Numerous Xenopus cells were exposed to varying amounts of ultraviolet light.Some of the resulting cells were observed to lack nucleoli.As a result,one would expect that the cell could not
A)perform cellular respiration.
B)replicate its DNA.
C)perform photosynthesis.
D)synthesize ribosomal RNA.
E)perform cellular respiration or replicate its DNA.

Question

Quizplus · Accepted Answer

Nucleoli are involved in the synthesis of ribosomal RNA (rRNA), which is crucial for ribosome assembly and protein synthesis. Lack of nucleoli would impair the cell's ability to synthesize rRNA, affecting protein synthesis but not directly impacting cellular respiration, DNA replication, or photosynthesis (which does not occur in animal cells like Xenopus).
