Transcription is the process of which of the following?

Only one strand of DNA is used during transcription of a gene.

If a DNA sequence is upstream of where the gene is, where is these sequence?

Why are genes for rRNA and tRNA considered to be genes even though they do not produce polypeptides?

In one to two sentences each, describe the three processes that commonly modify eukaryotic pre-mRNA.

A 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.

Why doesn't polynucleotide phosphorylase (Ochoa's enzyme) synthesize RNA in vivo?

Refer to Table 13.1. Can you hypothesize why a synthetic RNA composed of a mixture of poly U poly A would not stimulate incorporation of ¹⁴C-phenylalanine into protein?
