Scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries. This bioengineered tissue is grown from living cells. The cellular process that enables the cells to grow and develop into tissue is - 

• conjugation
• meiosis
• budding
• mitosis

Which of these must occur during S phase of the cell cycle so that two daughter cells can be produced during M phase?

• The DNA must be replicated.
• The chromosomes must be joined.
• The cytoplasm must be separated.
• The cell membrane must be expanded.

The sequence of nitrogenous bases in DNA varies widely. The sequence of the bases in DNA is most important for which of the following?

• Providing instructions for the traits of an organism
• Preventing mutations from occurring during DNA replication
• Allowing the DNA to have the shape necessary for replication
• Helping form the sugar-phosphate backbone of DNA molecules
