Explanation In the initial 7 weeks of the gestation period, the sex of the embryo cannot be determined. Both would be male and female have similar kind of appearance. The formation of organs starts in the third week. In the third week, the notochord develops. In the fourth week, the embryo has different jaw and head. A long, hollow tube which later on becomes digestive tract is formed. In the sixth week the head becomes larger, the limbs begin to extend

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.
