Answer:
Mitochondrial DNA is useful as a molecular clock because it displays uniparental inheritance
Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW

Answer:
A - G1 phase
B - G2 phase
C - S phase
D - Mitosis
E - Interphase
Explanation:
Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase
G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.
During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.
Augusto should call a physical anthropologist to know if the bones he encountered on his farm are human bones.
<h3>Who is an anthropologist?</h3>
An anthropologist is a person versed in the holistic scientific and social study of humanity, mainly using ethnography as its method.
Anthropologists study the origin, development, and behavior of humans by examining the cultures, languages, archeological remains, and physical characteristics of people in various background.
According to this question, Augusto is a farmer who encounters several bones while plowing his field.
However, to know if these bones are human's, Augusto should call a physical anthropologist because they deal with the evolution of humans, their variability, and adaptations to environmental stresses.

Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
