Genetics Flashcard 1 - DNA, Replication, and Cell Cycle and Division

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

Which strand is known as the lagging strand in DNA replication?

Back

The lagging strand is depicted by letter B.

Front

What is the correct order of DNA replication?

Back

3, 4, 1, 2.

Front

What stage of the cell cycle is characterized by the separation of chromosomes?

Back

Telophase.

Front

In which phase does the cell spend most of its life?

Back

Interphase.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

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.

Front

What is the function of the cell cycle checkpoints?

Back

Cell cycle checkpoints ensure that the cell is ready to proceed to the next phase, preventing errors.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs during the S phase.
