Question

How does the structure of DNA allow :

-DNA to replicate itself?

-DNA to carry coded messages

-The message on the DNA to undergo mutation

And why is it important that DNA has this property

Please help:) Thanks

Answer 1

The 3-D shape of biological molecules is crucial for the

molecules to perform certain chemical reaction because the 3-D shape forms tunnels, cavities or grooves that are suited for holding other molecules in place long enough to cause certain important reactions to occur. The backbone

of the self-replicating peptide has what appears to be an essentially 1-D straight shape this is what allows it to self-replicate.

DNA is not rigid therefore it is less costly both energetically

and spatially to use as the storage material. DNA is more consistant and not really diverse helping it to carry messages.
