To which part of the mRNA sequence does the RIsc bind stop c

To which part of the mRNA sequence does the RIsc bind? stop codon O 5\' UTR O 3\' UTR O poly(A) tail O start codon

Solution

1. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by binding to the 3? untranslated region (3?UTR) of mRNAs.

So answer is 3\'UTR

2. RNA interference (RNAi) is a natural process in which cells silence unwanted or harmful genes by inhibiting translation. It is a process which cleaves long double-stranded RNA (dsRNA) molecules into short double-stranded fragments of ~20 nucleotide siRNAs. First step involves degradation of dsRNA into small interfering RNAs (siRNAs).

So answer is ubiquination of proteins


3.Chromatin immunoprecipitation, refers to a procedure used to determine whether a given protein binds to specific DNA sequence in vivo.

So answer is a technique that determine the specific location within the genome where protein interact with DNA
