D would be the correct answer/all of the above.
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:This would effect you life in many ways, for one if your partner has an STI then that mean you could contract that also and that can lead to many health issues for you in the future, if you are female it could risk your chance of having kids. To talk with your partner you should probably just confront the situation so thing don´t get worse. With your family member it will be harder if they dont know you are sexually active but you should still talk with them because they can offer you help in the situation
Explanation:
Family member that told them to take her off of life support
There are only three ways to manage time: thoughts, conversations and actions. Regardless of the type of business you own, your work will be composed of those three items.
As an entrepreneur, you may be frequently interrupted or pulled in different directions. While you cannot eliminate interruptions, you do get a say on how much time you will spend on them and how much time you will spend on the thoughts, conversations and actions that will lead you to success.
