If science is to be defined at,
science is a systematized body of knowledge. Science is where the organized set
of facts were obtained and is used as a tool, model or paradigm to gather such
evidential data. Science is not a fact but an existential body in which comprises
the study of the anatomy and physiology of a certain object by the means of
observation, hypothesis, experimentation, interpretation and conclusion of the
gathered facts. Or what others would describe the scientific process.
Answer:
It's DNA.
Explanation:
<em>DNA</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>most</em><em> </em><em>recent</em><em> </em><em>utility</em><em> </em><em>to</em><em> </em><em>determine</em><em> </em><em>the</em><em> </em><em>origin</em><em> </em><em>of</em><em> </em><em>an</em><em> </em><em>organism</em><em> </em><em>and</em><em> </em><em>it's</em><em> </em><em>powers</em><em> </em><em>compared</em><em> </em><em>to</em><em> </em><em>it't</em><em> </em><em>weaknesses</em><em>.</em>
<em>Nowadays</em><em>,</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>primary</em><em> </em><em>tool</em><em>:</em>
<em>Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids. </em>
The right answer is the promoter.
• The promoter is a nucleotide sequence that allows the transcription of the gene into mRNA. It is recognized by the RNA polymerase that initiates transcription. During the synthesis of the RNA, the promoter indicates which gene must be expressed and therefore which proteins the cell must produce. In an operon it is common to all genes.
• The operator is a segment of DNA and / or messenger RNA to which a chemical signal (a regulatory molecule) binds. It can be either a repressor signal or a transcription activating signal (DNA operator) or translation (RNA operator) of the genes of the operon. The RNA polymerase does not recognize this structure.
