Question

Examination of a cell by transmission electron microscopy reveals a high density of ribosomes in the cytoplasm. This observation suggests that this cell is actively producing large amounts of what molecules?

Answer 1

While examining a cell under transmission electron microscope, it is observed that the high density of ribosomes present in the cytoplasm produces large amounts or protein molecules. Ribosome contains rRNA and proteins. rRNA directs the catalytic process of protein synthesis.

The messenger RNA or mRNA that have the coding sequences exits from the nucleus and enters the ribosome and gets translated to form proteins. The transfer RNA or tRNA relocates amino acids from nucleus to the ribosome.
