lab 4

Based on your analysis of Cross A and B, what is the most likely mode of inheritance of the glass trait?

autosomal recessive

Based on your analysis of Cross C and D, what is the most likely mode of inheritance of the yellow trait?

x-link ed recessive

Which of the following statements is correct regarding agarose gel electrophoresis?

A small DNA fragment will travel faster than a large fragment in a direction based on the fragment's negative charge.

At STR locus 15, the mother is homozygous (7,7) and the father is heterozygous (7,4).

Assuming Mendelian inheritance, what is the chance that their child will be homozygous for 7 repeats (i.e. 7,7) at STR locus 15?

50%

In this lab, you will be simulating the role of a biomedical engineer. You are interested in testing out the function of variants of the  AraP  regulatory regions in the expression of a therapeutic gene.

To test each variant, you have placed green fluorescent protein (GFP) under the control of these regulatory regions, therefore GFP will be a  reporter  gene. Expression of the GFP should only be observed if  arabinose  is added to the growth medium.
