6. Consider Model 1, a. In which direction is the DNA molecule read? b. The DNA strand and pre-mRNA strand are anti-parallel. With this in mind label the 5' ends of the pre-mRNA strand in Model 1. c. In which direction is the pre-mRNA molecule constructed?

a. The DNA molecule is read in the 3' to 5' direction during transcription.<br /><br />b. In the anti-parallel structure of DNA and RNA, the 5' end of the pre-mRNA strand would be on the right side of the DNA strand.<br /><br />c. The pre-mRNA molecule is constructed in the 5' to 3' direction.
