Cooing and babbling are early stages of speech development. As babies get older (often around 9 months), they begin to string sounds together, incorporate the different tones of speech, and say words like mama and dada (without really understanding what those words mean).
The map distance between two genes, measured in centimorgans or map units, equals the percentage recombination frequency between the two genes--the likelihood of offspring with copies of those genes on the same chromosome that come from different parents.ave. dna image by Allyson Ricketts from Fotolia.com. The concept of map distance in a genotype refers to where genes are located on a chromosome but does not refer to physical distance; rather, map distance refers to the tendency for a crossover to occur between genes.
Q : What is the new distance between the remaining gene You perform DNA microarray experiments on cancer cells at different time points (0, 6, and 12 hours) following the addition of a novel anti-cancer drug. You obtain the following normalized and scaled microarray data for the genes Myc, p53, and Ras.
