Cell Cycle, DNA Structure, Replication & Protein Synthesis

Front

What is the function of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from the DNA in the nucleus to the ribosome, where proteins are synthesized.

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that wind around each other.

Front

What are the three components of a nucleotide?

Back

A nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

Where does translation occur in the cell?

Back

Translation occurs at the ribosome, where mRNA is translated into a protein.

Front

What is the role of the nucleus in the cell cycle?

Back

The nucleus houses the cell's DNA and is the site where transcription occurs, producing mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is the purpose of DNA replication?

Back

DNA replication ensures that each daughter cell receives an exact copy of the parent cell's DNA during cell division.

Front

What are the stages of the cell cycle?

Back

The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

Front

What is the significance of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.
