Which of the following regarding the basic mechanism of gene expression is correct?

Question

a
RNA ―> DNA ―> mRNA ―> protein
b
DNA ―> protein ―> RNA
c
RNA ―> DNA ―> tRNA ―> protein
d
DNA ―> RNA ―> protein

Answer 1

The correct answer regarding the basic mechanism of gene expression is:

d. DNA → RNA → protein

This process is known as the central dogma of molecular biology, describing the flow of genetic information within a biological system. Here, DNA is transcribed into RNA (specifically mRNA), which is then translated into protein.
