Question
Chapter 22, Problem 146AE
Interpretation Introduction
Interpretation: The number of turns present in the
Concept introduction: The alpha helix consists of a coiled polypeptide chain. The secondary structure of DNA is similar to the secondary structure of proteins which is an alpha helix structure held together by hydrogen bonds. The alpha helix in DNA consists of two right-handed polynucleotide chains that are coiled together by number of turns about the same axis resulting in alpha helical structure.
To determine: The number of turns present in the

- Although 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? A virus is a particle that contains DNA or RNA that is surrounded by a coat of protein that can replicate only in a host cell. The influencza virus shown in this electron microscope image is an RNA virus.arrow_forwardDescribe 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.
