$\alpha$-Amino acids are:

$A$ protein '$X$' with a molecular weight of $70,000 \ u$,on hydrolysis gives amino acids. One of these amino acids is:

The correct zwitter ion structure of glycine is

$\alpha$-helix is found in

$A$ codon has a sequence of $\underline{A}$,and specifies a particular $\underline{B}$ that is to be incorporated into a $\underline{C}$. What are $\underline{A}, \underline{B}, \underline{C}$?
$\underline{A} \quad \underline{B} \quad \underline{C}$

The correct structure of product $P$ in the following reaction is
$Asn-Ser + (excess) (CH_3CO)_2O \xrightarrow{NEt_3} P$
