Question

Ten new rapid lysis mutants of bacteriophage t4 were obtained following a mutagenesis experiment and numbered 1-10. they were isolated on the basis of their plaque morphology when grown on e. coll b and their inability to grow on e, coll k12. these mutant phages were then analysed using the eight known rapid lysis deletion mutants shown below: in this map the rectangles represent the segment of dna that has been removed by each deletion?

Answer 1

Ten new rapid lysis mutants of bacteriophage T4 were obtained and analyzed using known rapid lysis deletion mutants to identify genes and DNA sequences involved in rapid lysis.

Step-by-step explanation:

When studying bacteriophage T4, ten new rapid lysis mutants were obtained and numbered 1-10. These mutants were isolated based on their plaque morphology when grown on E. coli B and their inability to grow on E. coli K12. These mutant phages were then analyzed using eight known rapid lysis deletion mutants.

Deletion mutants are segments of DNA that have been removed from the genome. In this case, the rectangles on the map represent the segments of DNA that have been deleted. By analyzing the mutant phages using these deletion mutants, researchers can determine which specific regions of DNA are responsible for rapid lysis.

In conclusion, the study of these mutant phages and their deletion mutants helps to identify the genes and DNA sequences involved in rapid lysis, providing valuable insights into the biology of bacteriophage T4.
