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.

Why would it be hard to find the ideal CO2 level if the light intensity were very low?
garik1379 [7]
Remember that CO2, light and heat (to activate the reaction and keep the enzymes happy) are all needed for a reaction. When one goes missing, it destroys the whole process.

1. No light = no reaction can be made. That means the plant wouldn't intake any CO2 anyway.

2. When very hot the enzymes will denature (plant dead) or when cold, the activation energy will not be there. So once again, it will not respond to light as it is not its primary concern.
