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

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
