Simple Experiments in BiologyTHE author of this useful book is education oiEcer of the Central Council for Health Education, and joint editor of Biology. He is therefore very well acquainted with the practical needs of biology teachers, and the guidance they require....
Luria and Delbrück had been working together for months to solve this conundrum, but none of their experiments had been successful. On the night of Jan. 16, 1943, Luria got a hint about how to crack the mystery while watching a colleague hit the jackpot at a slot machine. The next ...
the bacteria to mutate for survival. Others suggested that bacteria routinely mutate randomly, and the development of phage-resistant variants was simplya lucky outcome. Luria and Delbrück had been working together for months to solve this conundrum, but none of their experiments had been successful...
nurse workers inside the brood pile (f,j,n) or foragers near the nest entrance (i,m,q)). By contrast, workers exhibit high diffusivity (relatively high activity probabilities, fast and straight movement) when visiting site with module scores that do not match their own (for example, nurse ...
for quantitative results. Wes' fast time to results also helps them look at all the proteins and post-translational modifications associated with their proteins of interest more efficiently. The day-to-day reproducibility they get with Wes also means they aren't having to repeat experiments when ...
As mentioned already I remember in high school how my biology book stated that living cells were made up of protoplasm, at which time protoplasm was being described in texts as ‘a simple substance that was the basis of life.’ How so simply simple? How such a description now sounds ...
This is our second time working through Apologia Anatomy and Physiology. It is a program that strongly prepared our previous set of children for their high school level biology and other science studies, also through Apologia. Highly recommended–all 20 thumbs (and four paws) way way up. ...
C.Z. performed pilot labeling experiments, with help from D.B., and data analysis, with help from D.B. and X.Z. All authors discussed the results and edited the paper. C.Y. supervised the study. Corresponding authors Correspondence to Chenxu Zhu or Chengqi Yi. Ethics declarations ...
3p) (Supplementary Table 1; see Methods for detailed calculations). Kinetic folding experiments showed that apoMb accumulates an early folding intermediate in which the A, B, G, and H helices are formed among its eight helices (A–H). This then folds to the native state after forming the ...
Consequently, we used ten seeds for all subsequent experiments. Fig. 4 Reduction of seed material and proof of principle with seeds. Reduction of seed material down to one seed (a,b) and application to a set of selected mutants (c-e) with extracted non-hydrolysed, extracted hydrolysed and ...
