opposite the anticodon, extends a three nucleotide acceptor site that includes a free -OH group. A specific tRNA binds to a specific amino acid through its acceptor stem.
The relaxed form of DNA in a cell's nucleus is called chromatin.
<h3>CHROMATIN:</h3>
- Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones.
- This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.
Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

Answer:
Median height is selected
Explanation:
Stabilizing selection is a particular type of natural selection where the mean of the trait in the population stabilizes on non-extreme phenotypes, thereby favoring intermediate phenotypic variants. At genetic level, stabilizing selection is shaped by selective forces that push the distribution of the trait in the population toward the average (median trait), it is a condition that may happen when a population is completely adapted to its environment. Thus, stabilizing selection acts to purge the extreme phenotypic variants via purifying selection. Stabilizing selection is considered to be one of the most important mechanisms controlling the distribution of different phenotypes after many cycles of artificial selection, it s for that reason that breeders believe that this type of natural selection is the most common in nature.
