What kinds of bonds can carbon make

Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules.

Hope this helps.

Explanation:

A carbon can form four covalent bonds. covalent bonds are chemicals bonds that forms between non metals. In a covalent bond, two atoms share a pair of electrons.By forming four covalent bonds, carbon share four pairs of electrons ,thus filling it's outer energy level and achieving stability

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.
