DNA Replication

DNA is tightly coiled around proteins called

• histones

• chromosomes

• nucleosomes

• ribosomes

DNA condenses down into

• histones

• chromosomes

• nucleosomes

• ribosomes

histone + wrapped DNA =

• nucleosome

• chromosome

• ribosome

• RNA

When a cell divides, DNA must be copied. This process is called

• DNA replication

• RNA replication

• transcription

• translation

Enzyme that unzips the two strands of DNA

• helicase

• histone

• polymerase

• nucleosome

The location where the DNA strands are unzipped with the help of helicase is known as

• replication fork

• translation fork

• transcription fork

• replication spoon

This enzyme brings nucleotides to match one of the strands (known as the parent strand).

• polymerase

• helicase

• histone

• chromosome

The new sequence of DNA will exactly match the old sequence. This is due to

• base pairing

• being single stranded

• being semi-conservative

• being accurately transferred

The new DNA strand that is created is known as

• parent strand

• daughter strand

• son strand

• cousin strand

Because only half of each parent strand remains in the new DNA molecule, the process is called

• conservative

• semi-conservative

• conclusive

• cell division
