Answer: Option C
Solution (By Examveda Team)
a. Single circular DNA molecule is a bacterial chromosome. A circular chromosome is a chromosome in bacteria, archaea, mitochondria, and chloroplasts, in the form of a molecule of circular DNA, unlike the linear chromosome of most eukaryotes.b. Jacob and Monod proposed the Operon concept. The operon theory was first proposed by the French microbiologists François Jacob and Jacques Monod in the early 1960s.
c. Splicing is the processing of mRNA. RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre-mRNA) transcript is transformed into a mature messenger RNA (mRNA).
d. Growth is an increase in cell number or cell size. Growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volumes.
