Final answer:
PCR have any spots for writing vital signs is 1) 1
Step-by-step explanation:
PCR, or Polymerase Chain Reaction, is a laboratory technique used to amplify and replicate a specific segment of DNA. It is commonly used in various applications such as genetic research, medical diagnostics, and forensic analysis.
Vital signs, on the other hand, refer to the objective and measurable signs of disease, including body temperature, heart rate, breathing rate, and blood pressure. These vital signs are typically recorded using specialized equipment, such as a thermometer, stethoscope, and sphygmomanometer. Therefore, the correct answer is option 1) 1, as PCR does not have any spots for writing vital signs.
