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

Answer:
1. I show people I'm trust worthy by looking at them in there eyes and promising that I would never let a secret or anything trust worthy break my promise.
2. I feel mistreated and just shameful because I'd blame my own personality and insecurities to be the reason why that person disrespects me.
3. A time I found it hard to be fair with someone is whether I'm defending my brother or a friend. I just snippy think that I stand up for my brother more.
4.Good Citizenship that I have seen in my community was actually today. My Grandmother's fire alarm went off today while I was in the building and all the neighbors checked on eachother to make sure everyone's ok.
5. I show other people I respect them by agreeing to them in subjects that I also believe in. I respect them by being polite.
6. I think the only way you can truly see if someone cares for you, is if you put thin through hell. If you talk about really meaningful things going on in you're life and you see that person responding with Advice and care, I'd really appreciate it and think that they really do care about me and my problems. They don't shrug off any questions or beat around the bush. They always ask how ur doing and Always check up on you to see if you took there advice. But maybe I'm wrong. That's just what I feel and think when I saw the question.
7. Honestly I get into lots of arguments with lots of people. I've just learned to not care and just don't listen and I think that's really helped me with my Self Control.
8. Uhm something that I've had trouble persevering through is the death of my grandfather this past may. I talk a lot about my grandfather but sometimes and everytime I get into this type of question it bothers me because I cried all day and night and was truly lost. I did not want to do anything. I wasn't sure how to "move on" as everyone days when they lose someone. I just didn't want to do anything. Didn't want to see anything. And you know the rest. I guess this isn't a good answer to you're question because in the end I did kinda persevere and I did it only because I had a dream of him about a week or 2 after he died and he sayed "don't cry, I'm ok". That really helped me out and I just want to give him the rest of the world that we have left.
I hope I helped you . Good luck.
Answer:
Staying well-hydrated can be a key part of your plan to "get things moving" again. Water is important for your digestion. It keeps the food you eat moving through your intestines, and it keeps your intestines smooth and flexible, too.
