Question

Which flow chart correctly describes steps that lead to the synthesis of proteins?

a
mRNA → tRNA → DNA
b
tRNA → mRNA → DNA
c
mRNA → tRNA → DNA
d
DNA → mRNA → tRNA

Answer 1

The correct flow of information in the synthesis of proteins is described by option **d**:

**DNA → mRNA → tRNA**

1. **DNA** is transcribed to form **mRNA** (messenger RNA).
2. **mRNA** is then translated by **tRNA** (transfer RNA) to synthesize proteins.

So, the sequence of events that leads to protein synthesis is: DNA is transcribed to mRNA, and then mRNA is translated into a protein with the help of tRNA.
