" Identify the codon that codes for the amino acid at sixth position of beta globin chain of normal haemoglobin molecule "

The mRNA codon which codes for the amino acid valine is

Assertion :-Sickle-cell anaemia is caused by the substitutin of glutamic acid by valine at the sixth position of the beat globin chain of the hemoglobin moecule. Reason :- It is due to the single base substatution at the sixth codon of the beta lobin gene from GUG to GAG.

The defect sickle-cell anaemia is caused by the "_____" of glutamic acid by the valine at the 6^(th) position of the "_____" globin chain of the haemoglobin molecule.

The number of codons that code different amino acids is

Sickle cell anaemia is caused by the substitution of Glu by ………... at the sixth position of the beta-globin chain of the hemoglobin molecule.

The defect sickle - cell anaemia is caused by the ________ of glutamic acid by valine at the 6th position of the ________ globin chain of the haemoglobin molecule.

One codon codes for only one amino acid, hence the code is

The number of codons for 20 amino acids are:

In sickle cell anaemia, the sequence of amino acid from first to seventh position of beta -chain of haemoglobin S (HbS) is

Two or more codons coding for one amino acid
