Answer:
Ozarks, that is a proper noun, as it is capitalised for being the name of something rather than just an object
Explanation:
Remark
I see what you mean. It doesn't look like anything has happened in the quoted passage that would suggest he was dead. He is certainly disorientated. You have two choices.
Choice One
"I had not seen him approach, and the sudden appearance made me start." This happens to people all the time when they are concentrating and don't hear or see the things going on around them. But in this particular case, he was only putting a key in a door. That doesn't take much concentration, particularly if you have done this 1000 times before. If you allow me to speculate just a little bit, it sounds like an old fashioned boarding house. It would be hard to sneak up on someone.
Choice Two
Once inside the room, he runs straight to the back room and checks the door, but does not know if it is locked. Then comes back and asks for a favor. It's really odd. It's a hint.

Out of the 64 codons found in our biological system, the first was experimentally deciphered by Marshall Nirenberg and Heinrich Matthaei.
<h3>What is genetic code discovery of codons?</h3>
- The key to unlocking the genetic code was discovered when they conducted an experiment using a strand of synthetic RNA with numerous uracil units to tell a chain of amino acids to add phenylalanine.
- In 1961, Francis Crick, Sydney Brenner, Leslie Barnett, and Richard Watts-Tobin made the initial discovery that a single amino acid can be encoded by three nucleotides in DNA [7]. Scientists made the discovery of the life's code in that instant.
- Friedrich Miescher isolated "nuclein," which is DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a special molecule.
- The twenty amino acids that make up protein are arranged according to a code that is formed by the four bases of DNA, which at first glance appear to be randomly arranged. Watson and Crick were the first to realize this.
