Question
Every rRNA gene in the human genome contains which of the following?
A. A specific 3’TAC5’ sequence in the template strand
B. A specific sequence in the last exon of the template strand that is complementary to one of the stop codons
C. A promoter for binding of RNA polymerase
D. A sequence complementary to the poly-A tail
E. A sequence complementary to the ribosomal binding site
Which of the following is wrong about alternative splicing?
A single pre-mRNA produces various mature mRNAs.
Some of the introns are translated
Some of the exons may not be translated.
A gene can produce more than one protein.
Damaged DNA is selectively removed by the splicing machinery
Two of the above
A.A single pre-mRNA produces various mature mRNAs.
B.Some of the introns are translated
C.Some of the exons may not be translated.
D.A gene can produce more than one protein.
E.Damaged DNA is selectively removed by the splicing machinery
F.Two of the above
Explanation / Answer
e. A sequence complementary to the ribosomal binding site. The small ribosomal subunit contains rRNA that is complementary to the Shine-Dalgarno sequence. also known as ribosome binding site.
f. Two of the above. Damaged DNA is selectively removed by the splicing machinery. and Some of the introns are translated.
