transfer solution in and placed them on ice. Next we removed them from the ice and used a sterile loop to pick up a single colony of bacteria. We put a colony in both tubes and then placed both tubes back on the ice. After that‚ we placed a loopful of plasmid DNA into the positive pGLO. We then incubated the tubes on ice for ten minutes. After the ten minutes were up‚ we placed the tubes in a bath of forty two degree centigrade water for fifty seconds‚ and then quickly back onto the ice for two minutes

Antisense refers to opposing the normal order (“sense”) of the code in DNA. The DNA (deoxyribonucleic acid) in genes directs cells to assemble the proteins which comprise living creatures. The order of bases in DNA corresponds to the ordering of amino acids to form the proteins. To produce protein

Genes Review 1) Selective breeding – chosen based on what can be seen and detected (favourable phenotype) Genetic engineering – selected based on genes 2) - DNA are found in nucleus (where most DNA are found)‚ mitochondria‚ chloroplast 3) - Translation requires ribosome‚ mRNA‚ tRNA (anticodon) and amino acids - DNA template‚ polymerase for transcription 4) Mitosis generates daughter cells that are identical Meiosis – homologous recombination 5) DNA coding sequence: 5` GGGCCCTTTAAA

1. The overall goal of this lab was to carry out experiments that clearly demonstrate the different ways DNA genetic information‚ specifically transduction and conjugation. The first half of this experiment focused on exploring the mechanisms of transduction. This was done by creating a spot titer plate for phage carrying kanamycin resistance and E. coli. E. coli was then proven to have gained kanamycin resistance throughout transduction as demonstrated by its ability to grow on a medium containing

with different coloration and colony number. It is also predicted that the agar plate media containing the arabinose will grow a green fluorescent color and the (-)pGlo plate with ampicillin will exhibit no growth at all‚ due to the lack of the plasmid that is resistant to ampicillin. The prediction for the other two plates lacking arabinose is a growth of colorless colonies. Multiple medical experiments are credited towards transformation‚ especially ones involving cancer and the transformation

Isolated DNA Products Amplified Via Polymerase Chain Reaction and Cloned Biotechnology: DNA WPUNJ December‚ 2012 Abstract Isolated DNA from mouse‚ plants‚ and plasmid DNA were used for Polymerase Chain Reaction (PCR) for DNA amplification. The purpose of this experiment was to study the success rate or optimization of PCR of DNA‚ using both manual and kit methods. This set of experiments gives an insight to the relative difficulties associated with the optimization of a variety

Describing chromosomes have been known as structures containing genes that control phenotypic traits that are transmitted through gametes to future offspring. A major piece of evidence supporting this was the Henry-Chase experiment. In 1952‚ Alfred Hershey and Martha Chase published the results of their experiment observations of the process leading to phage reproduction using E. coli cells. Under their electron micrographs it was revealed that the phages exterior structures is formed with a hexagonal
