Concept explainers
(a)
To determine: The charge category of lysine.
Introduction: Lysine can be defined as an amino acid that is essential for the biosynthesis process of proteins. Lysine also has many other applications in the field of medicine.
(b)
To determine: The property of lysine that enables it to interact with the DNA.
Introduction: The DNA or the deoxyribonucleic acid is composed of
(c)
To determine: The effect of acetylation on lysine interaction with the DNA and gene expression activation.
Introduction: The process of acetylation is a

- If an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides? Will the globin most likely be fully functional, partly functional, or nonfunctional? Why?arrow_forwardSuppose that a DNA segment has the following nucleotide sequence: CTC ATA CGA TTC AAG TTA. Which of the following nucleotide sequences would be found in a complementary mRNA strand? (a) GAG UAU GAU AAC UUG AAU. (b) GAG TAT GCT AAG TTC AAT. (c) GAG UAU GCU AAG UUC AAU. (d) GUG UAU GGA UUG AAC GGU.arrow_forwardWhich group is nonpolar and affects gene expression? Which functional group(s) shown above is (are) present in all amino acids? Which functional group shown above can act as a base?arrow_forward
- What processes are involved in attaching ubiquitin to a target protein?arrow_forwardOnce translated into proteins: (a) How many nucleotides are there? (b) How many codons are there? (c) How many amino acids?arrow_forwardWhen glycoproteins are synthesized in the cell, at what stage of the polymerization of the protein are the sugar groups added: Prior to translation, cotranslationally, or posttranslationally?arrow_forward
- The base sequence on one strand of DNA is ATGTCTATA(i) Give the base sequence of its complementary strand.(ii) If an RNA strand is transcribed from this strand what would be the base sequence of RNA?(iii) What holds these base pairs together?arrow_forwardWithin a cell, the amount of protein made using a given mRNAmolecule depends partly on(A) the degree of DNA methylation.(B) the rate at which the mRNA is degraded.(C) the number of introns present in the mRNA.(D) the types of ribosomes present in the cytoplasmarrow_forwardWhich are the Characteristics of Regulation of Binding Site?arrow_forward
- 16) PROTEIN SYNTHESIS: A) Describe the process of protein synthesis. Be sure to use transcription and translation in your answer (and explain the parts involved in each process) B) Why is RNA transcription a necessary process?arrow_forwardHow does the information stored in DNA direct the synthesis of proteins?arrow_forwardwhich statement about genetic code is not true? A) mRNA is read 3 bases at a time, which are called codons. B) There is one initiator codon that codes for an amino acid. C) Each amino acid is coded for by only one codon. D) There are 3 termination codons that do not code for amino acids. E) Each codon is specific for only one amino acid. An anion has an equilibrium potential of -40 mV. What direction are the chemical and electrical forces acting on the anion at the resting membrane potential (-70 mV)? A) Both the chemical and electrical forces are directed out of the cell. B) The chemical force is directed out of the cell and the electrical force is directed into the cell. C) The chemical force is directed into the cell and the electrical force is directed out of the cell. D) There is insufficient information to answer this question. E) Both the chemical and electrical forces are directed into the cell.arrow_forward
