Question 1

(True False)

Free
Small RNAs that regulate translation by binding to the leader region of mRNAs are called antisense RNAs.

Answer

Question 2

(Multiple Choice)

Free
An sRNA is isolated from a bacterial cell.What would you do to determine whether it is a cis-encoded or a trans-encoded sequence?

A)Identify whether or not the sRNA sequence is complementary to the coding strand of mRNA gene target.
B)Analyze the molecular position of hydrogen atoms in the sRNA nucleotides.
C)Determine whether the sRNA binds to mRNA or to tRNA.
D)Find out if the sRNA acts as a transcriptional or as a translational inhibitor.

Answer

Question 3

(True False)

Free
During regulation by attenuation in the trp operon,if the pause and terminator loops form in mRNA,transcription is uncoupled to translation and protein synthesis is not occurring.
