Which transfer RNA molecule is involved in the formation of this part of the sickle cell hemoglobin?
Correct answer: A. tRNA^Val
- A. tRNA^Val
- B. tRNA^Glu
- C. tRNA^Met
- D. tRNA^Lys
Explanation
tRNA^Val is the correct answer. Sickle cell anemia is caused by a single amino acid substitution in the beta-globin chain of hemoglobin from glutamic acid to valine. Therefore, the tRNA that carries valine to the ribosome, tRNA^Val, is involved in the formation of this mutated part of the hemoglobin molecule.

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.
