messenger RNA (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus to the cytoplasm where it attaches to a ribosome.
transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.
<span>The specific heat of the metal is 0.5 cal/ (0C.g). This means the energy needed is 0.5 cal to raise the heat of 1 gram of metal by 1 degree C. Therefore, the energy needed to raise 100 g of the metal by 20 degrees C is:
0.5 * 20 * 100 = 1000 cal.

Explanation:
This statement is correct because the concept of integrating body and mind in physical activity was responsible for the expansion of physical activity, in addition to activities that promote only the well-being of the body aesthetically, but as a set of activities responsible for improvement of health, intelligence, emotional, creativity, as well as an instrument of social integration. The practice of physical activity releases endorphins in the brain, which is a natural substance produced by the brain that is associated with well-being, mood and joy, and this effect occurs during and after physical activity.
Answer:
d. Autoradiographies
Explanation:
Based on the information provided within the question it can be said that the technique that is mainly used for this are Autoradiographies. This is a technique that is mostly used for X- ray film to visualize molecules or fragments of molecules that have been radioactively but are also used for analyzing the length and number of DNA fragments using a special method called gel electrophoresis which is then used to compare the various DNA samples.
