14) when the progeny of two mutants shows normal phenotype, mutations in the parents are in different genes so that the hybrid gets a normal copy of both genes, if the progeny of two mutants shows mutant phenotype then parents have mutations on the same gene.
two mutants are said to be complementing when progeny has wildtype phenotype.
1,4 and 5 does not complement each other.
2 complements with all others.
3 complements with all others.
so there are three genes
gene A-1,4,5 are alleles
gene B- 2 is the allele
gene C- 3 is the allele
so the answer is C) 3 genes.
15) the DNA polymerase adds new nucleotides to the 3`-OH of the existing nucleic acid, so the direction of DNA synthesis is 5` to 3` so the answer is A) 5` to 3`
16) during S phase DNA replication occurs, DNA is replicated, DNA replication is semiconservative so the answer is B) double helix replicated semiconservatively.
14..........In Neurospora (a fungus), a complementation test was performed on tive haploid mutants Wild-type in appearance,...
