Biology Question on the molecular basis of inheritance
m-RNA is synthesised on DNA template in which direction
A
5' ?'
B
3' ?'
C
both a and b
D
any.
Answer
5' ?'
Explanation
Solution
mRNA is synthesized on DNA template in 5' - 3' direction. Synthesis of mRNA exhibits several features that are synonymous with DNA replication. RNA synthes ais requires accurate and efficient initiation, elongation proceeds in the 5' - 3' direction (i.e. the polymerase oves along the template strand of DNA in the 5' - 3' direction), and RNA synthesis requires distinct and accurate termination. Transcription exhibits several features that are distinct from replication.
