Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
The classification of organisms is achieved in the branch of science called taxonomy. Classification is important in order for future references and understanding of the common properties and characteristics of organisms for research and easy skimming of characteristics. This is for organization and convenience purposes
1. Phosphate
2. Pentose sugar
3. Nitrogenous Base
Bc they create raw materials which converts directly to energy
