• 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...

ACAAI Online Joint Board Certification Review Exam Questions with Correct Answers Which of the following statements is true. A.) Signaling through the TCR is sufficient to activate naïve T cells B.) CD28 is a costimulatory molecule that is needed to activate naïve T cells C.) CD80 and CD86 interact with CD4 to inhibit TCR signaling D.) Costimulatory molecules activate phosphatases that inhibit Zap70 - Answer-B.) CD28 is a costimulatory molecule that is needed to activate naïve T cells...

B-B AAMC FL 1 Exam Questions and Answers Based on the data presented in the passage, which statement best describes the HSP110ΔE9 allele? -Answer-According to Figure 1, as compared to HSP110WT, HSP110ΔE9 slows tumor growth, and thus, it is cancer-suppressing. According to the data in Table 2, HSP110ΔE9 counteracts the ability of HSP110WT to prevent protein aggregation and prevent apoptosis; thus, the HSP110ΔE9 allele is dominant to the HSP110WT allele. Based on the passage, in MSI CRC ...
