Question

What is the ribosome? What are the 2 partfs of it? What are the three spots on the ribosome that tRNA can bind to

Answer 1

A ribosome is a cellular organelle involved in protein synthesis. It has two parts: a large subunit and a small subunit. There are three spots on the ribosome that tRNA can bind to: the A site, P site, and E site.

Step-by-step explanation:

A ribosome is a cellular organelle involved in protein synthesis. It consists of two parts: a large subunit and a small subunit. The mRNA molecule sits in between these two subunits. Three spots on the ribosome that tRNA can bind to are:

1. The A site (aminoacyl site): where the incoming charged tRNA brings the next amino acid to be added to the growing polypeptide chain.
2. The P site (peptidyl site): where the tRNA holds the peptidyl-tRNA, which carries the nascent polypeptide chain.
3. The E site (exit site): where the tRNA that has released its amino acid exits the ribosome.
