RRNA is used to create a ribosome where translation occurs. So,more rRNA mean more translated proteins. But the cell need one Copy of DNA that contain the whole number of genes that the cell need to live or to make mRNA to make proteins.
Answer:
One importance in breeding agriculture plants is to improve the plant's yield, resistance against diseases, and ability to survive in cold conditions.
<em>(I'm assuming the question is asking what the importance is of artifically breeding plants, not literally breeding next to some plants. that would be weird)</em>
Answer:
The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).
Explanation:
Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.
The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.
The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.
Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
Answer:
RNA primer
Explanation:
the DNA polymerase can't synthesize DNA without an 3' ending, the primase enzyme synthesize an RNA primer that brings to the DNA polymerase the 3' spot so she can finally starts the new DNA chain.
