Map EA Sapling Learning There are two types of nucleic acids, DNA and RNA. Nearly all
organisms use DNA, not RNA, as the central repository for genetic information. Choose the
statements that explain this phenomenon. DNA has a double-stranded structure that ensures an
accurate mechanism of duplication. DNA contains guanine as one of its nitrogenous bases DNA
is more resistant against enzymes that break down nucleic acids. DNA contains a hydroxyl group
at the 2\' carbon. DNA is flexible and forms complex catalytic structures.
Solution
DNA has double stranded structure that ensures an accurate mechanism of duplication.
A moecuele that can act as a genetic material is expected to fulfill the following criteria....
REPLICTION- it should have the ability to replicate itself.
STABILITY- it should provide a stability storage for genetic information.
EVOLUTION-it should have the ability to evolve and change itself
EXPRESSION-It should be able to express the information when needed.
In RNA .... There is no complementary base pairing for replication. So RNA cant perform
replication.
Whenever genetic information passing from generation to generation it needs stabilty. In RNA,
at 2\' position there is presence of OH group. And intead of Thymine there is presence of
URACIL. These two things makes RNA unstable.
For evolution there is needof Nucleic acid wich shows slow and gradual change. DNA shows
slowand gradual chamge but RNA shows mutations faster because it is unstable.
Due to these reasons DNA accurate for duplication and evolution than RNA..
