Cech and Altman discovered the self-replication and biocatalytic properties of RNA. Option B.

<h3>What did Cech and Altman discover?</h3>

After several years of research, Cech and Altman discovered that, apart from being inheritable molecules and being involved in protein synthesis, RNA functions as a biocatalyst -just like enzymes- .

These scientists discovered that RNA shares with DNA the capability of transmitting genetic information and with proteins the capability of facilitating chemical reactions as a biocatalyst.

They could prove that,

  • RNA can self-replicate because it carries the genetic information needed to do it and <u>does not need </u>other proteins.
  • It has a significant protagonism in cellular metabolism.

In the enzyme's and additional energy absence, the molecule can start its maturation process, catalyzing reactions by itself. Cech named this RNA form with enzymatic function ribozyme.

This was a significant discovery since it demonstrated that not only proteins were involved in biological reactions.

The essential molecule __________ comprises over 60 percent of any living organism's cells.
Debora [2.8K]
The essential molecule that comprises an average of 60% of any living organisms' cells is water. Water is a molecule made up of two hydrogen atoms and one oxygen atom. Water is an essential part that makes up the matrix of the inside and outside membranes of, for example, tissues in the human body. Water, to a certain degree, also helps maintain balance of electrolytes and solutes that go in and out of the cell. It also maintains hydrostatic pressure in the circulatory system of the body via the balance of Starling Forces. These are just a few examples of the importance of water and hence why living things need so much of them. This is also why water is one of the first things astronauts look for in planets to determine if life is possible there or if there was life before.

Other important elements that make living things are nitrogen (N) and calcium (Ca). To serve as a reference point, we can look at the human body. The amount of nitrogen (N) in the body is about 3.2%. Calcium (Ca) on the other hand, is about 1.5%
