Lampbrush chromosomes are found inside _______?
Correct answer: C. Oocytes of frog
- A. Salvary glands of Drosophila
- B. Salvary gland of silk moth
- C. Oocytes of frog
- D. Nucleus of man
Explanation
Lampbrush chromosomes occur in the oocytes of frogs and other vertebrates, where their extended loops support intense RNA production during egg development. The salivary glands of Drosophila contain polytene chromosomes, not lampbrush chromosomes, so that option is a common mix-up.
