question 44

Multiple Choice

The three steps that are required for DNA replication are

• A) unwinding, complementary base pairing, and joining.
• B) base doubling, unwinding, and joining.
• C) complementary base pairing, transcription, and translation.
• D) unwinding, transcription, and translation.
• E) unwinding, base doubling, and base pairing. In DNA replication, the DNA is first unwound by helicase. Then, new complementary nucleotides are positioned by complementary base pairing to each strand. The new nucleotides are then joined into a new strand.

Circadian Rhythms

Biological processes or cycles that occur on a roughly 24-hour schedule in living organisms, governing physiological and behavioral changes.

Continual Darkness

An environmental condition where there is a constant absence of light, which can affect growth, behavior, and biological rhythms in organisms.
