Summary Introduction

To analyze:

The choice of the female of certain insect species among the two males categorized as first and second male for the mating.

Introduction:

The process of internal fertilization is common in vast majority of terrestrial organisms and in some of the aquatic animals. The process of fertilization is the union of egg and sperm to form the zygote, which is followed by the embryo development.

The term sperm competition takes an immense important in insect species. Sperm competition is a process in which the sperms of different males compete to fertilize with the eggs of the same female. In 1970Geoff Parker published his experiments involved a series of matings of one female with two males. His findings indicates that the number of offspring were more in case of fertilization with the second male.

Overview of Transformation Protocol   -Prepare competent bacteria for transformation: Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes. Incubate both tubes in a 37 C water bath for 5 minutes.   Questions: 1)What is the selectable marker in this experiment? How…
Based on your results, which suspect's DNA best matches the DNA found at the crime scene?
In oxidase test with Pseudomonas aeruginosa, the cell cultures on the slide turn colorless to be purple after tetra-methyl-p-phenylenediamine dihydrochloride (TMPD) is added. In the reaction, OTMPD is electron acceptor O cytochrome c is the electron source oxygen is terminal electron acceptor OH2 produced is electron donor
