Question

#59)

During protein synthesis, what happens to the ribosome?

A) attach to the mRNA molecule and travel along its length

B) attach to the DNA molecule and travel along its length to produce an mRNA molecule

C) Translate mRNA into tRNA

D) Transcribe mRNA to tRNA

E) Translate mRNA into DNA

#60)

if you digested the human genome (3 billion bp) with a 7-cutter restriction enzyme, approximately how many fragments would you get?

A) 511461

B)183105

C)16384

D)88

E) None of the above

T/F question

1) In the absence of allolactose, the lac operon is constitutively transcribed.

2) when a structural gene is under positive inducible control, a mutation that eliminates the activator protein will cause the structural gene to be constitutively expressed

THANK YOU

Answer 1

Answer

59. Option A is the right answer because ribosome binds with mRNA and move along to translate the protein.

60. Option C is the right answer because of the average length of the fragment by seven cutter restriction enzyme will be n⁷, where n= base pair

4⁷= 16348
