Answer:
In order to make E. coli bacterial cells glow green, we need to insert a gene that can be translated into the <u>green fluorescent protein.</u> This gene is well-known as <u>gfp</u> and can be inserted either in the DNA or plasmid of the bacteria. The genome insertion procedure would follow the conventional method where the DNA will be first cut using restriction enzymes and then would be ligated. This approach has been extensively applied to test the fate of bacteria in the environmental systems.
A schematic diagram on insertion of gfp in the plasmid of bacteria is shown in the figure. The left side diagram shows that gfp is inserted and right side figure shows glowing bacteria in the presence of UV.
In a given homologous chromosome pair, two recombinant chromatids are generated by a single crossover event.
Homologous chromosomes are the chromosomes that possess the same genes at the same loci and also have the same structure. One chromosome of the homologous pair is paternal while the other is maternal. Crossing over even takes lace between homologous chromosomes only.
Crossing over is the event that involves the interchange of genetic material between homologous chromosomes. Due to this event, the offspring receives genes from both the parents. The exchange of genetic material occurs between two non-sister chromatids in crossover, hence two recombinants are obtained.
