Answer:
Chemically altered nucleosides derived from canonical ribo-or deoxyribonucleoside-derivatives of adenosine, cytosine, guanosine, and uridine or thymidine are found in all types of nucleic acids, DNA and RNA. They are particularly abundant in noncoding RNAs, such as transfer RNAs and ribosomal RNA of higher organisms. By increasing the structural diversity of nucleic acids, modified nucleosides play important roles in gene expression and in regulating many aspects of RNA functions. They also contribute to nucleic acid stability and to protection of genetic materials against virus aggression. In this chapter we present a historical overview of the discovery, occurrence, and diversity of the many naturally occurring modified nucleosides that are present in both DNA and RNA of diverse organisms. We also briefly describe the different enzymes that accomplish these nucleic acid ‘decorations’. More information about the structure, function, biosynthesis and evolutionary aspects of selected modified nucleosides in DNA and RNA and their corresponding modification enzymes can be found elsewhere in this volume.

Answer:4. "I should avoid the use of salt substitutes containing potassium."
Explanation:
Salt substitute potassium are salt substitutes which contains "potassium chloride" alone or mixed with regular salt which is "sodium chloride", these are available as a way to cut back sodium intake which contributes to high blood pressure. However in this patient, taking salt substitute potassium could pose a health risk because lisinopril raises blood potassium levels, therefore concurrent use of lisinopril and salt substitute potassium would further increase the blood levels of potassium (hyperkalemia) which could cause side effects like irregular heart rhythm and in severe cases lead to kidney failure, muscle paralysis, cardiac arrest.
Answer:
Andy remains protected from PTSD even after multiple traumas in life because of avoiding events, places and objects that trigger the memory of trauma. He also took psychotherapy including cognitive behavior therapy and eye movement desensitization and reprocessing (EMDR). He took healthy diet and exercise regularly to develop mental and physical strength.
Explanation:
PTSD is post traumatic stress disorder which occurs due to traumatic events and symptoms arise after re-experiencing the event, flashbacks of event, bad dreams and frightening thoughts. Avoiding the places, objects and people who gives a flashback of the trauma, taking psychotherapy to handle flashbacks and triggers well, EMDR therapy to desensitize retina and change the way how you react are some approaches used by Andy to protect himself from PTSD. He also focused on good health i.e. healthy dietary intake, good sleep schedule, and regular exercise.
