The cystic fibrosis is a condition, in which the secretion of mucus in some vital organs such as lungs, pancreas, and stomach becomes sticky and thick.
This condition is caused by the inheritance of the recessive gene responsible for the development of the cystic fibrosis.
The thick and the sticky mucus gets lined up on the walls of the organ and causes the clogging of the tubes and the ducts, hence, instead of providing lubrication they act as clogging agent and causing major damage to some vital organs, especially, lungs and the pancreas.
Answer:
The preserved animal tracks should be stored with mold and should be traced, and any missing layers should be kept and be stored hard.
Explanation:
<h2>Mutation will occur </h2>
Explanation:
Base excision repair operates for small DNA damage such as deaminated bases
- DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
- Uracil is incorrectly paired with guanine then mutation will occur
- The original GC base pair will change into AT base pair(transition of GC to AT)
- Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
