Both normal and transient flora can become opportunistic pathogens. True or False
ElenaW [278]

Answer:

True

Explanation:

Normal flora are  microorganisms that are regarded as resident organisms, which can be found on or in an individual and do not cause any disease.

the transient flora refers to microorganisms that are found on the skin or the hands which are there through direct contact with person or object, and are easily removed by routine hand hygiene. Example is Norovirus that can cause stomach flu.

Opportunistic pathogens are microorganisms such as the bacteria and virus, which can only cause infection when the immune system is down. This means that , these organisms can not cause any infection as long as the immune system is ok.

In this case, the normal and transient flora like Norovirus can only cause infection when the immune system is down. That is why they are regarded as opportunistic pathogens.

When the gene encoding a certain cytoskeleton protein is deleted, the resulting mutant cells round up and do not form their norm
Sophie [7]

Answer: N-terminal green fluorescent protein (GFP)

Explanation:

Protein synthesis takes place in ribosomes located in the cell cytoplasm, in which amino acids are transported by transfer RNA corresponding to each amino acid to the messenger RNA where they bind in the appropriate position to form new proteins. <u>The messenger RNA has a sequence of nucleotides that are translated into protein, as each codon (set of three amino acids) codes for one amino acid</u>.

Genes are the storage units of genetic information, so they are segments of DNA that contain the information on how the cells of the organism should function. Each gene codes for a protein, so if a gene is damaged or absent, the protein will not be obtained. In this case, mutant cells with a deleted gene, will round up and wont form their normal appendages. This mutation can be rescued or repaired with a gene that encodes an N-terminal green fluorescent protein (GFP) fusion of the protein. The N-terminal end is the amino-terminal end and it refers to the end of a protein that ends with an amino acid that has a free amino group. The C-terminus or carboxyl-terminus is the end of a protein that ends in a carboxyl group. The convention for writing peptides is to place the C-terminal end to the right and write the sequence from the N- to the C-terminal end. So, when an N-terminal green fluorescent protein (GFP) fusion of the protein is expressed, the gene will produce the protein with a GFP tag.

<u>GFP is Green Fluorescent Protein</u>, and it is a protein produced by the jellyfish <em>Aequorea victoria</em> t<u>hat emits bioluminescence in the green region of the visible spectrum</u>. When a gene is fused to another gene (at either the N- or C-terminus, although in this case it is the N-terminus), the entire messenger RNA is translated together as if it were a single fused protein. <u>Thereby, since the protein will be produce with a GFP tag, it can be seen under the microscope and it will be apropiate to use in studying cellular localization and activity.</u>

There are some considerations that this problem does not question, such as that there must be a start codon for protein synthesis and a stop codon, and this stop codon must not be in the middle of the gene or between the gene and the GFP tag.
