Second messenger

second messenger

(Science: molecular biology) In many hormone sensitive systems the systemic hormone does not enter the target cell but binds to a receptor and indirectly affects the production of another molecule within the cell, this diffuses intracellularly to the target enzymes or intracellular receptor to produce the response. This intracellular mediator is called the second messenger.

Examples include cyclic AMP, cyclic GMP, iP3 and diacylglycerol.

Does complementary DNA include only coding sequences ?

Hello everyone, I was wondering if complementary DNA is a copy of the entire messenger RNA or only a copy of the coding parts ? I'm really confused... For example, if I have the mRNA of a particular gene with some non-coding parts, will the cDNA be exactly the ...

cAMP 2nd Messenger Pathway and Experiments

... the conversion into cAMP could not occur. E. What is the physiological significance of these results? Why would this be important in the cAMP 2nd messenger system? ---The physiological significance of these results is that the cAMP pathway needs all of these elements present in order to carry ...

BAP, brassinolide, triacontanol, Amino, kelp foliar question

... (beeswax, rice bran wax). There is such test done but it was said that the growth effect has been stimulated before it is inhibited by Octacosanol Messenger. I requested COA of both 30% and 95% purity, both of them show similar amount of Octacosanol. Therefore, I am making an educational guess ...

How did endosymbionts coordinate replication?

... grateful. Originally, they replicated separately, so I'm not sure how they stayed together through generations. Was there some sort of chemical messenger that the mitochondria of a cell received to know it was time to replicate? I don't know. Science help.
