What is the name of the molecule that brings the amino acids to the
ribosome (purple blob)?

tRNA

Explanation:

When a strand of tRNA has locked onto an amino acid the tRNA is said to be 'charged'. tRNA diffuses into the smaller ribosome sub-unit and each short tRNA strand will deliver ONE amino acid.

Transfer RNA, or tRNA, molecules deliver the amino acids to the ribosome and are also involved in decoding the codons on the messenger RNA.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
