What is the base pairing rule in DNA?

Back

In a double-stranded DNA molecule, Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C).

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm of a parental cell is divided into two daughter cells.

Front

During which phase of the cell cycle does chromatin condense into chromosomes?

Back

Chromatin condenses into chromosomes during Prophase.

Front

What does it mean for DNA strands to be antiparallel?

Back

Antiparallel means that the two strands of DNA run in opposite directions; one strand runs 5' to 3' and the other runs 3' to 5'.

Front

What is the primary purpose of the cell cycle?

Back

The primary purpose of the cell cycle is to create new daughter cells.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are Interphase (G1, S, G2) and Mitosis (Prophase, Metaphase, Anaphase, Telophase).

Front

What occurs during the S phase of Interphase?

Back

During the S phase of Interphase, DNA replication occurs, resulting in two identical sets of chromosomes.

Front

What is the role of mitosis in the cell cycle?

Back

Mitosis is the process of nuclear division that results in two identical daughter nuclei.

Front

What is the difference between mitosis and meiosis?

Back

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

Front

What is the significance of the G1 checkpoint in the cell cycle?

Back

The G1 checkpoint ensures that the cell is ready for DNA synthesis, checking for DNA damage and adequate cell size.
