The transcription terminator stops DNA polymerase, AND results in the polymerase falling off the DNA template. adds a terminator
Ivan

Answer:

Results in a hairpin loop structure in RNA, AND results in the polymerase falling off the DNA template.

Explanation:

As the RNA polymerase arrives at the terminator site, it pauses. The termination of RNA transcription occurs when an RNA transcript with a self-complementary sequence is formed leading to the formation of the hairpin structure. The hairpin structure has 15-20 nucleotides.  

The hairpin structure of RNA weakens A=U base pairs in RNA-DNA hybrid and/or weakens the interaction between RNA and RNA polymerase. The overall effect is the dissociation of RNA polymerase from the complex and termination of the transcription.

We would expect that a 15-nucleotide sequence that includes a stop codon at the end (as part of the 15-nucleotide sequence) will
kirill [66]

Answer:

4 amino acids.

Explanation:

To become translated into protein, a sequence is read in triplets called codons.

Each codon that codes for an amino acid is made up of 3 nucleotides.

Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)

However, we are told that there is a stop codon at the end of this sequence.

A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.

Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.

Would the amount of cytosine and guanine be equal to each other in an RNA molecule?
allochka39001 [22]

Answer:

No

In RNA their arn't any base pairs but instead there are simply one base pairs, so any cytosine and  guanine molecule are not related to each other at all, and thereby they don't have to be the same amounts.
