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.

Answer:
The correct answer is D.) genetic drift
Explanation:
Genetic drift refers to a population's unpredictable oscillations in the number of gene variants. When the occurrence of various forms of a gene, known as alleles, increases and decreases by chance over time, this is known as genetic drift. The changes in allele frequencies are used to measure these differences in allele presence. I hope this helps! ^-^
