Question

Find out the correct options.
1. Amino acids may have more than one codon
2. All amino acids have more than one codon
3. Codons are common for higher and lower organisms
4. Codons are not found in bacteria

• A.
  $2,4$correct
• B. $1,2$ correct
  
• C. $1,3$ correct
• D. $1,2,3$ correct

Answer 1

The correct option is C $1,3$ correct

Statement 1 :

The property of genetic code, where in an amino acid is coded by more than one codon is called degeneracy. Thus, statement 1 is correct.

Statement 2 :

Not all amino acids are coded by more than one codon. Methionine and Tryptophan have only one codon.Thus, statement 2 is incorrect.

Statement 3 :

The genetic code is universally applicable to all living organisms i.e. from a bacteria to an eukaryote, the codons remain the same. Thus, statement 3 is correct.

Statement 4 :

Codons are found in bacteria and they code for polypeptides. Thus, statement 4 is incorrect.

Final answer:
(D)
