The codon for anticodon $3^{\prime}$-UUUA- $5^{\prime}$ is

  • A
    $3^{\prime}-\mathrm{AAU}-5^{\prime}$
  • B
    $5^{\prime}$-UAAA- $3^{\prime}$
  • Correct answer
    C
    $5^{\prime}$-AAAU-3'
  • D
    $3^{\prime}-U A A U-5^{\prime}$

Solution

In RNA the thymine of DNA is replaced by uracil. Codon and anticodon both found on RNA and are complementary to each other so, the codon for anticodon $3^{\prime}$-UUUA-5' will be $5^{\prime}$-AAUU- $3^{\prime}$.

Hence, the correct answer is option: 'C'.
