Kinases. Kinases add phosphate to molecules, and the modification can serve as a "switch" to turn events in the cell on or off. CDKs or cyclin dependent kinases regulate the cell cycle.
Because electrons are “pulled” towards the oxygen.
Answer:
Option (d).
Explanation:
Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.
Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.
Thus, the correct answer is option (d).
A. Amber, because in the Prehistoric times the insects and small dinosaurs fell into amber and became preserved in the hardened sap.
