In a polypeptide or a protein, amino acids are linked by a bond which is formed when the _______group of one amino acid reacts with the ________group of the next amino acid.
1 Carboxyl (-COOH), hydrogen
2 Amino (-\(N{H_2}\)), amino (-\(N{H_2}\))
3 Carboxyl (-COOH), amino (-\(N{H_2}\))
4 Amino (-\(N{H_2}\)), carboxyl (-COOH)
Explanation:
In a polypeptide or a protein, amino acids are linked by a peptide bond which is formed when the carboxyl (-COOH) group of one amino acid reacts with the amino (-\(N{H_2}\) ) group of the next amino acid

The form of DNA with 34Å pitch with a rise per base pair of 3.4Å is called
1 A-DNA
2 Z-DNA
3 B-DNA
4 C-DNA
Explanation:
In one form of DNA, each DNA strand appears like a helical straircase and each step of ascent is represented by a pair of bases. At each ascent step, the pitch would be \(34\;\mathop A\limits^ \circ \) and the rise per base pair would be \(34\;\mathop A\limits^ \circ \) . This form of DNA is called the B-DNA.
