ASHS PreAP & Reg Biology - DNA & Cell cycle Review

Front

What sugar is found in DNA?

Back

Deoxyribose

Front

What happens to chromosomes before cell division?

Back

They are replicated, consisting of 2 copies of 1 chromosome, and are ready to go through the M phase.

Front

What is the shape of DNA?

Back

Double helix

Front

What must be copied before cells can divide?

Back

DNA

Front

What is the process of making a copy of DNA called?

Back

DNA replication

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of DNA polymerase?

Back

It is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain during DNA replication.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is single-stranded.

Front

What is the function of the cell cycle?

Back

To regulate cell growth, DNA replication, and cell division.
