<h2>Problem of protein alters the movement of Ions </h2>
Explanation:
- Proteins are tiny machines that do explicit occupations inside a cell. The directions for building every protein are encoded in DNA. Proteins are gathered from building squares called amino acids.
- The CFTR protein is comprised of 1,480 amino acids. When the CFTR protein chain is made, it is collapsed into a particular 3-D shape. The CFTR protein is formed like a cylinder that experiences the film encompassing the cell, similar to a straw experience the plastic top on a cup.
- In individuals with CF, changes in the CFTR quality can cause the accompanying issues with the CFTR protein:
- It doesn't function admirably
- It isn't delivered in adequate amounts
- It isn't delivered in any way
- At the point when any of these issues happen, the chloride particles are caught inside the cell, and water is never again pulled in to the space outside the cell. When there is less water outside the cells, the bodily fluid in the aviation routes gets got dried out and thickens, making it smooth the cilia. The cilia can't clear appropriately when thick, clingy bodily fluid overloads them.
I believe the answer id Cnidaria
Answer:
D. Aa
Explanation:
Given:
Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa
Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa
Now if both cross and fertilization occurs, we have:
A a
a Aa aa
a Aa aa
The offsprings are (Aa, Aa, aa, aa)
Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.
Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
