Question

a conjugation experiment set up between F+ HIS+ LEU+ THR+ PRO+ bacteria and F- HIS- LEU- THR- PRO- bacteria and allowed to continue for 25 minutes. at this time the mating is stopped and the genotypes of the recipient F- bacteria are determined. the no of colonies for the genotype HIS+ IS 0 , LEU+ IS 12, THR+ IS 27 and PRO+ IS 6. what is the first gene to enter and order of the genes?

Answer 1

"This chapter discusses the genetic analysis in micro-organisms.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.

In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.
