Two hypotheses about how life supporting molecules appeared on earth

Biology
1 answer:
Kay [80]3 years ago
8 0
The two most common hypotheses that theorise the formation of life-supporting molecules on earth would be the Miller-Urey experiment and the meteorite phenomenon. In the meteorite theory, it is said that life on earth began when meteorites containing life-supporting molecules bombarded the planet that eventually caused lifeforms to grow.

How would over expression of protein phosphatase 1 affect the induction of cAMP-inducible genes in response to hormone stimulati
finlep [7]

Answer:

The protein phosphatase-1 dephosphorylates the residues of serine, which are phosphorylated by the protein kinase A. The cyclic-AMP inducible genes are stimulated by CREB that is phosphorylated by protein kinase A. Thus, overexpression of protein phosphatase 1 would prevent their induction.  

Although, protein phosphatase 1 would not influence the function of cAMP-gated ligand channels, as these channels are opened directly by binding of cAMP rather than by protein phosphorylation.

Is this telophase of cytokinesis?
Butoxors [25]
Looking at the inside, it appears so.

In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.

Hope this is correct ^^
