Question

Units of marker used in creation of three domains are

• A. Amino acids
• B. DNA
• C. 16S rRNA
• D. Monosaccharides

Hint:

The three domains are \[ \boxed{\text{Archaea, Bacteria and Eukarya}} \] and are classified using \[ \boxed{\text{16S rRNA sequence analysis}.} \]

Answer 1

The Correct Option is C

Step 1: Recall the three-domain classification. The three-domain system of classification proposed by Carl Woese is based on the comparison of \[ \boxed{\text{16S rRNA sequences}.} \] These sequences serve as molecular markers for determining evolutionary relationships among organisms.

Step 2: Choose the correct option. Hence, \[ \boxed{\text{16S rRNA}} \] is the molecular marker used in the creation of the three domains. Therefore, the correct option is \(\boxed{(C)}\).
