In this article we will discuss about the concept of gene conversion. In eukaryotes reciprocal exchange between loci almost always produces reciprocal recombinants. In Neurospora the linear arrangement of ascospores in the ascus indicates directly which strands have exchanged segments during crossing over. Thus after meiosis in a heterozygote Aa, due to reciprocal exchange the […]

Biology Notes on Overlapping Genes | Genetics
Article Shared by
The below mentioned article provides a note on overlapping genes. It is now becoming apparent that in both prokaryotes and eukaryotes a nucleotide sequence can code for more than one protein. The nucleotide sequence of a gene may be translated into a complete polypeptide chain. Then a part of the same sequence may also code […]
Mapping the rII Locus in T4 | Genetics

In this article we will discuss about the mapping of rII locus in T4. The wild type T4 phage produces small plaques with rough edges on both strains B and K of E. coli. The r mutants (rapid lysis) are easily distinguished by their large, sharp-edged plaques. The wild type phage do not lyse and […]
