Which location is not appropriate for hand washing after working with human material in the laboratory

1 answer:

7 0

A hand washing sink in the break room is not an appropriate location for washing hands after working with human material in the laboratory.

A vital part of laboratory safety is hand washing. In fact, this 20-second method is regarded as one of the most crucial steps utilized to stop chemicals, radioactive materials, and microbiological agents from infecting you and the area around you.

Even though gloves should be used when handling hazardous items, adequate hand washing should still be done on a regular basis. If you don't wash your hands right away after taking off your gloves, germs could spread to your mucous membranes and infect you, or they could contaminate neighboring surfaces and endanger other lab workers.

Every laboratory that uses chemical or biological agents must have access to at least one sink for hand washing, ideally close to the room exit. To prevent contamination, the sink must be cleaned frequently, and soap must be available for hand washing.

Leni [432]

Answer:

Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.

You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.

If the code reads. CGC GCG CGC GCG etc.

The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.

anygoal [31]

Answer:

The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.

Explanation:

The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.
