Question

In eukaryotic cells, the processes of protein synthesis occur in different cellular locations.Drag the labels to the appropriate targets to identify where in the cell each process associated with protein synthesis takes place.

1. nucleus-->2. cytoplasm--->3. free ribosomes--->4. chromatin--->5. ribosomes--->

Answer 1

1. nucleus- formation of ribosomal subunit

2. cytoplasm- attachment of amino acid to tRNA.

3. free ribosomes- cytoplasmic protein synthesis

4. chromatin- transcription and RNA processing

5. ribosomes: secretory protein synthesis

Explanation:

The nucleolus is the place in the nucleus where the ribosomal proteins enter and combine to form two ribosomal subunits. Therefore ribosomes are formed in the nucleus.

In the cytoplasm, free ribosomes are present which synthesize cytoplasmic protein and in the cytoplasm, amino acids attach to tRNA molecules and make aminoacyl tRNA which helps in making protein during translation.

Chromatin which is less condensed are transcribed in the nucleus into mRNA and this mRNA goes through RNA processing for mature mRNA.

Ribosomes are also attached with RER which is responsible for the production of secretory proteins that moves out of the cell.
