Most cancers arise from cells that have accumulated multiple mutations.

You have a piece of DNA that includes the following sequence: 5′-ATAGGCATTCGATCCGGATAGCAT-3′ 3′-TATCCGTAAGCTAGGCCTATCGTA-5′ Which of the following RNA molecules could be transcribed from this piece of DNA?

In mammals, females have two X chromosomes and males have a single X chromosome in addition to a Y chromosome. Thus, females have a ‘double dose’ of all the genes on the X chromosome. Females address this imbalance by inactivating one of the two X chromosomes in every cell. How do the cells do this?
