After the adenylyl cyclase reaction (which convert ATP into cyclic adenosine monophosphate-cAMP), cAMP level is directly increased. Next steps of PKA activation include:
• cAMP binding to regulatory subunits of PKA, as a result conformational change in the regulatory subunits of PKA is induced,
• catalytic subunits are detached and unleashed by regulatory subunits and as a result activated.
The answer for this question would be the second option. Genomic studies cover the analysis of the changes of genome by scanning the markers across complete sets of DNA. Based on these studies, the change in gene sequences happen that resulted to a change in the way that the brain interprets speech in between 4 and 9 million years ago.
Answer:
true
