The dominant allele D causes dextral (right-handed) shell coiling while the recessive allele d leads to sinistral (left-handed) coiling. The gene product is transferred from nurse cells into the egg as shown in the diagram for a homozygous (dd) mother.

WebAnnealing and Extension Because most polymerases are highly active in the temperature range typical for primer annealing (55–70°C), the annealing and extension steps of a PCR protocol can often be consolidated into a single step. Using a two-step PCR protocol rather than the standard three-step protocol can WebDenaturation: The reaction temperature is increased to 95 °C for 10 sec to melt all dsDNA. Annealing: The temperature is lowered to 60 °C for 30 sec to promote primer and probe (if included) binding to the template. Extension: Subsequent elongation occurs at an increased temperature of 72 °C, which is optimal for TaqDNA polymerase ...
