Ribosome The ribosome (/ˈraɪbɵˌzoʊm/) is a large and complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.rokaryotes have 70 S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Their small subunit has a 16S RNA subunit (consisting of 1540 nucleotides) bound to 21 proteins. The large subunit is composed of a 5S RNA subunit (120 nucleotides), a 23S RNA subunit (2900 nucleotides) and 31 proteins.

Hammerhead ribozyme The hammerhead ribozyme is a RNA molecule motif that catalyzes reversible cleavage and joining reactions at a specific site within an RNA molecule.he hammerhead ribozyme carries out a very simple chemical reaction that results in the breakage of the substrate strand of RNA, specifically at C17, the cleavage-site nucleotide. Although RNA cleavage is often referred to as hydrolysis, the mechanism employed does not in fact involve the addition of water.

What is Ribozyme? A ribozyme (from ribonucleic acid enzyme, also called RNA enzyme or catalytic RNA) is an RNA molecule that catalyzes a chemical reaction.Many natural ribozymes catalyze either their own cleavage or the cleavage of other RNAs, but they have also been found to catalyze the aminotransferase activity of the ribosome.he biggest problem is that the cell is producing a large number of RNAs from a huge number of different genes. Obviously when the ribozyme is introduced into the cell, the researcher does not want the ribozyme to cut all the RNA messengers since a large number of genes will be turned off.

The Ribosome The Ribosome. Ribosomes are ancient molecular machines that are responsible for production of protein in all living cells. They are large (2.5 MD molecular weight or larger) macromolecular complexes composed of RNA (2/3) and protein (1/3).ibosomes read the nucleotide sequence of a messenger RNA (mRNA) into a protein sequence, using the genetic code. They use transfer RNAs (tRNAs) to mediate this process of translation from the nucleotide language of RNA and DNA into the amino acid language of proteins.

It is made up of dozens of distinct proteins (the exact number varies a little bit between species) as well as a few specialized RNA molecules known as ribosomal RNA (rRNA). Note – these rRNAs do not carry instructions to make specific proteins like mRNAs.

Lysozyme Lysozyme. Lysozyme is an enzyme found in both tears and saliva. Each time we blink our eyes, our eyelids wash tears over the surface of our eyes. And our mouth is continually producing saliva. The enzyme lysozyme breaks down bacterial cell walls, which are made of a unique compound called peptidoglycan.
