Answer:
A genetic sequence, the TATA box, is a transcriptions start site and initiates transcription through the formation of RNA polymerase. Negative regulation may inhibit the initiation of transcription and/or repress gene expression.
Explanation:
proteins called transcription factors bind to the TATA box, this triggers RNA polymerase to start synthesizing RNA to DNA
The correct answer is: D) H2O… CO2
Redox reactions are reactions of reduction (molecules tend to gain electrons) and oxidation (molecules tend to lose electrons).
Photosynthesis is a set of redox reactions. In photosynthesis electrons are removed from water (H2O) to carbon dioxide CO2 and then used to turn CO2 into organic compounds.
The first step: Oxygen in water is oxidized (light energy required)
The second step: Carbon in CO2 is reduced; sugar is formed (dark reaction).
Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case
Answer:
The Lineweaver- Burk plot is representation of Lineweaver-Burk equation of enzyme kinetics in graphical plot that is presented by the Hans Lineweaver and Dean Burk.
In the presence of a non competitive inhibitor shows higher y-intercept than a control in absence of any inhibitor whereas the x intercept is the same as the control that suggests or tells that maximum enzyme activity of the reaction is decreased, Higher Y intercept than controls means that it is same as 1/Vmax. The X intercept indicates that there is no effect on Km of the enzyme reaction.
