Protein Synthesis Exam/ Knowledge Test Exam Questions
with Correct Verified Answers/ Latest Update 2024.
transcription - ANSWER - process by which a section of DNA is used to produce a single-stranded RNA
molecule
translation - ANSWER - the process whereby genetic information coded in messenger RNA directs the
formation of a specific protein at a ribosome in the cytoplasm
Which organelle is the primary site of protein production?
• nucleus
• ribosomes
• cytoplasm
• cell membrane - ANSWER - ribosomes
Which describes a promoter?
• the first part of an operon that regulates where, when, and to what level a gene is expressed
• the part of an operon that, if attached by a repressor protein, suppresses the expression of a
gene
• a cluster of genes that are expressed or repressed as a group
• an enzyme that helps DNA unzip prior to transcription - ANSWER - the first part of an operon
that regulates where, when, and to what level a gene is expressed
Which summary below correctly describes what occurs during transcription?
• A DNA template is used to create an mRNA strand.
• An mRNA template is used to create a DNA strand.
• A DNA template is used to create a ribosome.
• An mRNA template is used to create a tRNA strand. - ANSWER - A DNA template is used to create
an mRNA strand.

, Which occurs during translation?
• mRNA is created by using a DNA template.
• mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein.
• Protein is formed when a polypeptide chain is broken apart and released from ribosome.
• One strand of DNA is copied into a strand of rRNA. - ANSWER - mRNA codons are joined by tRNA
anticodons to assemble amino acids to form a protein.
During which process is mRNA converted into a sequence of amino acids for protein production?
• transcription
• translation
• translocation
• mRNA synthesis - ANSWER - translation
Which describes the function of a peptide bond?'
• It connects amino acids.
• It connects ribosomes.
• It connects tRNA.
• It connects anticodons. - ANSWER - It connects amino acids.
Which is the purpose of transfer RNA?
• to code for protein synthesis
• to carry the synthesized genetic information from the nucleus to the ribosomes
• to synthesize proteins from RNA
• to bring amino acids to the ribosomes to be assembled into proteins - ANSWER - to bring amino
acids to the ribosomes to be assembled into proteins
Which occurs during transcription?
• DNA is copied to create a second DNA strand.
• mRNA codons and tRNA anticodons assemble amino acids.
• DNA is unzipped with the aid of DNA polymerase.
• mRNA is synthesized from a strand of DNA. - ANSWER - mRNA is synthesized from a strand of
DNA.
Which nucleic acid provides the master code for protein synthesis?
• DNA
