Granular bodies in the cytoplasm, released from their initial positions on the rough endoplasmic reticulum, that copy the information in segments of dna to provide instruction for the construction of proteins is

Ribosomes

Explanation:

Ribosomes are the bodies which are present in the cytosol either in free form or attached to an organelle called the endoplasmic reticulum.

The ribosome units are composed of rRNA and RNA proteins which form two subunits of the ribosomes.

The ribosomes are specialised for the synthesis of proteins from the mRNA molecule by reading the RNA bases in codon or triplets forms.

Since in the given situation the granular bodies are attached to the endoplasmic reticulum which forms proteins therefore its is indicating that ribosome is the correct answer.

Thus, ribosomes are the correct answer.
