Fall Final Biology Review

Front

What is a substrate?

Back

A substrate is a substance on which an enzyme acts in a biochemical reaction.

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is a double-stranded molecule that contains the genetic instructions for the development and functioning of living organisms. It includes the base Thymine.

Front

What phase of the cell cycle involves cell division?

Back

The M phase (Mitosis) is the phase where cell division occurs.

Front

What phase of the cell cycle involves DNA replication?

Back

The S phase (Synthesis) is the phase where DNA replication occurs.

Front

What is the site of protein synthesis in a cell?

Back

The ribosome is the site of protein synthesis.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for translating messenger RNA (mRNA) into proteins.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions without being consumed in the process.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains Thymine, while RNA is single-stranded and contains Uracil instead of Thymine.

Front

What occurs during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and prepares for DNA replication.

Front

What is the purpose of the G2 phase in the cell cycle?

Back

The G2 phase is where the cell prepares for mitosis, ensuring all DNA is replicated and the cell is ready to divide.
