There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C). A base on one of the chains that makes up DNA is chemically bonded to a base on the other chain.
The distance between two adjacent crests of a transverse wave is called the wavelength.
Wavelength is a property of a wave that can be spotted and used as a way of telling waves apart. The parts of the wave that point up are termed crests while any part that is sloping called a trough.
Wavelength is measured in meters. There is no definite spot from which to start on a wave to measure wavelength. The most popular way of measuring wavelength is from crest to the next crest but can also be measured just as accurately from trough to trough.
The scratch test.
The scratch test is used by scientists and people who study rocks and minerals to determine the strength of the rock. They have the scratchers numbered one through ten and scratch the rock or mineral until the scratcher makes a mark in the mineral then they know the strength of the rock.
