Answer: A. Dimerization (1), DNA binding (4), cAMP binding (3
Explanation:
Answer is A
Firstly axon must reach the threshold level and then depolarisation occurs. Depolarisation phrase means sodium enters and potassium leaves the axon . Choice C can't be because main idea is the entering of sodium ions.
<h2>Messenger RNA
</h2>
Explanation:
Messenger RNA results from the breakage and recombining of DNA strands that is known as transcription
- Transcription always starts at a specific site called promoter
- Promoter are specific sites on DNA where RNA Polymerase binds and initiates transcription
- Synthesis of RNA occurs in 5'-3' direction and continuous
- Only a strand of DNA act as template, template is also known as antisense strand or non coding strand
- The complementary strand is the sense strand or the coding strand
- Only a small segment of DNA is transcribed at a time generally called gene
