Select the incorrect statement for the figure given below.
Options
- AThe sequence of amino acids i.e., the positional information in a protein – which is the first amino acid, whi
- BThe first amino acid is also called N-terminal amino acid.
- CThe last amino acid is called the C-terminal amino acid.
- DA protein thread exists throughout as an extended rigid rod.
Correct answer
D. A protein thread exists throughout as an extended rigid rod.
Step-by-step solution
The sequence of amino acids i.e the positional information in a protein – which is the first amino acid, which is second, and so on – is called the primary structure (Figure 9.3 a) of a protein. A protein is imagined as a line, the left end represented by the first amino acid and the right end represented by the last amino acid. The first amino acid is also called N-terminal amino acid. The last amino acid is called the C-terminal amino acid. A protein thread does not exist throughout as an extended rigid rod.
