Which mode of transfer does not occur?

a)
dna > rna

b)
rna > protein

c)
dna > protein

d)
mrna > protein

The correct option is C

Explanation:

The central dogma involves conversion of DNA to protein. The DNA either undergoes transcription to form RNA or replication to form a new DNA. When transcription occurs, RNA is formed which can then be translated into protein. Consider the illustration below

DNA ⇒ RNA ⇒ Protein

There are three types of RNA

Of these three RNAs, the mRNA is the one translated into protein with the aid of the remaining two.

From the above, it can be deduced that DNA cannot be directly converted into protein.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
