Answer 1

Answer:

a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Answer 2

Answer:

The ribosome is a complex made of protein and RNA and which adds up to numerous million Daltons in size and assumes an important part in the course of decoding the genetic message reserved in the genome into protein. Ribosomes are macromolecular machines, found within all living cells, that perform biological protein synthesis. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains. Ribosome are like a factory, because ribosomes make proteins like factories make different products. The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate. Ribosomes from various sources (prokaryotes, eukaryotic cytoplasm, mitochondria, chloroplasts, and kinetoplasts) vary in size from 20 to 30 nm in diameter, but all are composed of a large and a small subparticle or subunit and perform similar functions in protein synthesis.
