The correct option is D.
Transcription is the process by which the information in a DNA molecule is copied into an mRNA strand. Replication is the process by which two new strands of DNA are formed from a single parent DNA. Both the DNA and the RNA are composed of four different bases, three of the bases are the same while one is different for the DNA and RNA. It is only the RNA that has uracil while it is only the DNA that has thymine. Thus, Uracil is involved during the process of transcription since it is an mRNA strand that is formed while thymine is the one involved during the process of replication since it is a DNA molecule that is formed.<span />

The circulatory system carries wastes from all parts of the body to the urinary system, which expels the wastes.
Carbon, Nitrogen, Sulfur, Hydrogen, and Oxygen.
Answer:
Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
Keratoacanthoma: a clinically distinct variant of well differentiated squamous cell carcinoma.
What is squamous cell carcinoma?
Squamous cell carcinoma (SCC) of the skin is the second most prevalent type of skin cancer, distinguished by aberrant, rapid squamous cell proliferation. Most SCCs are treatable if detected early.
Skin squamous cell carcinoma is also known as cutaneous squamous cell carcinoma (cSCC). Adding the word "cutaneous" distinguishes it as a skin cancer from squamous cell malignancies that can form inside the body, such as the mouth, throat, or lungs.
