DNA: How many spacing base pairs between two double-crossover units so that the two double-crossover units are parallel to each other?

Hello! I have no idea what my professor is asking here, any help is greatly appreciated. Thank you so much!

Is RNA directly used in DNA replication?

1.RNA is not involved during the process of genome replication

2.RNA is needed to provide the 3' -OH groups at the start of construction of new DNA

3.tRNA is matched to the codons on the genome during DNA replication

4.All of the monomers used to construct the new DNA molecule are first constructed as RNA and then a -CH3 group is added

What chemical you use to induce cell competent for transformation? What are three important features a vector should have?  Why it is important to have the recovery process during transformation? What is the next step after recovery process?

Bar eye (B) is a dominant and sex-linked trait of Drosophila. Curved wings (cu) and black body (bl) are recessive traits, both found on chromosome 2, separated by 24 map units. A homozygous Bar-eyed, black-bodied female is crossed to a true-breeding male expressing curved wings. The heterozygous F1 female is then crossed to a male expressing all three traits. At what frequency among the F2 would you expect to find a completely wild type male?

How often would you find a Bar eyed, curved wing female?
