question:
'Come and take it' is a historic slogan, first used in 480 BC in the Battle of Thermopylae as 'Molon labe' by Spartan King Leonidas I as a defiant answer and last stand to the surrender demanded by the Persian Army, and later in 1778 at Fort Morris in the Province of Georgia during the American revolution, and in 1835 at the Battle of Gonzales during the Texas Revolution.
answer:
where did come and take it come from


question:
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript.
answer:
what is the role of rna polymerase during transcription


question:
The chloride ion / ˈklɔːraɪd / is the anion (negatively charged ion) Cl. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid / base balance, transmitting nerve impulses and regulating fluid in and out of cells. Less frequently, the word chloride may also form part of the 'common' name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C − Cl bond in which the chlorine is not an anion.
answer:

in which form chloride is present in water
