One way is runoff, I forgot the other
So the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set
<h2>GPCRs and RTKs</h2>
Explanation:
1) Phosphorylation of receptor can terminate signal or desensitize receptor: GPCRs because when signal persists a protein kinase receptor is activated,this further catalyse the phosphorylation of several serine residue at cytosolic phase of 7 transmembrane
Phosphorylated transmembrane recognized by arrestin protein blocks interaction between trimeric G protein and receptor thus blocks signal transduction
2) Autophosphorylation of receptor can initiate signal: RTKs because receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase
3) Structure contains seven transmembrane helices: GPCRs because it consists of single polypeptide and spans the membrane 7 times hence called 7 transmembrane;it recognizes external signal and activates trimeric G protein
4) Ligand binding induces conformational change in receptor: RTKs because normally RTK exist in monomeric form in absence of any ligand molecule but when any ligand molecule binds receptor starts to dimerize
5) Receptor activation causes phosphorylation of its cytosolic subunits: RTKs because when receptor gets activates the intrinsic tyrosine kinase activity by which they phosphorylate its cytosolic subunits
6) An example is the insulin receptor: Insulin receptor is present on plasma membrane and belongs to RTK family and always exist in dimeric form
7) Transports some ligands through the membrane: Neither GPCR nor RTK;ligand gets transported through the membrane through ligand gated channel
8) An example is the epinephrine receptor: Epinephrine is an endocrine hormone produced by adrenal glands in stress condition and prepare body for fight and flight;Epinephrine uses GPCR signalling pathway by four different types of membrane receptors in different tissues
9) Activate heterotrimeric G proteins directly: Transmembrane protein of GPCR recognizes the external signal and activates G protein,activated G protein binds with effector enzyme and activate it which further produce or destroy secondary messenger that carry message from cell surface to cell interior
<h2>Multimale Primates Group</h2>
Explanation:
- Multi-male group, otherwise called multi-male/multi-female, are a sort of social association wherein a gathering comprises of more than one grown-up male, more than one grown-up female, and posterity everything being equal. Inside Order Primates, it is the most widely recognized social gathering type, with bunch sizes going from 10 to 100 people made out of a few guys, and various females and posterity. Huge gatherings of primates are classified "troops" which are described by complex intratroop governmental issues and rivalry. Inside soldiers, there are no steady hetero bonds—the two guys and females have various mates
- Multi-male group are generally regular among semi-earthly primates, for example, savanna mandrills, macaques, langurs, and other new world monkey species just as chimpanzees, gorillas, and other old world primates (cercopithecine) A few animal types, for example, the leptodactylid frog and numerous rat species, for example, the prairie vole have additionally been known to have multi-male/multi-female etc
