use it's an embedded double crossover. This is why they're going to be doing preparatory work over the next four weeks, so when the 15-day shutdown begins they'll have demo'd all the asphalt and concrete from around the rails."
The PCR products were purified in 5 mM Tris-HCl (pH 8.5) and transformed into SK-1 to estimate the homologous recombination efficiency via double crossover (Figure 1).
"For example, State departments of transportation [DOTs] that plan to implement new interchange designs, such as the diverging diamond interchange [also known as the double crossover diamond] and the restricted crossover U-turn, can create virtual interchanges using the lab's modeling software to conduct detailed analyses of these designs and others like them.
The interval between the yellow and white loci is designated as "I"; the interval between white and crossveinless is designated as "II." Gametes produced by trihybrid females in both crosses fall into four general categories: those resulting from no crossovers between the loci under study (NCO); those resulting from a single crossover in interval I (SCO I); those resulting from a single crossover in interval II (SCO II); or those resulting from a double crossover event (DCO).
The correct answer is the double crossover diamond (DCD) interchange, also called the diverging diamond.
First division restitution could retain 50% of the heterozygosity over all chromosomal regions with a single or double crossover. If double crossovers occurred, SDR would only keep 50% of the heterozygosity between the two breakpoints.

The display combines breathtaking high speed double crossovers from four corners of the arena when closing speeds may reach 90mph, with shows of the individual and combined skill which include amazing feats of balance, machine control, team work and courage."
