why do different cells in your body look and act differently despite having the same dna?

Explanation:

Gene expression is the biological process where the genetic information stored in DNA is converted into functional products, primarily proteins, through transcription and translation. The other options are incorrect: genes do not express emotions, they do not move between cells in this context, and physical appearance related to genes refers to phenotype, not gene expression.
For the second question, while the options are not fully visible, the core reason is differential gene expression: different cells activate or silence specific sets of genes from the same DNA, leading to distinct structures and functions.

Answer:

1. How your cells use DNA instructions to make proteins
2. (Full answer requires visible options, but the underlying principle is differential gene expression: different cells turn specific genes on or off, leading to unique structures and functions despite identical DNA.)
