Hi, i'm doing my masters in microbiology. I need to present a novel idea for a research proposal for a presentation. This does not necessarily have to be about micro. I went through a couple of papers on cell biology and immunology to come up with future prospects of research but really am having a ...

plz help....i need this urgently......i have isolated a mutant cell of yeast that cannot take part in a particular step of galactose metabolism...in order to identify the gene responsible for it.....i have transformed the cell with plasmid vectors containing fragments of genomes of wild type yeasts....

ok yeah....dat is a gud way...thnx....

i need to know an experimental proof by which we can determine that DNA synthesis occurs during S phase of the cell cycle.....please help...

A cross is made between two E.coli strains....Hfr-arg+bio+leu+.....and F-arg-bio-leu-.....interrupted mating studies revealed that arg enters the recipient last. so arg+ recombinants are selcted on a medium containing only bio n leu. these recombinants are tested for the presence of bio+ and leu+. t...

is it possible to use PCR in DNA sequencing?? explain......i knw PCR can amplify a particular sequence of DNA....But m not so sure about hw it helps in sequencing....:/

isotype, idiotype, allotype- can someone differentiate between them in a little detail??? the text book isnt helping much.....

the answer contains a lot of marks, so i thought it requires something extra. and by the way, a lot of things are available in books. but still people post their questions out here.

so i guess the answer would be saturated and long chain fatty acids....because their increase would stabilize the cell membrane...

How are amino acids synthesized and broken down to TCA cycle intermediates?(i know the synthesis and breakdown of glycine ,phenylalanine and lysine....but i dont know how to represent this answer...please help.)

bacteria growing at 20 degree celsius is shifted to 30 degree celsius. state there will be more:-
a) saturated or unsaturated fatty acids,
b)long or short chain fatty acids.
explain with reason.....(i need it asap)

thank you so much for your help.
