What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through from its formation until it divides into two daughter cells. It includes phases such as interphase (G1, S, G2) and mitosis.

What is transcription?

Back

Transcription is the process of making RNA from a DNA template, where the DNA sequence is copied into a complementary RNA sequence.

Front

What is a phenotype?

Back

A phenotype is the physical appearance or observable characteristics of an organism, determined by its genotype and environmental influences.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are interphase (which includes G1, S, and G2 phases) and mitotic phase (which includes mitosis and cytokinesis).

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and carries out normal metabolic processes, preparing for DNA replication.

Front

What happens during the S phase of the cell cycle?

Back

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

What is the role of RNA in the cell?

Back

RNA plays several roles in the cell, including serving as a template for protein synthesis (mRNA), forming the structure of ribosomes (rRNA), and transferring amino acids to ribosomes (tRNA).

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics of that organism.
