Why isn't mitochondrial dna a unique identifier?
a. mitochondrial dna is inherited through the maternal lineage.
b. all female offspring inherit their mother's mitochondria, and therefore the same mitochondrial dna.
c. as a result, all female family members that share a maternal lineage would have the same mitochondrial dna.
d. mitochondrial dna can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
e. all offspring inherit their father's mitochondria, and therefore the same mitochondrial dna.

a. Mitochondrial DNA is inherited through the maternal lineage.

d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.

Explanation:

DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
