5 0

Answer:

The correct answer will be option-D

Explanation:

RNA or ribonucleic acid is the nucleic acid which was formed in the primordial time. The RNA molecule acts as an enzyme called ribozyme and also acts as the genetic material of a few viruses.

The RNA is composed of nucleotide monomer where each nucleotide is made of a ribose sugar, a phosphate group and the nitrogenous base adenine, uracil, cytosine and guanine.

Thus, option-D is the correct answer.

Sonja [21]

Answer:

I'm not quit sure about this but I'm sure its hemophilia. Yes I'm a middles schooler who is answering a high schooler's question but in my biology class i do high school things here and there.

Explanation:

I'm sure it is hemophilia because 1. a father only passes one of his sex chromosomes which is either x or y (X for girl and Y for boy). 2. the new born can get, from the mother, either an x chromosome with the hemophilia or the other x with the normal blood clotting gene. I hope this helps and if not I am sorry

In the formation of ltp, the entry of ca2 iond inyo yhr neron activates, which are enxymes that contribute to the:_____.
Aliun [14]

In the formation of LTP, the entry of Ca2+ ions into the neuron activates protein kinases, which are the enzymes that contribute to the increased AMPA conductance of the postsynaptic cell.

<h3>What is LTP?</h3>
  • LTP or Long-Term Potentiation is a biological process due to which synaptic connections formed between different neurons grow stronger due to frequent activation.
  • It can be defined as a way by which the responses of brain change along with the experience thus dealing with learning and memory in the hippocampus.
  • It is caused by combining activity of presynaptic and postsynaptic neurons.
  • During synapses, Ca2+ is release as a neurotransmitter from the presynaptic neuron. This Ca+ enters the postsynaptic neuron and activates protein kinases.
  • The protein kinases increase the activity of AMPA receptors which plays an important role in neurotransmission through glutamate.
