Answer:
D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.
Explanation
In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.
Process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
Answer:
calcitonin
Explanation:
Calcitonin is a hormone which helps in lowering the high blood calcium levels. It is secreted by thyroid glands. Parathyroid glands are responsible for increasing calcium level in the blood while calcitonin hormone work against parathyroid glands and helps in lowering calcium level. Calcitonin hormone inhibit the activity of osteoclasts which are responsible for releasing of calcium from bones into the blood.
sunlight is a reactant in photosynthesis
Answer:
If he or she doesn't look like dad, it might be because he or she hasn't gone through the environmental pressures that will cause the change. If your father's child works outdoors or spends a lot of time outside, there's a good chance that he probably has darker skin than your child.
