Identify the correct features of the genetic code. i. It is a triplet code. ii. It shows distinct polarity. iii. It is overlapping. iv. The genetic code was deciphered by Watson and Crick.

Options

  1. AAll correct
  2. BStatement (i) and Statement (ii) are correct.
  3. CStatement (iii) and (iv) are correct
  4. DAll wrong

Correct answer

B. Statement (i) and Statement (ii) are correct.

Step-by-step solution

The genetic code is a triplet code, meaning three nitrogenous bases code for one amino acid. It has a distinct polarity and is always read in the 5' 3' direction on the mRNA. The genetic code is non-overlapping, meaning each base is part of only one codon. The genetic code was deciphered by Marshall Nirenberg, Heinrich Matthaei, and Har Gobind Khorana, not by Watson and Crick. Watson and Crick proposed the double-helical structure of DNA. Thus, statements (i) and (ii) are correct. Answer: Statement (i) and Statemen
