Question:
1. In DNA transcription, which of the following statements is/are accurate with respect to the definitions for the template versus the non-template DNA strands?
A) The non-template strand is the coding strand.
B) The template strand is the strand that is read and is turned into mRNA.
C) The coding strand will have the same identical sequence of nucleotides as the mRNA transcript (with the exception of containing thiamine instead of uracil).
D) All of the above (select ?D? of A, B and C are correct).
E) A & B (select ?E? if A and B are both correct).
2. Use this representation to answer the following question:
DNA template strand: 5' ___________________________ 3'
DNA coding strand: 3' ___________________________ 5'
Given the locally unwound double strand above and the way it is positioned on the page, in which direction (left to right or right to left) does the RNA polymerase move while transcribing DNA, and which strand is transcribed?
A. Left to right along the DNA coding strand.
B. Right to left along the DNA coding strand.
C. Left to right along the DNA template strand.
D. Right to left along the DNA template strand.
E. None of the above.
3. If the DNA base sequence in the DNA template strand for a particular amino acid is AGT , then which of the following choices could serve as the Anti-codon on the tRNA?
A. 5' AGU 3'
B. 5' TCA 3'
C. 5' UCA 3'
D. 5' ACU 3'
E. 5' UGT 3'
4. Which of the following is/are TRUE about anti-codon of tRNAs?
A. Like codons in the genetic code, anti-codons are also unambiguous.
B. Anti-codons are attached to CCA (reading 5? to 3?) at the 3? end of the tRNA.
C. Anti-codons bind to mRNA codons in an ant parallel fashion.
D. Anti-codons bind to the ribosome binding site during translation.
E. All of the above (select Answer E if A, B, C, and D are all TRUE).
5. Where do you find the ribosome binding site?
A. On the small subunit of the ribosome.
B. On the tRNA.
C. On the DNA coding strand.
D. On the p site of the large subunit of the ribosome.
E. On the mature mRNA transcript.
