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.

The correct answer is he's screwed because with enough training in a mock scanner, the fMRI is sure to work.

The FBI kidnapped Mike and put him in an fMRI machine to track whether he was lying or not. FBI detects lies from the flow of blood. when he is lying, his brain put more efforts and more flow of blood.

fMRI detects lies according to brain activation patterns. Its brain activation patterns shoed different from the person who is innocent.

The flow of blood in activated areas helps in tracking lies using an fMRI machine. So, during the lie detection areas highlighted if a person lies.
