Answer:
i. Their size and charge
ii. This is due to the fact that they move when an electric current is applied.
Explanation:
i. The components of DNA are of particular use in gel electrophoresis are their size and charge.
ii. This is because since the charge to mass ratio is constant for the DNA molecules, electrophoresis separates the molecules based on their sizes only. This is determined by the distance the DNA molecule moves in the gel. The smaller molecules move a large distance while the larger molecules move a small distance. This can thus be used to identify the molecules.
Answer:
<h2>(14+16)/1000 *100= 3</h2>
Explanation:
Parental combinations are always more common then other recombinant progenies.
A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b and between b & c, then the double cross is that, which occurs in both.
Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.
So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3
