Genetics Test Review

Which enzyme is responsible for identifying the correct nucleotides needed during transcription?

• DNA polymerase

• DNA helicase

• RNA polymerase

• RNA helicase

Which DNA base pairs are correct?

• Adenine-Guanine

• Thymine-Cytosine

• Thymine-Adenine

• Guanine-Thymine

DNA replication is said to be a semiconservative process because,

• It does not require energy.

• It only happens when a new cell is made.

• Each new strand of DNA is one old strand and one new strand.

• It takes less nucleotides to make the new strand than the old one.

The transfer of genetic information from DNA to RNA is called

• transcription.

• translation.

• Initation.

• elongation.

Which two structures form the backbone of a DNA molecule?

• Protein and nitrogen base

• Nitrogen base and phosphate

• sugar and protein

• sugar and phosphate

Which enzyme is responsible for unzipping the DNA molecule in DNA replication?

• DNA polymerase

• DNA helicase

• RNA polymerase

• RNA helicase

DNA replication

• Produces one new daughter DNA molecule that is complementary to the original.

• Produces one new daughter DNA molecule that is complementary to the original.

• Results in the formation of four new DNA strands.

• uses each strand of a DNA molecule as a template for the creation of a new strand.

The making of a polypeptide (protein) from an mRNA strand is

• Translation.

• transcription.

• DNA replication.

• RNA replication.

Contains deoxyribose sugar

• DNA

• RNA

• Both

Moves from the nucleus to the cytoplasm

• DNA

• RNA

• Both
