The animal that exhibits 'canine' teeth adapted for tearing flesh is characteristic of:
A. Omnivores
B. Detritivores
C. Carnivores
D. Herbivores
Answer: Option C
Solution (By JKExamLibrary)
Carnivores have well-developed, sharp, pointed canines for piercing and tearing flesh. Herbivores have reduced or absent canines, with well-developed molars for grinding. Omnivores like humans have moderate canines. Detritivores feed on detritus. Dental formula and tooth type are adaptations to diet. Dogs, cats, and lions have prominent canines.

Question #1
The enzyme used to join DNA fragments in genetic engineering is:
A. DNA polymerase
B. DNA ligase
C. Restriction enzyme
D. Helicase

Correct Answer: Option B


Explanation:
DNA ligase seals the phosphodiester bonds between adjacent DNA fragments, joining them together. In recombinant DNA technology, it is used to ligate the gene of interest into a vector. Restriction enzymes cut DNA, DNA polymerase synthesizes DNA, and helicase unwinds the double helix. Ligase is essential for finalizing the recombinant DNA molecule.
