Answer:
The biological level of organization represented by all of the three steps of gene expression products is <em>the central dogma of molecular biology.</em>
Explanation:
DNA is divided up into functional units called genes. Each of them provides instructions for a functional product, that is, a molecule nedeed to perform a job in the cell. In many cases, the functional product of a gene is a protein.
The functional products of most known genes are polypeptides. Genes that specify polypeptides are called protein-coding genes.
Not all genes specify polypeptides. Instead, some provide instructions to build functional RNA molecules, such as transfer RNAs and ribosomal RNAs that play roles in translation.
The construction of polypeptide involves two major steps: transcription and translation. During the transcription, the DNA sequence of gene is copied to make an RNA molecule and in translation the sequence of mRNA is decoded to specify the amino acid sequence of the polypeptide.
<h2>
Answer</h2>
Nucleus: Protons and Neutrons
Electron Cloud: Electrons
<h2>
Explanation</h2>
An atom consists of three subatomic particles i.e Electrons, Protons and neutrons. Protons and neutrons are found inside of the nucleus of an atom whereas electrons are found in the orbits that surround the nucleus of an atom known as electron cloud. In the atom Protons contain positive charge to attract the electrons which contain negative charge and the neutrons contain no electrical charge.

The fuel used in nuclear reactors is commonly uranium. Its unstable nature means that when it is hit with an electron it splits into two new atoms, one of which is Krypton. In the process of splitting large amounts of energy is released. This energy is used to heat water to produce steam, the steams rising energy is used to turn a turbine which produces the electric output of nuclear power stations.
