Chapter 4, Problem 1SA
Summary Introduction
To review:
The key features of a cell.
Introduction:
Cells are the smallest unit of life.
Expert Solution & Answer

Explanation of Solution
Cells are what make up all forms of life in the world. They are the smallest unit of life that can exist independently and carry out all the biochemical processes that sustain life.
A cell is made up of genetic material consisting of Deoxyribonucleic Acid or DNA, and a jelly like substance called cytoplasm consisting of water, salts, and other chemicals. These are enclosed inside a cell membrane.
Cells arise only from preexisting cells.
Conclusion
The key features of a cell are
- They are the smallest unit of life that can live independently.
- All forms of life are made of one or more cells.
- Cells arise only from preexisting cells.

Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
