Explanation Both the arteries as well as veins are made up of three layers or tunics, which are tunica intima, tunica media, and tunica externa, from inside out. The functions of three tunics are described below: Tunica intima: In arteries as well as veins, tunica intima consists of endothelium layer and loose connective tissues. Arteries contain one extra layer in this tunic, which is known as the internal elastic lamina. Its function is to provide a smooth surface, which will reduce the friction of blood and vessel. Tunica media: The larger tunica media in arteries help the artery to expand and accommodate blood during systole and recoil to the normal position during diastole...

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.
