<h2>GPCRs,RTKs</h2>
Explanation:
G Protein Coupled Receptors(GPCRs) are more common and found in almost all eukaryotes whereas Receptor Tyrosine Kinases(RTKs) are second largest family of receptors that relay signal from cell surface to the interior
- G protein coupled receptors(GPCRs) interacts with the ligand activated GPCR and phosphorylates its intracellular domain.This process of phosphorylation can terminate signal or desensitize receptor
- Autophosphorylation of receptor can initiate signal in case of Receptor Tyrosine Kinases(RTKs);Autophosphorylation is a feature of RTKs in which receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase
- Seven transmembrane helices can be seen in case of G protein-coupled receptors(GPCRs);transmembrane protein of it consists of single polypeptide and spans the membrane 7 times
- Insulin receptor is a part of Insulin Signalling which comes under RTKs;Insulin receptor always exist in case of dimeric form
- Epinephrine receptor is an example of GPCRs;Epinephrine is an endocrine hormones produced in stress condition
- Transmembrane protein of GPCR activates G protein,activated G protein binds with effector enzyme and activate it;effector enzyme further can produce or destroy secondary messenger

Answer:
The correct answers are options A, C and D.
Explanation:
As sexual reproduction enhances the genetic diversity, thus, the procedure entirely enhances the fitness of the population. The sexual females are only half as associated with their offspring in comparison to the asexual females. This is known as the cost of meiosis, this signifies that there is a dramatic decline in the relatedness in the generation of the out-crossed sexual offspring.
According to the Red Queen hypothesis, parasitism encourages sexual reproduction in the host and an evolutionary trade-off between virulence and transmission.
1. information is transcribed in DNA to mRNA
2. mRNA leaves the nucleus
3. ribosome attaches to the mRNA
4. tRNA anticodon carries an amino acid that compliments the mRNA codon
5. the chain of amino acid forms a protein
