NEET BIOLOGY

Detailed explanation-1: -Complete answer: Ribosomes are composed of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotic cells, ribosomes are nearly 40% protein and 60% rRNA.

Detailed explanation-2: -Sc. Reviewed by Michael Greenwood, M.Sc. RNA or ribonucleic acid is a polymer of nucleotides that is made up of a ribose sugar, a phosphate, and bases such as adenine, guanine, cytosine, and uracil.

Detailed explanation-3: -The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.

Detailed explanation-4: -Complete answer: The 50S ribosomal subunit has 23S rRNA and a 5s rRNA with 32 different proteins. Along with the 30S subunit, the 50S Ribosome consists of the 70S type of ribosome present in prokaryotic cells as well as mitochondria and chloroplast of the eukaryotic cells.

Detailed explanation-5: -Ribosomes are composed of two subunits, the large and the small subunit, both of which consist of ribosomal RNA (rRNA) molecules and a variable number of ribosomal proteins. Several factor proteins catalyze different steps of protein synthesis by binding transiently to the ribosome.
