class 12th CBSE Biology sample paper

Answer 1

The proposition of a double helix structure for DNA and its simplicity in explaining the genetic implication became revolutionary. Very soon, Francis Crick proposed the Central dogma in molecular biology, which states that the genetic information flows from DNA→RNA→Protein.

.

This means that the DNA is coded into a type of RNA(mRNA) which is used in protein formation.

In some viruses for example Retro-virus a process called reverse central dogma is performed in which the RNA genome of virus is processed into DNA.
