To draw: The three possible dichotomously branching phylogenetic trees showing evolutionary relationships between the three domains: Bacteria, Archaea, and Eukarya. Introduction: The phylogenetic tree can be constructed from DNA sequences or morphological study. The organism that shares a very similar morphology, or DNA sequences are most likely to be the descendant from a common ancestor. The closely-related organisms that are immediately descended from a common ancestor is called the sister group.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
