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.

Where do plants obtain the oxygen necessary to utilize foods? directly from products of photosynthesis from the splitting of wat
IceJOKER [234]

Answer:

from the splitting of water molecule.

Explanation:

The splitting of water molecules  by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis  of enzymes of Photo system 11.

It involves the splitting of water molecules into;

hydrogen ion/protons.

Oxygen

and electron.

<u> Oxygen is  the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.

the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02  to form carbohydrate in light independent reaction
