Protein Synthesis, DNA, & RNA

What is the monomer for nucleic acids?

• monosaccharide

• amino acid

• nucleotide

• fatty acid

What are the three parts of a nucleotide for DNA?

• Deoxyribose sugar, nitrogen containing base, phosphate group

• Deoxyribose sugar, fatty acid chains, phosphate group

• Ribose sugar, nitrogen containing base, phosphate group

• Ribose sugar, nitrogen containing base, hydrogen bonds

What is the name of the circled portion of this nucleotide?

• The phosphate group

• The 5-carbon sugar

• The nucleic acid

• The nitrogenous base

What is NOT a difference between RNA and DNA?

• RNA is single-stranded, while DNA is double-stranded.

• DNA has the nitrogenous base Thymine, while RNA has the nitrogenous base Uracil.

• DNA is only found in the cytoplasm, while RNA is only found in the nucleus.

• DNA contains the sugar deoxyriboose, while RNA contains the sugar ribose.

Which type of RNA is located in the cytoplasm of the cell, makes ribosomes, and directs the translation of mRNA into proteins?

• mRNA

• rRNA

• tRNA

• μRNA

What are nitrogenous bases bonded with in between?

• single hydrogen bonds

• double hydrogen bonds

• single carbon bonds

• double carbon bonds

Which nitrogenous bases do NOT bond together?

• A-------T

• A-------U

• G------C

• T-------U

What is it called when DNA makes a copy of itself?

• Replication

• Translation

• Transcription

• Transformation

Where does transcription take place in the cell?

• Within the cytoplasm

• Within the ribosomes

• Within the nucleus

• Within the mitochondria

The process of which mRNA codons are coded for amino acids, which then lead in to polypeptide chains is called:

• Transcription

• Replication

• Translation

• Transformation
