Suppose You Invented a Way to Genetically Transform All of the Cells

question 70

Multiple Choice

Suppose you invented a way to genetically transform all of the cells expressing meristematic identity in a plant so that they would fluoresce green. Suppose too that this transformation was heritable by daughter cells, such that they would also fluoresce as long as they continued to express meristematic identity, but would lose the ability to fluoresce irreversibly upon differentiating to a nonmeristematic cell type. You then genetically transform all the cells of a tree, and soon after examine a cross section of a branch stem. A few years later, you examine a cross section of another branch stem. What should you expect to see in comparing the two stem cross sections?

• A)a continuous green ring in the first sample, but multiple discontinuous rings in the later sample
• B)a discontinuous green ring surrounding a continuous green ring in the first sample, but multiple continuous green rings in the later sample
• C)multiple discontinuous green rings in the first sample, but multiple continuous green rings surrounding a discontinuous green ring in the later sample
• D)a continuous green ring surrounded by multiple discontinuous green rings in the first sample, but a single continuous green ring in the later sample
