Answer #1

Answer. Point mutation.

Haemoglobin possess a tertiary structure because of its 4 polypeptides. A normal quaternary structure of haemoglobin gives RBC biconcave shape.

However, when a single mutation in DNA changes GAG to GTG, changes the hydrophilic amino acid glutamic acid to the hydrophobic valine.

As the a single base A is changed to T, thus this mutation is called a point mutation.

This disrupts the normal structure of haemoglobin and which makes RBCs sickle shaped.

Gene X encodes protein X, which normally functions as a transcription factor, regulating the expression of certain genes. A particular mutant allele of gene X is created by a frameshift mutation; the protein encoded by this mutation has kinase activity, meaning it acts as an enzyme that phosphorylates other proteins. This mutation is an example of A. a gain-of-function mutation. B. a loss-of-function mutation. C. a neomorphic mutation. A and C B and C

Which of the following is NOT true of the Drosophila bicoid gene? The bicoid gene encodes an mRNA that is deposited into the egg by the mother and is localized in one end of the egg. The bicoid mRNA is translated to Bicoid protein after the egg is fertilized. The bicoid gene encodes a protein that specifies the anterior end of the embryo. The bicoid gene is considered to be a cytoplasmic polarity gene. none of the above (i.e. all...

The wildtype allele of the SYN gene encodes a protein product that stimulates the synthesis of carotenoid pigment in plant leaves. The wildtype homozygote would have 20 units of SYN enzyme and 200ppm (parts per million) carotenoids in its leaves. A mutant for this gene is found which, in the homozygote, produces 20 units of SYN enzyme and 125 ppm carotenoids. The pure-breeding strains are crossed and the F1 produces 20 units of SYN enzyme and 180 ppm carotenoids. The...
