A. True or false. Support your answer
a. RNA differs from DNA in that is single-stranded and cannot base pair.
b. The fetal β-globins arose from a gene duplication that occurred 200 million years ago, which gave rise to a different forms of b-gobins expressed in the fetus and in the adult.
c. A total genomic library will be larger than a cDNA library for a given cell.
d. Histone acetyltransferases affect transcription by both altering chromatin structure to allow accessibility to the DNA and by adding acetyl groups to histones that can bind proteins that promote transcription.
e. The proteins in neurons and white blood cells are completely different.
f. Maternally âcoded transcription factors determine segmentation in Drosophila melanogaster larvae.
