the r group or side chain of the amino acid glutamic acid is hydrophilic. The R group of the amino acid valine is hydrophobic. w
boyakko [2]

Answer:

You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.

This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.

Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

During DNA replication, _____. a. four identical DNA molecules are produced each parental b. strand serves as a template for the
BaLLatris [955]

Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand

Explanation:

In semi-conservative DNA replication,

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand

- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.

Thus, option B perfectly describes semi-conservative replication of dna
