In this lesson you will introduce to proteins and nucleic acids. You will learn about the various levels of organization of proteins as well as about the structures of nucleic acids, DNA and RNA
By the end of this lesson, students should be able to:
- describe the monomers in both proteins (amino acids) and nucleic acid (nucleotides)
- use appropriate terminology related to the levels of organizational structure of proteins: primary, secondary, tertiary and quaternary structures.
- list the various intermolecular forces involved in each type of structure with specific examples.
- list the twenty amino acids from which proteins are synthesized from. You should be able to recognize the functional groups in amino acids,
- classify amino acids into polar, nonpolar and charged amino acids. Know their names and overall structures.
- describe the formation of peptide bonds in proteins and phosphodiester linkages in nucleic acids.
- compare and contrast DNA and RNA, nucleotide and nucleoside.
- Explain why the two strands in DNA run in opposite directions.
- Recognize and list the two kinds of nitrogenous bases: pyrimidines and purines
- Describe the formation of a double helix in DNA.
Let’s start by examining protein first in the video lesson below. Please take notes as you watch the video. Also write down the review key points at the end of the lesson in your notebook.
Below is a table of all twenty (20) amino acids for you to study. You must be able to classify the amino acids into the three groups: nonpolar, polar and charged based on their R group.
As formative assessment, please answer all questions in the worksheet below. The answer key is included.
Below is a video lesson on Nucleic Acids. As usual, please watch the video lesson carefully, pause it to take notes down.
In order to fully understand the structures of nucleic acid, please print the note below. Read through the explanation on the differences between DNA and RNA and highlight key features.
