Answer #1

1. mRNA is processed before it is translated is most true of RNA because, When gene gets transcribed in the transcript it is generally doesn't considered as mature mRNA it is called pre-mRNA.

2. This transcript or pre-mRNA has to go some modifications to convert into mature mRNA.

3. The modifications include -

a. Splicing,

b. 5' capping,

c. 3' addition of poly-A tail.

These modifications protect the mRNA while transporting from nucleus to cytoplasm where translation starts.
