Mutations can occur at higher rates in viruses.
Explanation:
The mutation rate of an organism refers to the rate or average number of errors which are formed in the genome of the organism’s progeny per base per replication cycle.
Accordingly the Mutations of viruses are the highest per base pair per generation mutation. Viruses can mutate more than a million times than the host’s body due to their virulence factor, evolution ability, and presence of a variety of traits.
Of the DNA and RNA viruses, the RNA viruses like the Retroviruses having a much higher rate, for example, the HIV virus which is a Retrovirus has high mutation rate.
Answer:
Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants
Explanation:
Axon guidance is a neural development subfield relating to the mechanism by which neurons send out axons to meet their right targets.
ABL gene is a protooncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes. PTPs are known to signal a number of cellular processes, including cell development, differentiation, mitotic cycle, and oncogenic transformation.
Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants.
Answer and Explanation:
Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.
Their wings skeleton have the shape of finger/hands like a human.
Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.
