The enzyme that removes RNA primers during DNA replication is: MCQ with Answer and Explanation

Explanation:
Mitochondria and chloroplasts contain circular DNA and 70S ribosomes, enabling them to transcribe and translate some proteins independently, though they rely on nuclear genes for most proteins. This partial autonomy supports the endosymbiotic origin hypothesis. The presence of their own genetic material and protein synthesis machinery qualifies them as semi-autonomous. Thus, both assertion and reason are correct, and the reason correctly explains the assertion.

Explanation:
DNA replication is semi-conservative, meaning each new DNA molecule contains one original parental strand and one newly synthesized strand. Transcription, the synthesis of mRNA from a DNA template, occurs in the nucleus of eukaryotes, not the cytoplasm. Translation, the synthesis of proteins from mRNA, occurs at ribosomes in the cytoplasm or on the rough ER. Thus, statements 1 and 3 are correct.

Explanation:
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.
