Biology EOC Review Set 2

Front

What phase of the cell cycle is characterized by DNA replication?

Back

S phase (Synthesis phase) is when DNA is replicated.

Front

What does the near universality of the genetic code suggest about life-forms?

Back

It suggests that all life-forms have a common evolutionary ancestor.

Front

What is the role of RNA in protein synthesis?

Back

RNA carries the code from DNA in the nucleus to the ribosome for protein synthesis.

Front

What happens during anaphase of mitosis?

Back

The chromosomes are pulled apart to opposite poles of the cell.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for 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 cytokinesis?

Back

Cytokinesis is the process where the cytoplasm of a parental cell divides into two daughter cells.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides that corresponds to a specific amino acid.

Front

What is the significance of the ribosome in protein synthesis?

Back

The ribosome is the site where translation occurs, synthesizing proteins from amino acids.

Front

What occurs during metaphase of mitosis?

Back

Chromosomes align at the cell's equatorial plane before being separated.
