Answer:
2) DNA Makes Up Our Body Structure Like Muscle
Explanation:
There Are Pairs In Our DNA That Determine Certain Physical Features Or Traits. ( These Are Called Gene's ) The Genes That You Have In Your Body Right Now, Makes Up Your Genotype. This Genotype Then Determines Your Physical Appearance, Which Is Called Your Phenotype!
Ans.
Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.
Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.

Explanation:
The cell must be lysed (broken open) to release the nucleus. the nucleus (if present) must also be open to release the DNA. at that point the DNA must be protected from enzymes that will degrade it, causing shearing. [[ once the DNA is released, it must then be precipitated in alcohol...]
