Thymine

Which nitrogen base is not found in RNA?

Guanine

Adenine

Cytosine

Thymine

false

The flow of genetic material is usually from RNA to protein to DNA.

True

False

produces molecules that are half new and half parent DNA

DNA replication is a semiconservative process because it:

generates ADP and ATP molecules

uses little ATP

produces molecules that are half new and half parent DNA

produces molecules that are 100% new DNA

5' to 3'

DNA replication occurs in a ________ direction.

3' to 5'

5' to 3'

1' to 3'

3' to 1'

introns

What is spliced out of eukaryotic mRNA before it is transported out of the nucleus before it is translated?

rRNA

phosphate groups

exons

introns

tRNA

This molecule carries an amino acid and anticodon during translation.

DNA

rRNA

tRNA

ATP

Transposons

Segments of DNA that have the ability to move from one location to another

Conjugation

DNA is transferred between cells through a cytoplasmic bridge after a conjugation pilus draws the two cells close enough to form the bridge

transformation

The cell takes up DNA directly from the environment

transduction

A bacteriophage injects DNA that is a hybrid of viral DNA and DNA from a previously infected bacterial cell

true

Recombinant DNA techniques are used to make large quantities of a desired protein.

True

False
