Ribosome

This is required by all living cells and associated viruses. The sequence of DNA encoding for a protein may be copied many times into messenger RNA (mRNA) chains of a similar sequence. Ribosomes can bind to an mRNA chain and use it as a template for determining the correct sequence of amino acids in a particular protein. Amino acids are selected, collected and carried to the ribosome by transfer RNA (tRNA molecules), which enter one part of the ribosome and bind to the messenger RNA chain. The attached amino acids are then linked together by another part of the ribosome. Cell (biology) The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional and biological unit of all known living organisms.

Cell (biology)

Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". The study of cells is called cell biology. The cell was discovered by Robert Hooke in 1665. Prokaryotes, Eukaryotes, & Viruses Tutorial. Prokaryotes, Eukaryotes, & Viruses Tutorial. Prokaryotes, Eukaryotes, & Viruses Tutorial.
