DNA, or the instructions for making proteins, is found within the nucleus of the cell; while protein synthesis machinery is found in the cytoplasm of the cell. <span>The nucleus is the site of transcription, production of messenger RNA (mRNA) and after being post-transcriptional modified mRNA is exported from the nucleus. Translation of mRNA occurs within the cytoplasm (proteins are synthesized).</span>
Answer:
Enzyme: A biomolecule that speed up the rate of chemical reactions without being used up.
Substrate: A substance or chemical that enter the chemical reaction and is being converted into a new substance (product).
Competitive enzyme inhibition: Inhibition of enzyme's activity by binding of inhibitor to substrate binding site of the enzyme.
Explanation:
Enzymes are the biomolecules that serve to increase the rate of reactions by lowering down the required activation energy. The enzyme is never used up during reactions.
Substrates are the chemicals that undergo a chemical change and produce products.
For example, Glucose is the substrate for hexokinase enzyme and is converted into glucose 6 phosphate (the product).
When the inhibitor competes with the substrate for the binding site on the enzyme and does not allow the substrate to bind to the enzyme, the process is called competitive enzyme inhibition. It can be overcome by increasing the concentration of substrate in the system.
guanine binds with cytosine (C)
uracil binds with adenine (A)
cytosine binds with guanine (G)
so the anticodon in CAG
Isotonic because water is going both in and out of the cel
