Question

Why the ribosomes produce or synthesis the proteins?

Answer 1

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts;ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesistakes place); and transfer RNA (tRNA) molecules carry amino acids to theribosomes during protein .

Answer 2

⠀

Ribosomes on RER, which give RER its rough appearance, specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the ER for processing. Proteins synthesized by the RER have specific final destinations, such as the cell membrane, cell exterior, or the ER itself.
