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.

So were is the genetic material find in a prokaryotic cell
tiny-mole [99]
Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes 
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion 
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>

What can you conclude about the structure of mitochondria?
rodikova [14]

Answer:

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
