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.
Answer:
I am pretty sure that it is Vertebrates for the first question.
The variables that i would predict to be regulated by the body using a homeostatic mechanism are; amount of pressure which moves fluids in the body; amount of heat in the body; amount of water in the body;
Homeostasis is best described as the maintenance of a stable internal environment in spite of a changing external environment.
Answer:
Option B
Explanation:
Given
Number of incidences or frequency of an autosomal recessive disease 
As per Hardy Weinberg's equation, frequency of a recessive genotype is 
As per first equation of Hardy Weinberg's -
so ,
As per second equation of Hardy Weinberg's -
Substituting the given values in above equation, we get -
![\frac{9801}{10000} + \frac{1}{100} + 2pq=1\\2pq = 1-(\frac{9801}{10000} + \frac{1}{100})\\2pq = 0.99%\\OR[tex]2pq=1](https://tex.z-dn.net/?f=%5Cfrac%7B9801%7D%7B10000%7D%20%2B%20%5Cfrac%7B1%7D%7B100%7D%20%2B%202pq%3D1%5C%5C2pq%20%3D%201-%28%5Cfrac%7B9801%7D%7B10000%7D%20%2B%20%5Cfrac%7B1%7D%7B100%7D%29%5C%5C2pq%20%3D%200.99%25%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3EOR%3C%2Fp%3E%3Cp%3E%5Btex%5D2pq%3D1)

Hence, option B is correct.
