DNA & Cell Cycle Flashcardizz

Front

What are the components of the DNA backbone?

Back

The backbone of the DNA strand is made of phosphate and sugar.

Front

During which phase of the cell cycle is DNA replicated?

Back

DNA is replicated during the Synthesis (S phase) of the cell cycle.

Front

What is the result of cells going through mitosis repeatedly without entering interphase?

Back

This results in cancer.

Front

Which base does Guanine bond with in DNA?

Back

Guanine bonds with Cytosine.

Front

Which base does Adenine bond with in DNA?

Back

Adenine bonds with Thymine.

Front

What is the structure of DNA commonly described as?

Back

DNA is commonly described as a double helix.

Front

What are the four nitrogenous bases found in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand.

Front

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

Back

The S phase is significant because it is the phase where DNA replication occurs, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between mitosis and meiosis?

Back

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