A Ribosome is composed of ribosomal RNA and proteins.
They are made in the cell nucleus, in two types of subunits, the large and the small.
The subunits go to the cell body, where they can float free in the cytoplasm or attach to the rough endoplasmic reticulum.
Epistasis is the phenomenon where one pair of gene interacts
with a second pair to control its expression by masking, suppressing or
modifying it. <span>The
term meant that a different gene masks the phenotypic effect of another gene. Moreover,
epistasis has a large influence on the evolution of phenotypic traits. </span>
