Question

RNA plays important roles in many cellular processes, particularly those associated with protein synthesis: transcription, RNA processing, and translation.

Drag the labels to the appropriate bins to identify the step in protein synthesis where each type of RNA first plays a role. If an RNA does not play a role in protein synthesis, drag it to the "not used in protein synthesis" bin.
1. transcription/RNA processing
2. translation
3. not used in protein synthesis
a) snRNA
b) tRNA
c) mRNA
d) RNA primers
e) pre-mRNA
f) rRNA

Answer 1

Answer:

1. transcription/RNA processing:

a) snRNA

c) mRNA

e) pre-mRNA

2. translation

b) tRNA

f) rRNA

3. not used in protein synthesis

d) RNA primers

The snRNA are involved in the splicing of the RNA molecules hence, they are involved in RNA splicing. The pre-mRNA makes the mature RNA which is ready to travel from the nucleus. The mRNA is made as a result of transciption. Hence, all these options go with transcription/RNA processing.

During translation, the tRNA brings nucleotides so that an amino acid chain can be formed. As rRNA are present in the ribosomes hence tRNA nd rRna are parts of translation machinery.
