In this case, cold air is a smaller cup and warm air is a larger cup. So when the air is colder, the same amount of water vapor will produce a higher relative humidity than the same amount of water vapor in warmer air. This is because we have to consider the amount of water vapor relative to what the air can hold.
The sequence of bases in DNA operates as a true code in that it contains the information necessary to build a protein expressed in a four-letter alphabet of bases which is transcribed to mRNA and then translated to the twenty-amino-acid alphabet necessary to build the protein.
The Genetic Code in DNA. The instructions for the construction of proteins is written in DNA using the genetic code. More specifically, the sequence of bases bonded to the sugar phosphate backbone of the double helix contains information in the form of three-base codons that specify the sequence of amino acids to be used in the construction of proteins.
