DNA/DNA REPLICATION REVIEW

What is the difference between DNA and RNA?

• DNA contains ribose sugar, while RNA contains deoxyribose sugar.

• DNA contains deoxyribose sugar, while RNA contains ribose sugar.

• DNA is single-stranded, while RNA is double-stranded.

• DNA is found in the nucleus, while RNA is found in the cytoplasm.

What is the role of the ribosome in protein synthesis?

• Translates mRNA into a polypeptide chain.

• Synthesizes DNA from RNA.

• Degrades proteins into amino acids.

• Facilitates the transport of proteins to the cell membrane.

What is a section of DNA that codes for a specific protein called?

• Chromosome

• Gene

• Nucleotide

• Allele

What is a mutation?

• A change in the DNA sequence that can lead to changes in protein function.

• A process that repairs damaged DNA sequences.

• A type of genetic engineering used to create new species.

• A method of cloning organisms for research purposes.

What is the purpose of DNA replication?

• To ensure that each new cell receives an exact copy of the DNA.

• To create genetic diversity among cells.

• To repair damaged DNA strands.

• To facilitate protein synthesis in the cell.
