Each question is true or false... can you please explain why each question is either true or false, depending on the answer. Thank you.
1. Consider an atom of nitrogen (N), which is more electronegative than an atom of hydrogen (H). N has 5 valence electrons, whereas H only has 1 (H can only form 1 total pair of electrons in it's valence shell) ... Given this information: If an atom of N were to bind with 3 H atoms, the newly formed compound NH3 would likely be a polar molecule.
2. Given this information: If an atom of N were to bind with 3 H atoms, it the newly formed compound NH3 would likely be hydrophobic.
3. DNA that contains 40% G will be more stable in changing conditions (such as increasing heat) than DNA containing 40% A.
4. DNA polymerase is binding to DNA.
5. The nitrogenous bases on the nucleotides used by DNA polymerase to synthesize new strands of DNA have been removed.
6. There are no free-floating deoxyribonucleotides in these cells.
