Read the code mentioned in the following picture and arrange the sequence of all five codons in which Leucine is at 3rd position. while isoleucine is in 4th position. Keep in mind that CUU is the code for Leucine, AUU for Isoleucine and CAA or glutamine.
Correct answer: B. AUG-CAA-CUU-AUU-UAA
- A. UAA-AUG-CAA-CUU-AUU
- B. AUG-CAA-CUU-AUU-UAA
- C. AUU-AUG.CAA.CUU-UAA
- D. AUG-UAA -CUU-AUU.CAA
Explanation
AUG-CAA-CUU-AUU-UAA is most appropriate because it starts with a start codon and ends with a stop codon while having CUU and AUU at third and fourth positions respectively.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
