Multiple Select

The difference between DNA and RNA is that: (choose all that apply)

• DNA contains uracil; RNA contains thymine.
• DNA is single-stranded and contains ribose; RNA is double-stranded and contains deoxyribose.
• DNA is found in the cytoplasm; RNA is found in the nucleus.
• DNA is double-stranded and contains deoxyribose; RNA is single-stranded and contains ribose.
• DNA contains thymine; RNA contains uracil.

Multiple Choice

Why is DNA Replication called a "SEMICONSERVATIVE MODEL"? (CHOOSE ALL ANSWERS THAT APPLY)

• Each new DNA molecule contains two original strands.
• Each new DNA molecule contains one original strand and one new strand.
• DNA replication results in two identical copies of the original strand.
• The process of DNA replication is entirely random without any template.
• DNA molecule contains one original strand which conserves energy.

Multiple Choice

What is the difference between DNA transcription and DNA translation?

• DNA transcription and translation are the same process that occurs simultaneously.
• DNA transcription occurs in the cytoplasm, while DNA translation occurs in the nucleus.
• DNA transcription involves copying DNA to RNA, while DNA translation involves making proteins from RNA.

• DNA transcription creates DNA from RNA, while DNA translation converts RNA to DNA.
