Homework Answers
1) this is called signal transduction because a signal which may be electrical or chemical bound to receptors present in cell membrane or cytoplasm or nucleus and which then results in the activation of second messenger and which perform many function and which Function is also be amplified.
As signal is transmitted from one Molecules to next , it is called signal transduction
2) Alternating splicing make many protein of different size from single mRNA because in this procedure different introns are deleted and different Econs get attached and thus different protein is synthesized.

1-1. You wish to insert a gene involved in the degradation of a toxic compound into a plasmid, and then use the plasmid as a vector to transform a species of bacteria so that it can be used in a bioremediation effort to clean up hazardous waste. In order to accomplish this, you will need to ______. SELECT ALL THAT APPLY. -digest both the gene and plasmid with the same restriction enzymes in order to yield appropriate "sticky ends" that...

Release of acetylcholine from a neuron onto a striated muscle cell triggers contraction, release onto a heart muscle slows the rate of contraction, and release onto a pancreatic acinar cell triggers the release of digestive enzymes. How can acetylcholine have different effects on different cells? Different subtypes of the acetylcholine receptor activate different signal transduction pathways in different cells. Acetylcholine binds to intracellular receptors in some cell types, tyrosine kinase receptors in other cell types, and G protein-coupled receptors in...
