Mitochondrial DNA can be traced for generations, is the best characteristic of mitochondrial DNA.

Further Explanation:

Mitochondria are present mostly in eukaryotes and not present in single celled organelle like RBC which lack nucleus.

Function of mitochondria:

  • Regulates membrane potential
  • Power house of cell
  • It’s the site where TCA cycle occurs.

The metabolism cycles that is Calvin cycle and electron transfer chain takes place in the mitochondria. Here the chemical part that is the glucose derivatives is converted into energy rich molecules (ATP). This compound helps in the formation of energy. Thus, mitochondria are the site of this conversion.

Mitochondria are made up of two membrane, outer layer and inner layer. The space between the two membranes called intermembrane space. The space enclosed by inner membrane is called matrix, inner membrane consists many folds to expand the surface area for ATP synthesis.  

Mitochondria also consists small circular mitochondrial DNA. These mitochondrial DNA transfer the information from parent to the offspring. Mainly proteins present in mitochondria are encoded by the mitochondrial DNA. It produces very important enzymes that are responsible in the process of producing energy. The mitochondrial DNA is mainly inherited from mother not like nuclear DNA that is inherited fr om both the parents. The size of the mitochondria DNA is around 16 kbp.

<span>the one that best describes mitochondrial DNA (mtDNA) would be: c.Mitochondrial DNA can be traced for generations. As the name suggest, mithocondrial DNA exist within every copies of DNA on our body. This means that mithocondrial DNA can be inherited from both of our parents, which means it can be traced for generations</span>

Lesch-Nyhan syndrome is an X-linked, recessive condition caused by mutation of the HPRT1 gene responsible for purine metabolism.
Elanso [62]

Answer:

B. The father did not contribute a sex chromosome to his daughter due to nondisjunction of the sex chromosomes. The daughter is XO and her only X chromosome came from her mother, who was a carrier.

A.The mother's X chromosomes failed to separate during meiosis, and the daughter inherited two X chromosomes with the Lesch-Nyhan mutation. The father contributed no sex chromosomes.

Explanation:

As seen in the question above, a little girl was diagnosed with Lesch-Nyhan syndrome, which is an X-linked recessive condition caused by a mutation in the HPRT1 gene responsible for purine metabolism.

The little girl's parents do not have the syndrome, and no one in the little girl's paternal family presented this syndrome, however, we know that the maternal grandfather of the little girl's mother had the syndrome, which means that it was the mother's genetic material that contributed to the development of the syndrome in the little girl. This was because the little girl did not receive any X chromosomes from her father, but she inherited the two X chromosomes from her mother that coded for the Lesch-Nyhan mutation. This happened because the mother's X chromosome disjuction did not occur during meiosis I.

As shown above, the father did not contribute any sex chromosomes to his daughter, which means that the daughter is XO and her only X chromosome came from her mother, who was a carrier.

In an experiment, the membrane potential of a neuron is hyperpolarized to –120 mV. When an inhibitory neurotransmitter is applie
denis-greek [22]

Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm  to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of  inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium  gated channels, which  were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.

By definition, a compound microscope possesses:
valkas [14]

Answer:

two sets of magnifying lenses

Explanation:

This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the

two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.
