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.
please ad more detail please. please. please. XD
Answer:
C) More momentum
Explanation:
The heavier the object the more momentum it has if it has the same Velocity at all masses.
Answer:
Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds. Vestigial structures can become detrimental, but in most cases these structures are harmless; however, these structures, like any other structure, require extra energy and are at risk for disease.
