All you have to do is keep track of what letter matches which letter in each column. For example
(DNA strand B) A= (DNA strand A) T
You have the matching letters for each. Do you understand? If not I can help clarify. :3
Answer:
Plants and animals assimilate carbon-14 from carbon dioxide throughout their life. When they die, they stop exchanging carbon with the biosphere and their carbon-14 content begins to decrease at a rate determined by the law of radioactive decay.
Radiocarbon dating is basically a method designed to measure residual radioactivity.
Explanation:
Carbon-14 is a weakly radioactive carbon isotope; It is also known as radiocarbon, and is an isotopic stopwatch.
Radiocarbon dating is only applicable to organic materials and some inorganic materials (not applicable to metals).
Proportional gas counting, liquid scintillation counting, and accelerator mass spectrometry are the three main methods of radiocarbon dating.
The radiocarbon, or carbon-14, is an isotope of the carbon element that is unstable and weakly radioactive. The stable isotopes are carbon-12 and carbon-13.
Carbon 14 is continuously formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen-14 atoms, rapidly oxidizing in the air to form carbon dioxide and entering the global carbon cycle.
Accelerator mass spectrometry (AMS) is a modern method of radiocarbon dating that is considered the most efficient way to measure the radiocarbon content of a sample. In this method, the content of carbon-14 is measured directly in relation to carbon-12 and carbon-13 present. The method does not take into account beta particles, but the number of carbon atoms present in the sample and the proportion of the isotopes.
Answer:
Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.
Explanation:
Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations. They are caused by the altering the the single base units in the DNA of the species.
In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.
The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.
