• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...

The LEP gene codes for an anorexigenic hormone. Interestingly, breastfeeding has been shown to alter methylation of the promoter of this gene, leading to increased LEP expression. What is likely happening in response to breastfeeding? - Breastfeeding decreases the methylation of the promoter of the LEP gene, increasing the spacing between nucleosomes. A patient with xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because of a mutation in...

When explaining cancer that extends to organs or tissues distant from the site of origin, what term should the nurse use? A) Apoptosis b) Benign C) Metastasis D) Malignancy correct answers Metastasis What would the nurse expect to occur when a patient's cancer is caused by mutations of a proto-oncogene? A) Apoptosis B) Increased cell division C) Production of monoclonal antibodies D) Decreased cell responsiveness to growth factors correct answers Increased cell division A patient...

Describe the differences between deletion, insertion, substitution, and nonsense mutations. Provide an example of each using the following piece of DNA: TAC CAG ATA CAC TCC CCT GCT ACT. Indicate if any of the mutations are frameshift, nonsense, or missense mutations. correct answersMutations occur when a base sequence of DNA is permanently changed (Tortora, Funke, & Case, 2016). Mutations can either be harmful to an organism or beneficial depending how it alters a cell and its activity. A delet...
