Interpretation:
The correct reason should be determined for the given statement; does a single base-pair substitution in a strand of DNA always result in a new amino acids in the protein coded for by that gene.
Concept Introduction:
A base is nitrogen containing heterocyclic compound which is found in DNA and RNA.
Gene is the biological unit of heredity which holds the information to build and maintain their cells and pass genetic traits to offspring. In cells, a gene is a portion of DNA.
Amino acids are the molecules which containing an

- Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long-chain fatty acids. Many of the symptoms are similar, and include hypoketotic hypoglycemia, low ketone levels and low blood sugar with fasting, and damage to the liver, heart, or muscles due to fatty acid buildup in those tissues. Symptom severity varies with the form of the deficiency. The following abbreviations are used: carnitine acyltransferase (carnitine palmitoyltransferase), CPT and carnitine/acylcarnitine translocase, CACT. Identify each symptom or effect as a deficiency of CPT I, CPT II, or CACT. CPT I deficiency CPT II deficiency CACT deficiency Answer Bank acyl carnitine not transported into mitochondrial matrix acyl carnitine not converted to carnitine in matrix long-chain fatty acids not transferred to carnitinearrow_forwardDiabetes is a group of metabolic diseases characterized by abnormal regulation of blood glucose levels. If left untreated, diabetes leads to chronic hyperglycemia and numerous pathological complications.
