Answer:
4.) This means that height in a rat is controlled by many different genes.
Explanation:
Discovery of structure of DNA by Franklin and Watson and Crick.
Explanation:
Rosalind Franklin was researching about DNA structure at the King’s College at London based on x-ray diffraction studies; while, Crick and Watson were researching on the same at the Cambridge University based on Linus Pauling discovery of proteins.
Once when Watson happen to listen to Franklin’s lecture upon DNA structure and how it depends on relative humidity of the air and other facts relating to DNA; he along with Crick made physical DNA models which became a big failure.
Later, Franklin found that a wet form of DNA with high humidity had a helix like structure. This point became the base of later discovery of Watson and Crick’s double helix model of DNA along with the discovery of DNA molecules being made up of double chain of nucleotides.
Answer: Chemosynthesis
Explanation:hemosynthesis A type of autotrophic nutrition in which organisms (called chemoautotrophs) synthesize organic materials using energy derived from the oxidation of inorganic chemicals, rather than from sunlight.
Opioid receptors interact with G proteins and arrestin. In consequence, opioid receptors interact with protein biomolecules.
<h3>Proteins and opioid receptors</h3>
Proteins are fundamental biomolecules composed of long chains of building blocks called amino acids linked by peptide bonds.
Proteins may have both structural (e.g., components of the cytoskeleton) and enzymatic functions (in this case, activation of signaling pathways).
Opioid receptors interact outside the cell membrane with opioid drugs (e.g., heroin) and with the G proteins inside the cell.
Opioid receptors also interact inside the cell with a special protein that is known as arrestin, thereby activating specific signaling pathways.
