A base substitution mutation within a coding region of DNA always results in a n

Question

A base substitution mutation within a coding region of DNA always results in a new amino acid sequence.

Question 1 options:

B:False

The DNA strand that is synthesized continuously is called the lagging strand.

Question 6 options:

Question 7 (1 point)

The DNA strand that is synthesized discontinuously is called the leading strand.

Question 7 options:

Question 8 (1 point)

DNA ligase joins adjacent Okazaki fragments together into a complete strand.

Question 8 options:

Question 9 (1 point)

DNA polymerases cannot initiate synthesis of a new DNA strand; they can only add bases to an existing strand.

Question 9 options:

Question 10 (1 point)

DNA polymerase I removes the RNA primer and synthesizes a short sequence of DNA that will base pair with the parent strand of DNA.

Question 10 options:

A:True

B:False

The DNA strand that is synthesized continuously is called the lagging strand.

Explanation / Answer

Answer:

1). B. False

Base substitution may or may not result in new amino acid always, because some of the amino acids have more than one codons.

6). B. False

The DNA strand that is synthesized continuously is called the leading strand

7). B. False

The DNA strand that is synthesized discontinuously is called the lagging strand

8). A. True

Ligase enzyme joins the fragments of DNA, hence it is called stiching enzyme.

9). A. True

10). A. True

The unique 5 3 exonuclease activity of DNA polymerase I removes the RNA primer at the beginning of each Okazaki fragment.
