Multiple ChoiceIf a DNA sequence is upstream of where the gene is, where is these sequence?626views4rank
Textbook QuestionBased on discussion in this chapter, Why are genes for rRNA and tRNA considered to be genes even though they do not produce polypeptides?198views
Textbook QuestionIn one to two sentences each, describe the three processes that commonly modify eukaryotic pre-mRNA.192views
Textbook QuestionA number of experiments have demonstrated that areas of the genome that are transcriptionally inactive are also resistant to DNase I digestion. However, transcriptionally active areas are DNase I sensitive. Describe how DNase I resistance or sensitivity might indicate transcriptional activity.243views
