Question

Multiple types of RNAs are involved in translation. Choose the all the types of RNAs and their functions in translation. a. mRNAs are templates that provide coding information to form proteins b. rRNAs are ribozymes that catalyze the addition of amino acids. c. mRNAs are adaptor molecules that contain amino acids. d. tRNAs are ribozymes that catalyze the addition of amino acids. e.rRNAs are templates that provide coding information to form proteins. O f. tRNAs are adaptor molecules that contain amino acids as well as bases that are complementary to an mRNA template. QUESTION4 Match the following steps with the stages of bacterial transcription and translation Promoter region on the DNA is bound by a holoenzyme made of RNA polymerase and sigma , a. Termination of transcription b. Initiation of transcription c. Termination of translation d. Elongation during transcription e. Elongation during translation Polyribosomes catalyze the addition of amino acids RNA polymerase catalyzes the addition of NTPs to the 3 end of the growing RNA A transcription-termination signal results in the formation of a RNA hairpin that releases RNA polymerase Release factor binds to the A site of the ribosome once it reaches the stop codon QUESTION5 DNA is a double-stranded helix. Which strand is involved in transcription? O a. Template strand (runs in the 5'-3' direction) b. Template strand (runs in the 3'-5' direction) O c. Leading strand (runs in the 3.-5. direction) O d. Coding strand (runs in the 3'- 5' direction)

Answer 1

I believe the correct answer to be:

A3)

Statement A), Statement B), Statement F)

A4)

Statemtent 1) = B) Initialtion of transcription
Statement 2) = E) Elongation during translation
Statement 3) = D) Elongation during translation
Statement 4) = A) Termination of transcription
Statement 5) = C) Termination of translation

A5) Option B) Template strand(Runs in 3; - 5' direction)
