Answer asap! must be correct for points given! super important! answer with the letter format, (example: answer = and provide an explanation why it is that answer.
in a certain plant species, the allele for wrinkled seeds (w) is dominant to the allele for smooth seeds. what is the phenotype result of a cross between a true-breeding wrinkle-seeded group of plants and a true-breeding smooth-seeded group of plants?
a.
1/4 smooth seeds, 3/4 wrinkled seeds
b.
1/4 wrinkled seeds, 3/4 smooth seeds
c.
all wrinkled seeds, no smooth seeds
d.
all smooth seeds, no wrinkled seeds

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
