I would hire this person because the disease is non-communicable. Plus, small cold and cough problems will not affect the performance of the person and therefore, there are little chances that he/she will take frequent holidays. Further, morally this job will help the person financially, in getting the proper treatment of the disease, if it occurs. And this will also raise the confidence and personality of the person. If the person has the skills that match our requirements, I will definitely hire him, despite his chances of developing multiple sclerosis.
Answer:
Yes, P. Falciparum and T. Cruzi undergo similar antigenic variation because of repetitive genomes evolved by time.
Explanation:
Living (i.e., actively proliferating) repeats are dynamic elements which reshape their host genomes by generating rearrangements, creating and destroying genes, shuffling existing genes, and modulating patterns of expression. Dead repeats (i.e., those which are no longer able to proliferate) constitute a palaeontological record, which can be mined for clues about evolutionary events and impetus. The dynamic nature of repeats leads to a rapid evolutionary divergence that can be used in species identification and phylogenetic inference. Repeats can also provide passive markers for studying processes of mutation and selection.
The genomes of these protozoan parasites, like all eukaryotic genomes, have been colonized by diverse repetitive elements. Repetitive sequences can be artificially divided into two groups: interspersed repeats and tandemly repeated DNA. P. falciparum undergoes antigenic variation ans similar anitgenic variation is present in t. cruzi because of repetitive sequences resembling each other.
You are a eukaryote. Your cells are eukaryotic. Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects.
Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Prokaryotes include two groups: bacteria and another group called archaea.
