A fundamental unanswered question in biology is how a single fertilized mammalian cell can differentiate into a multicellular organism when every differentiated cell type inherits the same DNA. Fundamental to this development process is that different sets of genes are expressed in different cell types. This investigation will show that a key mechanism to regulate gene expression is the way our DNA is covered with specifically modified and altered forms of histone proteins.

生物学中一个基本的未回答的问题是，当每个分化的细胞类型继承相同的DNA时，单个受精的哺乳动物细胞如何分化成多细胞生物体。这个发育过程的基础是不同的基因组在不同的细胞类型中表达。这项研究将表明，调控基因表达的一个关键机制是我们的DNA被特定修饰和改变形式的组蛋白覆盖的方式。
