DNA and RNA Strands

DNA replication takes place in eukaryotic cells during which phase?

• G1

• S

• M

• G0

Based on the given data table of two bacteria, which of the following statements are true? (mark all that apply)

• S. pneumoniae has the most thymine in its nucleus.

• Both bacteria have less guanine than adenine.

• S. pneumoniae's amount of cytosine is more similar to guanine than thymine.

• E. coli's greatest amount of nitrogen bases is adenine.

What process is occurring in this picture?

• DNA Replication

• DNA Transcription

• DNA Translation

• DNA Synthesis

Each section of DNA that codes for a protein is called a...

• Chromosome

• RNA

• Gene

• Enzyme

DNA replication results in two DNA molecules,

• each one with two original strands

• each one with two new strands

• each one with one new strand and one original strand

• one with two new strands and the other with two original strands

In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in the cell nucleus, is called

• translation

• mutation

• DNA replication

• transcription

Fill in the complementary bases according to the base-pair rule in DNA: A T C C A G

• T U G G T C

• T A G G T C

• T A C G T G

• T A C C A C

DNA codes for...

• cholesterol

• proteins

• fatty acids

• a sandwich
