Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases? (6A) Question 4 options: They determine the amino acids in the proteins synthesized. They prevent mutations from occurring in the process of DNA replication They help complete the sugar-phosphate backbone of DNA molecules. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.

They determine the amino acids

Explanation: The sequencing of the bases directly code for the amino acids. If anything changes, it would change the code, and could possibly create a different gene all together.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
