Concept explainers
(a)
Interpretation:
The factor units involved in the process of transcription are to be stated.
Concept Introduction:
The term DNA stands for deoxyribonucleic acid. Deoxyribonucleic acid is the most important
(b)
Interpretation:
The factor units involved in the process of translation are to be stated.
Concept Introduction:
The term RNA is stand for the ribonucleic acid. Ribonucleic acid is a type of biomolecule present inside the cell of living organism. The function of RNA is to synthesize protein by the process of translation.

Introduction to General, Organic and Biochemistry
- 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_forwardIn the flow of genetic information, what is meant by the terms transcription and translation?arrow_forward22-49 Based on your knowledge of the chemical properties of amino acid side chains, suggest a substitution for leucine in the primary structure of a protein that would probably not change the character of the protein very much.arrow_forward
- The base composition for one of the strands of a DNA double helix is 19% A, 34% C, 28% G, and 19% T. What is the percent base composition for the other strand of the DNA double helix?arrow_forwardC) NUCLEIC ACID Sketch the general structure of a nucleic acid monomer and name all characteristic chemical groups: TETAAL Sketch the general structure of a nucleic acid polymer and name all characteristic chemical group: Name of bond between monomers: D) LIPID Sketch the general structure of a triglyceride molecule, name the characteristic chemical groups that form the molecule, and label the chemical linkages between the groups: inte imveneg Sketch the general structure of a phospholipid molecule, name the characteristic chemical groups that form the mol- ecule, and show how phospholipids align to create cell membranes. Name the characteristic that distinguishes all lipids from other large molecules:arrow_forwardErwin Chargaff’s discovery that DNA contains equimolar amounts of guanine and cytosine and also equimolar amounts ofadenine and thymine has come to be known as Chargaff’s rule:G = C and A = T(a) Does Chargaff’s rule imply that equal amounts of guanine and adenine are present in DNA? That is, does G = A?(b) Does Chargaff’s rule imply that the sum of the purine residues equals the sum of the pyrimidine residues? That is,does A + G = C + T?(c) Does Chargaff’s rule apply only to double-stranded DNA, or would it also apply to each individual strand if thedouble helical strand were separated into its two complementary strands?arrow_forward
- What are Chargaffs rules and how did they help Watson and Crick figure out the structure of DNAarrow_forwardWhich statement best explains the chemical differencesbetween DNA and RNA? (a) DNA has two different sugarsin its sugar–phosphate backbone, but RNA only has one.(b) Thymine is one of the DNA bases, whereas RNA’s correspondingbase is thymine minus a methyl group. (c) TheRNA sugar–phosphate backbone contains fewer oxygenatoms than DNA’s backbone. (d) DNA forms double helicesbut RNA cannot.arrow_forward4) Paxlovid is treatment for COVID-19 that was recently approved for use because it can drastically reduce the risk for hospitalization and death when taken early in the infection. It is actually a package of two different antiviral drugs. One of those is Nirmatrelvir, which is a modified tripeptide protein mimetic designed to covalently bind to and inhibit the main protease (MPro) from the SARS-CoV-2 virus. This protease recognizes and hydrolyzes peptide bonds at specific points in their sequence, and it is essential for viral replication. a. Below is one of the sequences that Mpro recognizes and cleaves. It cleaves the peptide bond between the glutamine and the glycine. Draw out the structure of a peptide with this sequence, including the appropriate stereochemistry for biological amino acids and assuming the peptide is at physiological pH (pH = 7.4). SGVTFQGKF b. What would the net charge of the peptide be at physiological pH?. c. At what pH would the peptide be net neutral?arrow_forward
