The following figure represents the

Solution
The correct option is A Central dogma
Central dogma
● DNA is the master copy of genetic information and undergoes replication to form new copies of DNA.
● The gene from DNA is converted into mRNA by transcription.
● The RNA is translated into protein by translation.
● This one way flow of genetic information is known as the central dogma of life.
Thus, the figure represents the central dogma.
Lac operon
Lac operon is a genetic system that controls the formation of three enzymes that are needed for lactose metabolism. It comprises a promoter, regulatory genes along with three structural genes named lac Z, lac Y and lac A for the enzymes beta galactosidase, permease and transacetylase, respectively. The regulatory and structural genes are present on the chromosome in a linear fashion and together form an operon.
The given diagram does not represent the lac operon.
Sequence Annotation
Sequence annotation is a method of identifying the sequence of nucleotides in the DNA consisting of both coding and non-coding genes and later assigning the functions to different parts. The figure does not represent sequence annotation.
DNA fingerprinting
DNA fingerprinting is a quick method of comparison of the unique nucleotide sequence of the genome of two individuals. The given diagram does not represent DNA fingerprinting.
Final answer:
(a) Central dogma
