Using the drop down menus identify the structures common to all cells

The correct identification would be:

Label A- DNA

Label B- cell membrane or plasma membrane

Label C- Ribosome

Label D- Cytoplasm

The above mentioned four structures that are common to all the cells present in an environment.

DNA genetic material is present in all the cells. It is present in nucleus in eukaryotic cells and in nucleoid region in prokaryotic cells.

Plasma membrane is a semi-permeable membrane present around all the living cells.

Similarly, cytoplasm refers to jelly like substance present in all the cells. It supports cell organelles.

Ribosomes form the site for protein synthesis in all the living cells.

The correct identification would be:

Label A- DNA

Label B- cell membrane or plasma membrane

Label C- Ribosome

Label D- Cytoplasm

Explanation:

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.
