The answer is 100%. Three are observable, but the fourth is just a carrier.
PZ120 is not considered to be an enhancer to transcription in the metallothionein 2a gene.
<h3>About metallothionein 2A.</h3>
Metallothionein-2 is a metallothionein protein that in humans is encoded by the MT2A gene.
In human it is expressed in;

Answer:
A and D
Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.
If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:
- Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
- The normal synthetase might be present but not in an adequate amount.
Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
