To ensure genetic continuity during cellular growth and repair, dna makes exact copies of itself through what process?
a) duplication
b) replication
c) transcription
d) translation

Answer : The correct answer is -

B) Replication.

DNA replication is a mechanism of formation of two DNA molecules by using single molecule of DNA ( which is double stranded).

In this process, two strands of original DNA are first separated and act like template strand, using which enzyme DNA polymerase adds dNTPs ( deoxyribonucleoside triphosphate) in the direction 5' to 3', which is antiparallel to the direction of template strand.

By making exact copy of itself (through replication) , DNA ensures genetic continuity during cell growth and repair.

Thus, option B) is the right answer.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

the answer would be d : p
