Exam 18: Recombinant Dna and Biotechnology

Biologists examining the plant gene LEAFY's effect on expression patterns of genes overexpressed and underexpressed LEAFY.They then performed microarray analysis to examine the effects of changes of LEAFY expression on the expression of other genes in the genome.Refer to the table showing the results for four different genes with LEAFY underexpressed and overexpressed, and the control.The expression levels are normalized such that they are 100 for each gene in control conditions. Which gene(s) most likely inhibit LEAFY?

Suppose the first three nucleotides of a restriction site are GCA.If the palindromic restriction site is six nucleotides long, its next three nucleotides will be _______.

An important application of microarray technology, in essence, permits _______ on a larger scale.
