MRNa's are composed of codons. Codons are a sequence of three nucleotides that come together to be transcribed by an anti-codon to form units for genetic coding. For example, AUG is a codon and upon transcribing becomes the protein Methionine. In this case, they differ in the terminal codon. UAG is a stop codon while UAC is Tyrosine. The first sequence is complete,while the other one is not.
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
Photosynthesis. Figure 2.3: Photosynthesis: In the process of photosynthesis, plants convert radiant energy from the sun into chemical energy in the form of glucose - or sugar. Water (6H2O) + carbon dioxide (6 CO2) + sunlight (radiant energy) = glucose (C6H12O6) + Oxygen (6O2).
Root system represents the underground part of the plant. It includes roots, tubers, and rhizoids.
Explanation:
Shoot system refers to the components of a plant, which grows above the ground. It includes stems, leaves, flowers, seeds, fruit, and buds.
