Answer:
Cell signaling involves three stages that are reception of signal molecules by the cell surface receptor, transduction of that signal molecules and response of the signal molecule.
Reception: In reception, the items that are involved are receptor molecules and cell surface receptors like G- protein-coupled receptors, receptor tyrosine kinase, enzyme-linked receptors.
Transduction: In transduction, the items involved are adenylyl cyclase, phosphorylation cascade, second messenger like cAMP, DAG and IP3.
Response: The response of cell signaling is the starting of molecular processes and the production of proteins.
Answer:
The cuts are that are made by endonucleases have two outcome. Either they will be of sticky ends or blunt ends. Both of these ends come as a result of type of endonuclease that we are going to use.
There are also some extra sequence fragments that came additionally after cutting procedure. For example, the endonuclease EcoR1 cut the DNA fragments from 5' end that are sticky in nature and extra fragments of AATT hang up after cutting.
I believe the answer is A.
The answer is a<span> haploid cell formed in the female ovary.
A human egg cell is actually gamete cell. It is known that gamete cells are produced in the process of meiosis and, thus, they are haploid. So, a human egg cell must be haploid. Gametes are produced in gonads, which can be either female ovary or male testes. Females have ovary which produces egg cells.</span>
