Answer:
EtBr inserts between the stacked bases in the DNA double helix.
Explanation:
- EtBr is used for visualizing DNA bands as it fluoresces under the UV illumination.
- EtBr is an aromatic compound that is capable of inserting itself between the stacked bases of the DNA double helix.
- The hydrophobic environment around the base pairs where the EtBr intercalates is responsible for the fluorescence. As the EtBr molecule intercalates between these base pairs the cation of EtBr sheds the water molecules associated with it and this causes it to fluoresce under UV light as water is a quencher of fluorescence.
The Hazard Communication Standard fits this definition best. This standard is created by OSHA to reduce the amount of workplace incidents that involve the handling of hazardous materials.
Answer: During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
Explanation:
Bb is black fur because the dominant (always shown as the capital in this case B) is always shown when present. the red fur is a recessive trait (always shown as the lower case in this case b) and is only shown when there’s no dominant allele present
