Answer:
The correct answer is- Nirenberg and Heinrich, 1961.
Explanation:
Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.
Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.

Answer: CO alarms have a life expectancy of around seven years. The CO alarm will beep every 30 seconds or display ERR or END. If a CO alarm is at its end-of-life, replacing the battery will not stop the beep. Most detectors will beep 4 or 5 times in a row about every 4 seconds. Do not mistake dangerous levels of poisonous gas for a detector with low battery.
