I believe it starts with the above which is defined as
Triplet of nucleotide bases in transfer RNA that identifies the amino acid
I could be wrong if so sorry,
If a corn plant has a genotype of Ttyy, what are the possible genetic combinations that could be present in a single grain of pollen from this plant.
Geologists call individual layers of sedimentary rocks beds, whereas everal of them together are called strata.
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. The sediment is often formed when weathering and erosion break down a rock into loose material in a source area. Strata are layers of rocks that are laid down as sediment, often in the sea, and are slowly changed by pressure, heat and chemical actions into rocks.
<span>The answer is molecular clocks.
Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages and vice versa.</span>
