Answer:
Mitochondrial DNA accumulates DNA mutations quickly. Because of this, it would be most beneficial in analyzing the ancestral relationship of organisms that are
A. Mitochondrial DNA is beneficial in both of these cases
B. Distantly related
C. Mitochondrial DNA is not used to analyze relationships
D. Closely related
Explanation:
Mitochondrial DNA <em>does not serve to identify individuals without ambiguity</em>, but to detect kinships between groups of individuals; it is then used for comparisons between missing persons and unidentified remains and their relatives.
<u><em>The answer is</em></u>: <u>D. closely related.</u>
If a restriction site is altered, a higher molecular weight band will be observed.
Restriction enzymes are proteins synthesized by bacteria to protect itself against foreign DNA. These enzymes cut DNA at specific places.
This enzyme is used to detect mutations in the genome, particularly those at the sites of action of these restriction enzymes. A healthy subject is compared with the patient who is supposed to have cystic fibrosis. If their DNA migration is different, it means that their DNA is different and that there is a mutation at the restriction sites.
Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.
<h3>What is DNA?</h3>
All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.
The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.
The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.
