Answer:
C.
Explanation:
When it is said that a gene is "turned off" this usually means that this particular gene is no longer making the directions that need to be followed in order to make proteins. Therefore the proteins that are needed for a specific job, such as tolerating lactose, are not being produced. So the answer in this question would be that the RNA for that gene is not translated into protein.
For the answer to the question above, I think the answer is "will lack A and B red blood cell antigens"
Type O blood is lacking of some of the antigens that the A & B blood cells have. Hope this helps
Pests can be controlled by cleaning out garbage.
<h3>What are pests?</h3>
Pests are those organisms that cause damage to crops, livestock or food. Pests pose the greatest threat to food storage and threaten food security.
The best way to prevent pests are;
- Regularly inspect the building or site for Evidence of pests
- Reduce pest access points and harboring areas as much as possible
- Hang fly traps over the food prep and display areas
- Spray pesticide everywhere Keep food on the top shelf
- Clean garbage area as often as possible.

Answer:
The correct answer would be 5' capping, 3' polyadenylation , and intron splicing.
In eukaryotes, transcription results in the formation of pre-mRNA which needs to be processed in order to become mRNA (messenger ribonucleotide).
The pre-mRNA processing include:
- Addition of 5'cap (usually modified guanine nucleotide) at the 5'-end of the RNA. It prevents the RNA degradation and also help in the attachment of ribosome for translation.
- Addition poly-adenine (poly-A) tail at the 3'-end of the RNA. It increases the stability of the RNA and helps in its export out of the nucleus.
- Lastly, splicing takes place which removes the introns and joins the exons. Alternative splicing can also take place in order to produce many mRNA from a single gene.
