In the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.
<h3>What do you mean by Gel electrophoresis?</h3>
Gel electrophoresis may be defined as a technique that separates DNA, RNA, and proteins on the basis of their molecular weight.
As we all know, DNA fragments are negatively charged in nature, and hence they always move towards the positive pole of the electric field.
Therefore, in the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

Answer:
C. On average, 25% of the children are affected by the autosomal recessive disease if both parents are carriers.
Explanation:
A recessive trait is always expressed in homozygous genotype only. To have progeny with recessive traits from two normal parents, both the parents should be heterozygous carriers. For example, two normal parents with genotype "Aa" have 25% of the chances to have a child with homozygous recessive genotype (Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa).
An autosomal trait is equally expressed in both males and females. Inbreeding increases the homozygosity and thereby, increases the risk of expression of recessive traits which are otherwise masked in heterozygous genotype.
Answer:
Fruting bodies
Explanation:
Fungi can produce spores on somatic hyphae or on special spore producing hyphae which are arranged into structers called fruting bodies.
