In a wild-type neurospora , protein e (encoded by the haplosufficient gene "e") normally homodimerizes, and the e-e dimer catalyzes a biochemical reaction necessary for the production of a dark pigment. ed represents a mutant, dominant-negative allele of gene e. what is the predicted phenotype of a fungus cell of genotype e+/ed, and why? (a) wild type (normal production of the dark pigment), as ed is a negative allele (b) wild type (normal production of the dark pigment), as eis haplosufficient (c) mutanmutant (no pigment production), as the mutant allele ed is dominantt (no pigment production), as no e-e dimers will form in the heterozygote (d) mutant (no pigment production), as e is haplosufficient
the speaker and transformer are the devices that consume the electrical energy and release the sound as an output in this process the phenomena which are acquired is electromagnetic induction. the sound energy can also be converted into the electrical energy but fir this process high temperature and high frequency is required. the sound energy is important as it informs us about the character, place and time.
hope this !
gel electrophoresis is a molecular biology technique, used in the separation of proteins and nucleic acid molecules. when gel electrophoresis is performed, a negative control is used along with a positive control to detect presence of any possible contamination.
in negative control lane, no band is expected as it is considered as blank. thus, 'a band in the lane of negative control shows presence of some sort of contaminating molecules in the sample dna.'
