Biology EOC Review Set 2

Front

What phase of the cell cycle is DNA replicated?

Back

During the S phase.

Front

What is the process of copying DNA into RNA called?

Back

Transcription.

Front

Which type of RNA carries the genetic information from DNA to the ribosome?

Back

Messenger RNA (mRNA).

Front

What do all living organisms share in terms of genetics?

Back

Universal genetic code.

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

tRNA brings amino acids to the ribosome during translation.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the site of protein synthesis.

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.

Front

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

Back

The G1 phase is where the cell grows and prepares for DNA replication.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein function.

Front

What is the role of enzymes in biological processes?

Back

Enzymes act as catalysts to speed up chemical reactions.
