Answer:
The correct answer will be option-A.
Explanation:
Deoxyribonucletoide stands for DNA, the genetic material of the organisms. This DNA is the hereditary material of the organism coding molecule is passed on to the generations, so it has to be replicated, form a transcript and translated to proteins.
The DNA transcription process produces a transcript chemical molecule with exactly the same language as of DNA called RNA. This RNA carries the information for the synthesis of protein molecule so it acts as a messenger molecule and is known as mRNA.
Other types of RNA molecules are produced by the DNA which is named depending on the functions like transfer RNA or ribosomal RNA.
Thus, option- A is the correct answer.
Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
