Unformatted text preview: that encodes a functional pigment • c is an allele that does not encode functional pigment EACH HAS INDIV GENOTYPE Maize variegation • Ds elements can transpose using the Ac transposase. • Ds elements can insert into C alleles disrupting gene function (Ct) • Kernels with the Ctc genotype are yellow Figure 11.27 REVERTIBLE: CAN BE UNMUTATED BY TRANSPOSON MOVING BACK OUT. Activator (Ac) and Dissociation (Ds) elements control maize variegation • If the Ds element is excised, the C allele is restored. • This happens in some, but not all, cells during development Figure 11.27 Activator (Ac) and Dissociation (Ds) elements control maize variegation • Creates a purple spot or streak in an otherwise yellow kernel. IN KERNAL • Variegation is evidence of TE movement Figure 11.27 Sleeping Beauty Question 3 • Sleeping beauty was isolated from an inactive DNA transposon in fish. What might have made it inactive? • ANSWER: It had accumulated mutations, similar to Ds. Sleeping Beauty Q...
