to succeeding generation, it lead to unwanted protein products and different phenotypes

b) DNA damage is the same thing as mutation.    ------- TRUE

Explanation:

1. DNA damages and mutations are such changes that occur in DNA

2. DNA damages is referred to as breakage or an alternation of the physical and chemical structure of DNA. Mutations is defined as base changes in the DNA sequence.

c) A DNA sequence change that does not result in a new phenotype can still be called a Mutation --- FALSE

Explanation: DNA damages mostly happen during the replication in a newly synthesizing strand. Mutations happen mostly during replication when the wrong template is being selected, and both strands are modified
