Question
Chapter 24.5, Problem 2Q
Interpretation Introduction
Interpretation:
The forces holds together the double stranded DNA molecule are non-covalent bonds has to be determined.
Concept introduction: Targeted sequence of double stranded DNA is heated at tempreature
Hydrogen bonds are non-covalent bond which are weaker than covalent bond. Non-covalent bonds are necessary to form double helical structure of DNA.

How do amino acids bond together ? Use a basic diagram of an amino acid molecule ato show how 2 amino acids would bond together. Identify the ty of reaction as well the type of bond formed.
The "melting point" of a DNA molecule is the temperature at which the double-helical strand breaks apart. Suppose you are given two DNA samples. One sample, sample A, contains 45% G-C base pairs, while the other sample, sample B, contains 64% G-C base pairs. The total number of bases is the same in each sample. Which of the two samples, sample A or sample B, has a higher melting point?
A. sample A
B. sample B
C. The melting point is the same for both.

- Describe the structural differences between DNA and RNA. The monomers in nucleic acids are called nucleotides. What are the three parts of a nucleotide? The compounds adenine, guanine, cytosine, and thymine are called the nucleic acid bases. What structural features in these compounds make them bases? DNA exhibits a double-helical structure. Explain. Describe how the complementary base pairing between the two individual strands of DNA forms the overall double-helical structure. How is complementary base pairing involved in the replication of the DNA molecule during cell division? Describe how protein synthesis occurs. What is a codon, and what is a gene? The deletion of a single base from a DNA molecule can constitute a fatal mutation, whereas substitution of one base for another is often not as serious a mutation. Explain.arrow_forwardAlthough RNA is single-stranded, the strand sometimes folds back on itself to give a complementary portion. What would be the complementary portion of the RNA fragment having the bases uracil-cytosine-guanine?
