Replacement of which one of the following nucleotides in the \(\mathbf{H b}^{\mathrm{g}}\) gene causes sickle cell anaemia?
1 A to T
2 T to A
3 U to A
4 \(C\) to \(G\)
Explanation:
: Point mutation in the beta globin gene produces haemoglobin's which makes the erythrocytes bend or sickle. This is due to a point mutation which is a substitution of a single Aderine (A) meleotide for a thymine macleotide converting a codon for glutamic acid-GAG-to one for valine- GTG. This is a switch of a purine for a pyrimidin base and is therefore a transversion rutation.

The gene of sickle cell anaemia is inherited by
1 blood cells
2 bone cells
3 sex chromosomes
4 autosomes
Explanation:
: Sicklecell anaemia is a hereditary disorder of autosomal nature which is caused by mutation of the gene controlling \(\beta\)-chain of haemoglobin.

2n-2 is hnown as:
1 monosomic
2 trisomic
3 mullisonyy
4 polyploidy
Explanation:
: An organism that has lost a chromosome pair is called mullisomic. The result is usually lethal to售loids ( \(2 \mathrm{n}-2\) ).
