Answer:

One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.

One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.

Answer

RIBOSOMES on the ROUGH ENDOPLASMIC RETICULUM

Explanation:

This is the site of protein synthesis usually find attached to the rough endoplasmic reticulum or  freely on the cystosol,

When they are attached to the  endoplasmic reticulum they appeared as back dots which makes the surface of ER to appear rough, hence the name ROUGH ER. Smooth ER, lacks Ribosomes, and therefore appears smooth,

Ribosomes  are made up of PROTEIN AND RNA.

They are 25nm in diameter;when viewed under high magnification, where theymade up of  two sub-units  the small and large units.

The protein synthesize by the Ribosomes are passed into the sacs  of Rough E.R  for transportation,

Basically, a complete Ribosomes is refereed to as 70S for prokaryotic ribosomes and 80S for Eukaryotic Ribisomes.This refers to their sedimentation Co-efficient in Svedberg units,the Eukaryotes sediment faster than the Prokaroytes
