What is the function of a ribosome?

A ribosome is a complex cellular mechanism used to translate genetic code into chains of amino acids. Long chains of amino acids fold and function as proteins in cells. The function of a ribosome in any cell is to produce proteins.

What is a pseudobulb?

The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively.

What are membrane-bound ribosomes?

Membrane-bound Ribosomes: when a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become “membrane-bound”. To know more about ribosome, visit Byju’s.

How do the two subunits of the ribosome work together?

The smaller subunit, where the mRNA binds and is decoded, and in the larger subunit, the amino acids get added. Both of the subunits contain both protein and ribonucleic acid components. The two subunits are joined to each other by interactions between the rRNAs in one subunit and proteins in the other subunit.

What is the function of rRNA in ribosome?

Ribosomal RNA (rRNA) molecules are the structural components of the ribosome. The rRNAs form extensive secondary structures and play an active role in recognizing conserved portions of mRNAs and tRNAs. They also assist with the catalysis of protein synthesis.

How do ribosomes Transfer RNA and proteins?

They transfer RNAs (tRNAs) comprising amino acids, and enter into the ribosome at the acceptor site. Once it gets bind up, it adds amino acid to the growing protein chain on tRNA. A ribosome is a complex of RNA and protein and is, therefore, known as a ribonucleoprotein.
