PROTEIN SYNTHESIS I: TRANSCRIPTION<br />
<strong>An</strong>drea Bierema<br />
Learning Objectives<br />
Students will be able <strong>to</strong>:<br />
• Explain the processes necessary for transcription <strong>to</strong> begin.<br />
• Explain how DNA is transcribed <strong>to</strong> create an mRNA sequence.<br />
• Describe the role of polymerase in transcription.<br />
• Recognize that protein synthesis regulation (i.e., changes in gene expression) allow cells <strong>to</strong><br />
respond <strong>to</strong> changes in the environment.<br />
• Explain which gene-expression regula<strong>to</strong>ry fac<strong>to</strong>rs are at play for transcription.<br />
Overview<br />
This chapter focuses on how transcription works; that is, how information coded in the DNA molecule is read<br />
<strong>to</strong> create an mRNA sequence. Please see the previous chapter for a general overview of transcription <strong>and</strong> DNA<br />
<strong>and</strong> RNA bases before continuing <strong>to</strong> read this chapter.
