Cell Cycle

Front

What is Cell Theory?

Back

Cell Theory states that: 1) All organisms are made of one or more cells, 2) The cell is the most basic unit of life, 3) All existing cells are produced by other living cells.

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase adds nucleotides to the growing strand of DNA based on complementary base pairing.

Front

What are cyclins?

Back

Cyclins are proteins that regulate the progression of the cell cycle by activating Cyclin Dependent Kinases (CDKs).

Front

What does semi-conservative DNA replication mean?

Back

Semi-conservative DNA replication means that each new DNA molecule consists of one parental strand and one newly synthesized strand.

Front

What are Cyclin Dependent Kinases (CDKs)?

Back

CDKs are proteins that, when activated by cyclins, control the progression of the cell cycle.

Front

What is the function of DNA Primase?

Back

DNA Primase synthesizes a short RNA primer to initiate DNA replication.

Front

What is the function of DNA Helicase?

Back

DNA Helicase unwinds the DNA double helix during replication.

Front

What is the G1 phase of the cell cycle?

Back

The G1 phase is the first gap phase where the cell grows and prepares for DNA synthesis.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

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

Back

The M phase is where mitosis occurs, leading to the division of the cell into two daughter cells.
