How are rna hairpin turns related to termination in e. coli?

Biology
1 answer:
zloy xaker [14]3 years ago
7 0
I believe the answer is that the turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase. 
A hairpin loop is an unpaired loop of messenger RNA that is created when an mRNA strand folds and forms base pairs with another section of the same strand. Intrinsic termination of transcription in E.coli involves the formation of an RNA hairpin in the nascent RNA. The hairpin plays a central role in the release of the transcript and polymerase at intrinsic termination sites on the DNA template.

Which of the following mutations could result in a truncated protein? Choose all that apply. Which of the following mutations co
castortr0y [4]

Answer:

A truncated protein refers to a protein that gets shortened due to a mutation, which does not allow the process of translation to take place properly. The formation of a truncated protein can take place due to a frameshift mutation of one or two base pairs. In such kind of mutation, a single or two base pairs get withdrawn from the sequence resulting in the formation of a completely changed triplicate codon sequence, which may result in the generation of a truncated protein comprising a different set of amino acids.  

A nonsense mutation can also result in the formation of a truncated protein. A nonsense mutation generally codes for certain kinds of amino acid, however, post mutation can get converted into a stop codon. This transformation can result in the formation of a truncated protein.  

Deletion or insertion at the chromosomal level can also result in the formation of a truncated protein. As insertion and deletion of a certain concentration of DNA can probably lead to the formation of a novel codon that can either be a nonsense codon or a stop codon, which may eventually result in the formation of a truncated protein.  

Hence, the correct answers are statements 1st, 2nd, 3rd, 4th, and 6th
