Question
Chapter 26, Problem 12EQ
Summary Introduction
To review:
The reason for an egg-laying defect in n536, n355 and n540 strains of Caenorhabditiselegans(C.elegans) in the experiment done by Horvitz and Sulston.
Introduction:
C.elegans is a transparent nematode, a commonly used model organism in research. It has been used in developmental biology to study the developmental stages of an embryo because of its transparency.

8. Transcription and Translation Practice: (Video 10-1 and 10-2)
A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense
DNA strand and label the 5' and 3' ends.
B. Use the antisense strand that you create in part A as a template to create the mRNA
transcript of the gene and label the 5' and 3' ends.
C. Translate the mRNA you produced in part B into the polypeptide sequence making sure
to follow all the rules of translation.

- Molecular Biology Question You are working to characterize a novel protein in mice.
