hnRNA undergoes two additional processes. Out of them in one process an unusual nucleotide (methyl GPT) is added to the 5' end of the molecule. What would you call this?

• Tailing

• Splicing

• Termination

• Capping

Variation in gene frequencies within a population can occur by chance rather than by natural selection. This is referred to as

• Genetic flow

• Genetic drift

• Random mating

• Genetic load
