Which two amino acids are shown on the left side of Figure 3? Use Figure 2 to answer this. To which chemical groups do these amino acids belong? Were you able to identify their chemical characteristics based on your rules? If not, you should go back and revise your rules!
DNA and RNA
Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, deoxyribonucleic acid, is one of the natural components. Deoxyribonucleic acid is a double-stranded molecule. Watson and Crick postulated the double-stranded model of the helix. A deoxyribonucleic acid is a molecular group that carries and transmits genetic information from parents to offspring. All eukaryotic and prokaryotic cells are involved.
DNA as the Genetic Material
DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it as a genetic component. Certain organisms have different types of nucleic acids as their genetic material - DNA or RNA.
Genetics
The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents several diseases in a human being. Thus, genetics also creates an understanding of various medical conditions.
DNA Replication
The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.
![**Exercise B: Peptide Bond Formation**
Figure 3 shows two individual amino acids, and then those same two amino acids after they have been linked together by a **peptide bond** to form a **dipeptide**. Addition of more amino acids linked by peptide bonds would form a **polypeptide**, the precursor to a functional protein.
[Diagram of two amino acids combining into a dipeptide through a peptide bond. The structures show amino groups, carboxyl groups, and R groups, highlighting the bond formation.]

**Answer the below questions in your own document.**
- Which two amino acids are shown on the left side of Figure 3? Use Figure 2 to answer this.
- To which chemical groups do these amino acids belong?

On the dipeptide shown in Figure 3, label the **peptide bond** that was formed when the two individual amino acids were joined. Label the free **amino and carboxyl groups** at the ends of this dipeptide (not in the R groups). These are often referred to as the **N-terminus** (amino-terminus) and the **C-terminus** (carboxyl-terminus) of a peptide or polypeptide. (Note: “peptide” refers to a chain of a small number of amino acids, whereas “polypeptide” refers to a longer chain, potentially that corresponding to an entire protein.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3eeb3e5a-eda3-4be2-a8da-0aed76f38e3a%2Fdbc5352a-3a3a-4a17-af6d-251b342d2669%2Fjfcbpdm_processed.png&w=3840&q=75)
