When explaining genetic coding to a group of students, the instructor discusses gene activation and deactivation. It was stressed that inactivation of a gene requires which of the following processes? Methylation of histone amino acid When an infant is born with gene mutations in his cells, the nurse explains to the parents that accidental errors may be a result of: Select all that apply. Loss of one or more base pairs Substitution of one base pair for another Rearrangement of the base pairs Which of the following statements is true of genetic mutations? Mutations may result from environmental agents. While explaining the individual differences in physical traits in the family group, the health care provider states this is usually a result of: Small DNA sequence variation Which genetic disorders (body system) have a high requirement for oxidative metabolism associated with mitochondrial DNA? Neuromuscular disorders Which of the following statements is true of messenger RNA (mRNA)? mRNA provides the template for protein synthesis. When comparing and contrasting the various forms of RNA, the pathophysiology instructor identifies that ribosomal RNA (rRNA) is unique in that it: Is produced in the nucleolus A physiology instructor asks the students about the purpose of the promoter region on a DNA strand. Which student response is most accurate? Contains amino acids that the RNA polymerase recognized and binds to, thus starting the replication process Splicing of mRNA during processing permits a cell to: Form different proteins A genetic test result r
