Assertion : Comparative biochemistry provides a strong evidence in favour of common ancestry of living beings.
Reason : Genetic code is universal

If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

If both Assertion and Reason are true but the Reason is not the correct explanation of the assertion

If Assertion is true but Reason is false

If both Assertion and Reason are false

Solution

If both Assertion and Reason are true but the Reason is not the correct explanation of the assertion

Convincing evidence of common ancestry comes from the similarities in the biochemical composition, reactions and physiological activities of living beings, like metabolic process, enzymes. cytochrome C, insulin, haemoglobin, blood and lymph etc.

Genetic code is the sequence of DNA nucleotides that determines the amino acid sequence of the translated protein. It is read in triplets of bases called codons. It is applicable universally i.e. a codon specifies the same amino acid from a virus to a tree or human beings. The mRNA from chick oviduct introduced in E.coli produces an ovalbumen in the bacterium exactly similar to one formed in chick.
