It's always better to have more than one prevention method to lower the chances. I would say, first, use a condom. second, Claire can start her birth control pills and take them responsibly.
a. A translation stop codon is added at the 3' end of the pre-mRNA.
c. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
d. Coding sequences called exons are spliced out by ribosomes.
Explanation:
In eukaryotes, during protein synthesis, the RNA must exit nucleus through the pores on the nuclear membrane and enter into the cytoplasm to undergo translation.
The exit processes of mRNA are: the 5’ capping, 3’ Poly-A tail, and pre-mRNA splicing.
The 5’capping is the initial step with addition of 7-methylguanosine cap to the 5’ end of the mRNA by phosphate linkage. This process protects the mRNA from degrading and helps to initiate translation processes.
The 3’ Poly-A tail step is the cleaving of pre-mRNA and addition of addition of around 200 A nucleotides or the 3’poly (A) tail to the mRNA by the poly (A) polymerase enzyme protein complex. This prevents pre-mRNA degradation, facilitates movement of mRNA to the cytoplasm, and initiates translation.
Pre-mRNA splicing is done to remove the introns from the mRNA because they are not part of function protein coding. The exons which take part in protein coding sequence are spliced once the introns are excised.
Finally, the resultant mRNA will exit the nucleus and enter the cytoplasm to undergo translation

The answer would be C. Sportsmanship.
There you go :)
Well when teens fight they may be going through some things in their life. We can't just place a reason for them, but one that makes sense for this is A. The cannot control their anger.
For this one you have to use pressure and a cloth : A. <span>Wrap the detached tissue in cloth.
For this one it is involved in the </span><span>cardiovascular system aka the circulatory system.B. hypertension is your answer. It is high blood pressure.
This one is obvious. It is D. stores that sell tobacco to minors.
I'm not sure about this last one I'm sorry.
Hoped I helped!</span>
