Answer:
Reciprocal cross
Explanation:
a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. In this type of test cross, male of one genotype and female of different genotype are crossed and the opposite is true as well. ( i.e the female of one genotype and male of different genotype are crossed.)
As we can see in the male Flagus fly with the Barkus phenotype is being crossed with a female with the wild-type phenotype.
In the second test, we can see that the opposite is true of our first statement where the female Flagus fly has the Barkus phenotype and the male has the wild-type phenotype after being crossed again thereby reversing the genotype.
Gram negative and Gram positive refers to if bacteria retain the Gram Stain or not. Gram positive do. Gram negative do not. Gram positive bacteria will appear purple/blueish after staining. <span>It is important because whether a bacteria is Gram positive or negative helps determine the species, characteristics of disease, and the best antibiotics to use in treatment. </span>
Only alpha and beta ray will be affected because they are charged with positive and negative ions respectively. In Electric field, they will be moved(i cant figure out a suitable word). THey move in a hyperbolic path and follows the positive and negative terminal. Both the alpha and beta will flow to opposite to each other where alpha will move to the negative terminal and beta will move to the positive terminal. In magnetic field, its more complicated then electric field. U eva heard of the Left Hand Flemming Rule?, Its hard to explain without a diagram. Maybe u shud search out urself. They will follow a circular path. In both fields, alpha will move less while beta will shift more because alpha is heavier then beta.
As i say just now, gamma is not affected by both fields because it isnt charged
Answer:
The correct answer will be option-DNA polymerase can only add nucleotides to the free 3' end
Explanation:
DNA replication process produces the exact copy of DNA which requires various enzymes. The function of adding a nucleotide to the daughter strand is performed by the enzyme called DNA polymerase.
The DNA polymerase enzyme catalyses the process of DNA replication which requires energy provided by the dNTP. The enzyme adds new nucleotides at 3'-OH end of the DNA which favour the reaction energetically.
Thus, the new DNA strand appears to be elongated in the 5' to 3' direction.
