Chapter 1, Problem 3EQ
Summary Introduction
To review:
The micrograph of chromosomes using a cell from a person with Down syndrome.
Introduction:
The micrograph is a karyogram from a normal cell with 46 chromosomes where pairs of homologous chromosomes are arranged in descending order of size and position of centromere for the same chromosome size. Chromosomal abnormalities related to polyploidy and aneuploidy can be identified using karyogram.

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. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas.
