|
| D. |
all of the above |
Which of the following does not occur before a eukaryotic mRNA is exported from the nucleus?
|
The ribosome binds to the mRNA. |
||
|
The mRNA is polyadenylated at its 3′ end. |
||
|
7-methylguanosine is added in a 5′-to-5′ linkage to the mRNA. |
||
|
RNA polymerase dissociates. |
Homework Answers
Q-1,D is the correct answer as enhancer are small region of DNA ,a place where transcription factor can also bind as they have DNA binding domains and these are open or relaxed region of dnaD
Q-2, A is incorrect as in eukaryotic cell trancrtranscr occur in nucleus and translation in cytoplasm so ribosome will bind to mRNA in cytoplasm so RIBOSOME BIND TO MRNA DOES NOT OCCUR .

Eukaryotic messenger RNA undergoes several processing steps after transcription before it binds to ribosomes as the template for protein synthesis. One of these steps is polyadenylation. Identify whether the statements below about polyadenylation are true or false. A polymerase adds a polyadenylate tail of about 10 nucleotides to the 3' end of the mRNA. A polymerase adds a polyadenylate tail to the mRNA while it is still in the nucleus. The polymerase forming the polyadenylate tail uses a polydT DNA...
