Multiple Choice

During what part of the cell cycle does DNA replication occur?

• prophase

• cytokinesis

• interphase

• telophase

Multiple Choice

What is the result of DNA replication?

• Two identical DNA molecules are produced.
• No DNA molecules are produced.
• Two different DNA molecules are produced.
• One DNA molecule is produced.

Multiple Choice

Why is DNA replication considered semi-conservative?

• DNA replication is conservative because both strands are new.
• because each new DNA molecule contains one original strand and one new strand

• because each new DNA molecule contains two original strands.

• DNA replication is semi-conservative due to the use of RNA primers and DNA polymerase

Open Ended

What is the first step of protein synthesis?

Multiple Choice

How is RNA different from DNA?

• RNA is double-stranded, and uses thymine instead of uracil.

• RNA is single-stranded, and uses adenine instead of uracil.

• RNA is double-stranded, and uses cytosine instead of thymine.

• RNA is single-stranded, and uses uracil instead of thymine.

Multiple Choice

What is transcription?

• turning a single strand of RNA into a double strand of DNA

• turning a double strand of DNA into a single strand of RNA

Open Ended

After DNA is transcribed into RNA, what is the next step in protein synthesis?

Multiple Choice

What is translation?

• Turning a single strand of RNA into a chain of amino acids

• turning a double strand of DNA into a single strand of RNA

• turning a double strand of DNA into a strand of amino acids

Multiple Choice
