Positively charged DNA migrates more rapidly than negatively charged DNA b. Longer DNA fragments migrate farther on a gel than s
horter fragments c. Migration distance on a gel is inversely proportional to DNA fragment size d. Uncut DNA migrates farther on a gel than DNA cut with restriction enzyme
<h2>c. Migration distance on a gel is inversely proportional to DNA fragment size </h2>
Explanation:
Deoxyribonucleic acid is a genetic material that is a type of macromolecule.
It is made up of a monomer that ais called a nucleotide. Each nucleotide is made up of a deoxyribose sugar, a base, and a phosphate group.
Due to the presence of phosphate group DNA has negative property. When the DNA is separated by the gel electrophoresis method the size of the fragment of the DNA plays an important role.
Those DNA fragments that are small in size migrate faster than those DNA fragments that are larger in size.
So the migration distance is inversely proportional to the DNA fragment size.
<span>Homologous chromosomes exchange DNA during meiosis in a process called crossing-over. Crossing-over sometimes involves an unequal swapping of DNA. Basically one chromosome in the pair gets extra DNA.</span>
Explanation: if the parents are both RB, one would end up red, one would end up blue, and 2 would be heterozygous and end up presenting the incompletely dominant color of purple.
