A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: B
Solution :
Amino acids form peptide bonds between each other and ultimately proteins are formed. \[R-\underset{N{{H}_{3}}}{\mathop{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}\,C}}\,O\begin{matrix} OH+H \\ \end{matrix}\overset{{{H}_{2}}}{\mathop{\overset{|}{\mathop{N}}\,-}}\,\underset{H}{\overset{R}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-COOH\] \[\to R-\underset{N{{H}_{3}}}{\mathop{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}\,-}}\,\underset{\text{Peptide bond}}{\mathop{\begin{matrix} CON{{H}_{2}} \\ \end{matrix}}}\,-\underset{H}{\overset{R}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-COOH\] The smallest protein is adrenocorticotrophic hormone or ACTH. It has a molecular weight of 4500 daltons and contains 39 amino acids
