DNA, RNA, and Protein Synthesis

mRNA is made from DNA during what process?

• Transcription

• Translation

• Both of these

• Neither of these

Which of these is part of a DNA nucleotide?

• glucose

• ribose

• deoxyribose

• amino acids

Which base is normally present in DNA but absent in RNA?

• A

• C

• T

• G

The DNA code for a particular amino acid contains a sequence of how many nucleotides?

• 5

• 6

• 4

• 3

A strand of DNA consists of thousands of smaller, repeating units known as

• lipids

• proteins

• nucleotides

• amino acids

Based on structure, how does DNA differ from RNA?

• RNA contains uracil, DNA does not

• DNA is double stranded, RNA is triple stranded

• RNA is a helix, DNA is not

• DNA has 4 nitrogen bases, RNA has 3 nitrogen bases

This is a molecule of

• ATP

• DNA

• RNA

• Protein

Knowledge of DNA is important because DNA

• stores food

• transmits genetic info

• transmits energy

• stores enzymes

"May contain adenine, guanine, cytosine, and thymine"

• RNA only

• DNA only

• Both DNA and RNA

• Neither DNA or RNA

In what organelle is mRNA made from DNA?

• ribosome

• centriole

• nucleus

• cell membrane
