In which part of the cell does DNA replicate?
(a)
During which particular phase does DNA replicate?
(a)
3. It is the name of the sugar in DNA.
(a)
This enzyme is responsible for adding nucleotides to the two separated DNA strands.
(a)
The DNA strands are twisted around each other, and that’s why a DNA molecule is a (a) .
A DNA sequence is a chain of (a) .
A (a) is always paired with cytosine, and there are three hydrogen bonds between them.
The helicase continuously unzips the DNA molecule, and the (a) continuously adds nucleotides to each of the separated strands.
. When the process of unzipping DNA molecules and adding nucleotides is finished, there will be two unidentical (a) molecules produced.
