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.
DNA sequencing is technology that allows researchers to determine the order of bases in a DNA sequence. The technology can be used to determine the order of bases in genes, chromosomes, or an entire genome. In 2000, researchers completed the first full sequence of the human genome.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
