Each cell expresses, or turns on, only a fraction of its genes. The rest of the genes are repressed, or turned off.
The turned on genes are then first transcribed into messenger RNA by the process of Transcription.
Then the mRNA is Translated into protein by the process called Translation.
This is how the specific genes are expressed.
<span>Glycolysis is a process that can be seen as occurring in eukaryotic cells. This process is active when cellular energy levels are low; and the regulatory enzyme is inhibited by ATP. This process releases energy that is labeled as 'free'. After this process the released energy goes to form ATP molecules, which are high in energy.</span>
Answer AND Explanation:
Darwin describes natural selection as a process whereby nature selects those organisms that have favourable characteristics to be parents of the next generation. The individuals possessing the favourable traits are better suited to the prevailing environmental conditions. This enables them to stand a better chance to survive in the struggle for existence due to limited resources.
