The lagging strand of DNA is built in which direction?

The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h ) body. Assume that a cross is made between a fly with normal wings (homozygous) and a hairy body and a fly with vestigial wings and normal body hair (homozygous). The wild-type F1 flies were crossed among each other to produce 1024 offspring. What is the genotype of the F1 flies?

When an amoeba stretches out a pseudopod to move, which element of the cytoskeleton is making that happen?

All of the following are ways RNA differs from DNA except: 

Potassium ions (K+) are attracted to Chloride ions (Cl-). What type of bond are they forming?
