DNA, Replication, and the Cell Cycle Practice Questions Period 5

Front

What is the process of DNA replication that involves reusing the old DNA strand called?

Back

Semi-Conservative

Front

What are the monomers that make up DNA?

Back

Nucleotides

Front

Which enzyme is responsible for building complementary DNA strands during replication?

Back

DNA Polymerase

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds

Front

What is the shape of DNA?

Back

Double helix

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine, Thymine, Cytosine, Guanine

Front

What is the role of DNA Ligase in DNA replication?

Back

To join Okazaki fragments on the lagging strand.

Front

What is the function of Primase in DNA replication?

Back

To synthesize a short RNA primer for DNA polymerase to start replication.

Front

What is the difference between the leading strand and the lagging strand during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments.

Front

What is the significance of the semi-conservative nature of DNA replication?

Back

It ensures that each new DNA molecule contains one old strand and one new strand, preserving genetic information.
