RNA & Protein Synthesis

During DNA replication, a DNA strand that has the bases CTAGGT produces a strand with the bases

• TCGAAC

• GATCCA

• AGCTTG

• GAUCCA

RNA contains the sugar

• ribose.

• deoxyribose.

• glucose.

• lactose.

Unlike DNA, RNA contains

• adenine.

• uracil.

• phosphate groups.

• thymine.

Which of the following are found in both DNA and RNA?

• ribose, phosphate groups, and adenine

• deoxyribose, phosphate groups, and guanine

• phosphate groups, guanine, and cytosine

• phosphate groups, guanine, and thymine

Which type(s) of RNA is(are) involved in protein synthesis?

• transfer RNA only

• messenger RNA only

• ribosomal RNA and transfer RNA only

• messenger RNA, ribosomal RNA, and transfer RNA

What is produced during transcription?

• RNA molecules

• DNA molecules

• RNA polymerase

• proteins

How many codons are needed to specify three amino acids?

• 3

• 6

• 9

• 12

What happens during the process of translation?

• Messenger RNA is made from DNA.

• The cell uses information from messenger RNA to produce proteins.

• Transfer RNA is made from messenger RNA.
