Summary Introduction

(a)

To identify: The genes expressed in a specific type of brain cell.

Introduction:

A particular gene can be identified through its expression in a particular cell and its interaction with other genes. To study the gene expression, specific mRNAs corresponding to a gene of interest are to be identified and reverse transcribed to form cDNA. This sequence can be identified through RT-PCR, DNA microarray analysis, and RNA sequencing. To study a particular protein, multiple copies of the gene fragment encoding that protein are synthesized through polymerase chain reaction (PCR). These gene fragments are then inserted into the expression vector to synthesize a large quantity of proteins encoded by the gene in a process known as gene cloning.

(b)

Summary Introduction

To isolate: The neurotransmitter gene expressed in brain cells.

H gene assorts independently from the I gene. Both on autosomes. One man and one woman, both of HhIAIB genotype. Determine the blood type of progeny and fractions out of 16
Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
