An elephant of length 4 m is at one corner of a rectangular cage of size (16 m × 30 m) and faces towards the diagonally opposite corner. If the elephant starts moving towards the diagonally opposite corner it takes 15 seconds to reach this corner. Find the speed of the elephant.

Given below, is the result of a complementation test for seven independent mutants (A to G). '+' represents complementation; '_' represents non complementation. Based on the above, which one of the following conclusions is correct

a) The mutations can be ordered in a three cistron as A-G-B-C-D-E-F

b) All mutations belong to a single cistron, but their order cannot be determined.

c) There are three cistrons, mutations A and G represent one cistron, B, C and D represent the second cistron and E and F represents the third cistron.

d) There are three linkage groups, mutations A and G  represent linkage group-I, B, C and D represent linkage group-II, and E and F represents linkage group-III

Q. A researcher is studying a novel gene involved in eye development in Drosophila. They isolate a mutant strain where a single nucleotide insertion has occurred in the first exon of this gene. When a heterozygous fly (one mutant allele, one wild-type allele) is observed, its eyes develop completely normally. Based on the provided principles of genetic mutations, which of the following statements best characterizes this mutation?

Q. A researcher is studying a novel receptor kinase involved in cell signaling. The functionally active form of this receptor is a homodimer that forms at the cell membrane upon ligand binding. The researcher isolates a mutant allele that produces a structurally altered, kinase-dead version of the receptor. When a heterozygous cell line (carrying one normal allele and one mutant allele) is generated, signaling is almost completely abolished, mimicking a null phenotype. Biochemical analysis reveals that the mutant protein is stably expressed and still binds to the normal protein.

which of the following best explains this observation?
