Answer:
Mother - XAXA
Father - XY
Explanation:
Please see the attached image - complete question
Solution -
In the second cross the female is affected while the male is unaffected
The disease mentioned in the question is dominant X inked which means even one X chromosome can cause the disease. Thus, it will impacts males more than females.
Let the allele representing a diseased X gene be XA
and the allele for normal X gene be X
The offspring have all diseased males, which means that the genotype of affected female will be XAXA
And the genotype of unaffected male will be XY
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Extreme stress condition is a predisposing factor for respiratory alkalosis.
Respiratory alkalosis is the disruption of body's acid base balance due to high carbon dioxide levels in the body. It is a more common condition in people with rapid and uncontrolled breathing. The symptoms of the disorder include dizziness, bloating, confusion, dry mouth, etc. The pH of the body is generally above 7.45 during respiratory alkalosis.
Stress is the psychological condition where a person takes excessive tension. It can lead to other conditions like anger, nervousness, irritation, etc. Stress can generally cause shortness of breath in a person, eventually leading to respiratory alkalosis.
