Created by StemPy LabA gene is read from its start codon in triplets. Which statement about mutations and the genetic code is correct?
← All Quizzes
← Match the features of the genetic code in List-I with their meanings in List-II.
List-I (Feature)
A. Nearly universal
B. Degenerate
C. No punctuations
D. Dual function of AUG
List-II (Meaning)
I. The codons are read in mRNA one after another, in a contiguous fashion
II. UUU codes for phenylalanine from bacteria to humans, with some exceptions in mitochondria and some protozoans
III. Some amino acids are coded by more than one codon
IV. It codes for methionine and also acts as the initiator codonAssertion (A): Lactose is called the inducer of the lac operon.
Reason (R): Lactose binds to the operator, and so it stops RNA polymerase from transcribing the operon. →
