Milk production in lactating women requires about per day. milk production in lactating women requires about per day. 100 to 300 kcal 200 to 400 kcal 400 to 600 kcal 700 to 800 kcal

For milk production alone,  it is suggested that breastfeeding women, in general, must consume about 400 to 600  calories per day. It is because a nursing mother's body changes months after delivering. Her baby's breastfeeding patterns also change as the baby grows so the mother needs an extra amount of calories.   

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.
