Answer:
The synthesis of RNA from a DNA template.
Explanation:
We know that transcription is the first step in gene expression. In the transcription process, information from a gene is used to build a functional product such as a protein. The primary goal of transcription is to produce an RNA copy of a gene's from a DNA sequence.
For a protein-coding gene, the RNA copy, or transcript, carries that information that is needed to build a polypeptide.
Eukaryotic transcripts need to go through some processing steps before starting of translation into proteins.
The answer is D. Because the bird has to be noticed and the brighter the feathers the more likely the chance to be noticed.
The answer is basically D
Answer:
Release of electrons from reducing powers to O2 via four protein complexes allows release of small amount of energy at each step and makes the process energy efficient.
Explanation:
If NADH and FADH2 would reduce O2 directly, a large amount of energy would have been released in a single step. On the other hand, oxidation of these reducing powers through a series of electron carrier release a small amount of energy at each step which in turn is temporarily stored in form of proton motive force across the inner mitochondrial membrane.
Transfer of a pair of the electron to O2 pumps four protons by complex I, four by complex III and two by complex IV. The resultant proton motive force effectively stores the energy of electron transfer. This energy is then used to drive ATP synthesis.
