Question
Chapter 18.3, Problem 1R
Summary Introduction
To review:
The type of gene library used and its reason for analyzing each of the following:
a. The expression of a gene encoding amylase (a starch hydrolyzing enzyme) in seeds as they germinate.
b. The sequence of the amylase gene in two different genetic strains of corn.
Introduction:
A collection of different cloned deoxyribonucleic acid (DNA) sequences from an organism are called as gene library. The DNA sequences are cloned into a vector for purification, storage, and analysis. There are usually two types of gene library, namely: genomic library and complementary DNA (cDNA) library, which depends on the source of DNA used.

A paper hypothesizes that white flowers are unable to produce anthocyanins (purple pigments) because they lack a functional “A” protein. However, it is also possible that an unknown gene is responsible for the lack of anthocyanins. Now that they have isolated DNA sequences of the “A” allele, design an experiment to use these DNA sequences to distinguish between these two hypotheses.
Select all that would be true if I had a nonsense mutation in an exon of a gene:
The nonsense mutant allele would be the same size as wildtype by PCR-electrophoresis
The nonsense mutant protein would be the same size by Western as the wildtype protein
The nonsense mutant allele would be a different size compared to wildtype by PCR-
electrophoresis
The nonsense mutant protein would be a different size by Western compared to the
wildtype protein
. The position of the gene for the protein actin in the haploid fungus Neurospora is known from the complete genome sequence. If you had a slow-growing mutant thatyou suspected of being an actin mutant and you wantedto verify that it was one, would you (a) clone the mutantby using convenient restriction sites flanking the actingene and then sequence it or (b) amplify the mutantgene by using PCR and then sequence it?

- SIM is toxic to E. coli. Ali has discovered that a novel prokaryote, C.bantaglia genome encodes for a protein, AIN that can degrade SIM. a. In steps, outline how you can construct this genomic library so that recombinant expression can be performed in E. coli? B. After the genomic library has been constructed you are tasked to describe in steps how you would isolate the DNA sequence that encodes for AIN?arrow_forwardWhy are some genes expressed and some not? Please be as detailed as possible.arrow_forwardSTEP BY STEP Exaplanation would be appreciated so I can understand for upcomming exam. In humans, the COL1A1 locus codes for a collagen protein found in bone. A recessive COLA1 allele believed to reduce bone density and increase risk of fractures differs from the wild type allele by the presence a GT in the first intron of the gene. This mutation can be easily screened by PCR, using COL1A1-specific primers followed restriction enzyme digest of the product with MscI. The normal allele is denoted as G and the recessive allele as T. A recent study of 894 women found that 570 were GG, 291 were GT and 33 were TT. (Assume for this exercise that these values reflect both male and female values for the sampled population. What are the frequencies of each allele? What are the frequencies of each genotype? c. Is this locus in Hardy-Weinberg equilibrium? Use the table below to evaluate the significance of any deviation from H-W expectations.arrow_forward
- As a molecular biologist and horticulturist specializing in snapdragons, you have decided that you need tomake a genomic library to characterize the flowercolor genes of snapdragons.a. How many genomic equivalents would you like tohave represented in your library to be 95% confident of having a clone containing each gene inyour library?arrow_forwardThe figure below shows RNA-Seq data (RED) for the D. melanogaster transformer (tra) gene obtained from both adult female and male fruit flies. The blue lines indicate the tra gene structure, with thicker lines indicating exons, and thin lines introns. The 5' end of the gene is on the left, and the 3' end of the gene is on the right. Based on these data, the most likely conclusion is: Males and females express identical isoforms of tra Males express more tra RNA than females The female isoform has fewer amino acids The female isoform has more amino acids The male and female isoforms have different 3'UTRsarrow_forwardTranscriptome analysis involves two separate methodologies: gene expression and RNA seq analyses. The 10 items below are a scrambled listing of the steps used in the two procedures. Identify the steps involved in RNA seq from the list below. Use the numbers in the list to refer to each step. Once the steps for RNA seq have been identified, write the steps in the order in which they are performed during the experiment. (1) DNA sequencing (2) Allow for hybridization and wash excess cRNA. (3) Mix labeled cRNA with array chip. (4) PCR amplification (5) Measure fluorescence intensity to determine abundance of transcripts. (6) Add labeled cRNA at each microarray location.
