Biology SOL Review (Part 1)

Front

What is the process that describes the replication of DNA during cell division?

Back

Replication of DNA occurs during the S phase of interphase.

Front

What structure of the cell membrane regulates the passage of substances into and out of the cell?

Back

The phospholipid bilayer is primarily responsible for regulating the passage of substances.

Front

What is the structure of DNA?

Back

DNA is a double-stranded helix.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes lower the activation energy required for chemical reactions to occur.

Front

What type of mutation is characterized by the insertion or deletion of nucleotides, causing a shift in the reading frame?

Back

Frameshift mutation.

Front

What is interphase in the cell cycle?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What are integral membrane proteins?

Back

Integral membrane proteins are proteins that span the entire membrane and are involved in transporting substances across the membrane.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's fluidity.

Front

What is a missense mutation?

Back

A missense mutation is a change in a single nucleotide that results in a different amino acid being incorporated into a protein.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a change in a nucleotide that creates a premature stop codon in the protein sequence.
