3 0
By definition, a keystone predator is a predator that once it is eliminated from the food web, prey population thrives. This often leads to a decline in diversity within the food web. With this in mind, we can say that A and B are wrong. Additionally, from the information, we can say that D is the correct answer since they do play a very important role in the food web.

Processing of the mRNA begins before transcription of eukaryotic mRNA\'s is complete. The end of the mRNA is prepared for recogn
kompoz [17]

Answer:

The correct answer is

1. 5' end.

2. guanosine

3. 5′ to 5′ triphosphate linkage.

4. On the 7th position.

5. 2′ hydroxy-groups of the first 2 ribose sugars.

Explanation:

The eukaryotic mRNA is processed or modified with a guanosine cap at 5' end and poly-A tail at 3'end before translation.

The process of adding a cap at 5' end of a growing mRNA is known as capping. The process of capping adds guanosine nucleotide at the 5'-end of mRNAs by 5′ to 5′ triphosphate linkage. This guanosine is modified by methylating at the  7th position of the atom. The mRNA is further modified by methylation of first two ribose sugars at their 2′ hydroxy-groups. This capping is advantageous to the sequence as it protects the end from phosphatases and nucleases.
