Question

Which of the following is correct about
ribosome except
Site of protein synthesis
Universal cell organelle
70s ribosomal units
80s ribosomal units​

Answer 1

Ribosomes (/ˈraɪbəˌsoʊm, -boʊ-/[1]) are macromolecular machines, found within all living cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).[2][3][4] The ribosomes and associated molecules are also known as the translational apparatus.

Answer 2

Answer:

all are true

Explanation:

Ribosomes are cell organelles that are formed of two subunits. Cytosolic, eukaryotic ribosomes (80S) are made up of 60S and 40S subunits, while prokaryotic ribosomes (70S) are made up of 50S and 30S subunits.

They are also capable of forming polyribosomes during which many ribosomes are attached to mRNA. The purpose of ribosomes moving on mRNA is to synthesise proteins i.e., translation. Indeed, ribosomes have a very direct role in protein synthesis.
