Answer:
mtDNA is used, consider forensic laboratories to characterize bone remains and identify individuals who have other evidence
The disadvantage of using mtDNA in relation to nuclear DNA is that it does not identify individuals unambiguously, it only detects relationships between groups of individuals
Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
Answer:
B, G , E, F.
Explanation:
Hemoglobin is known to be a tetrameric hemeprotein, which is found in the erythrocytes where it binds with oxygen,and then the bound oxygen is transported to parts of the body.
Myoglobin is a monomeric protein that is found in the muscle tissue. Its function is that, it serves as intracellular storage site for oxygen.
It should be understood that, both hemoglobin and myoglobin are hemeproteins with physiological importance of having the ability of binding molecular oxygen.
In this case, it is also known that, the two, that is hemoglobin and myoglobin have a prosthetic group called heme, which is described or known to be a tightly bond, specifically a non-polypeptide unit which is required for biological function of some protein.
Mitochondria would be at a relatively small number for a cell with relatively few energy needs.
Prions are infectious agents that are made up of proteins which can fold in multiple ways. The three dimensional folding shape of a prion is determined by folding and intra molecular bonding of the linear amino acid chain. The folding and the intra molecular bonding on the other hand is determined by the amino acid sequence in the prion.
