Front

What phase of the cell cycle is responsible for cell growth?

Back

G1 phase

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, nitrogen base.

Front

What is the result of mitosis?

Back

Mitosis results in identical daughter cells.

Front

Which two bases are classified as pyrimidines?

Back

Cytosine and thymine.

Front

What is the function of DNA?

Back

DNA stores and transmits genetic information.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, thymine, cytosine, and guanine.

Front

What is the role of the S phase in the cell cycle?

Back

The S phase is where DNA replication occurs.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical cells, while meiosis results in four genetically diverse cells.

Front

What is cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells.
