Exam #4 Practice Quiz

What is DNA replication?

• DNA replication is the process of copying DNA to produce two identical DNA molecules.
• DNA replication is the process of breaking down DNA into smaller fragments.
• DNA replication is the process of converting RNA into DNA.
• DNA replication is the synthesis of proteins from amino acids.

What is transcription?

• Transcription is the process of translating RNA into DNA.
• Transcription is the synthesis of proteins from amino acids.
• Transcription is the replication of RNA into DNA.
• Transcription is the process of copying DNA into RNA.

What is translation in our bodies?

• Translation is the process of protein synthesis from mRNA in cells.
• Translation is the breakdown of proteins into amino acids.
• Translation is the conversion of proteins into carbohydrates.
• Translation is the process of DNA replication in cells.

What enzyme makes a copy of DNA during DNA replication?

• RNA polymerase
• Helicase
• DNA polymerase
• Ligase

What does helicase do?

• Helicase repairs DNA strands.
• Helicase synthesizes RNA.
• Helicase transports proteins.
• Helicase unwinds DNA strands by breaking the hydrogen bonds

What does RNA polymerase do?

• RNA polymerase synthesizes RNA from a DNA template.
• RNA polymerase transports amino acids to ribosomes.
• RNA polymerase synthesizes DNA from an RNA template.
• RNA polymerase breaks down RNA into nucleotides.

Where does transcription take place?

• nucleus
• cytoplasm
• ribosome
