Lecture 10: Multiple Testing - UW Genome Sciences

Why Multiple Testing Matters Genomics = Lots of Data = Lots of Hypothesis Tests A typical microarray experiment might result in performing 10000 separate hypothesis tests.

Lecture 4: Random Variables and Distributions

•Before data is collected, we regard observations as random variables (X 1,X 2,…,X n) •This implies that until data is collected, any function (statistic) of the observations (mean, sd, etc.) is also a random variable •Thus, any statistic, because it is a random variable, has a probability distribution - referred to as a sampling ...

Lecture 5: Estimation - University of Washington

Bayesian Estimation: ÒSimpleÓ Example ¥I want to estimate the recombination fraction between locus A and B from 5 heterozygous (AaBb) parents. I examine 30 gametes for each and observe 4, 3, 5, 6, and 7 recombinant gametes in the Þve parents. What is the mle of the recombination fraction? ¥Tedious to show Bayesian analysis. LetÕs simplify ...

STRAWBERRY DNA EXTRACTION - Noble

• Using the procedure above, try extracting DNA from other fruits or vegetables. • Try extracting your own DNA by using the following procedure: ° To an empty collection cup, add 15 drops (2.5 mL) of clear liquid detergent and 5 g (1 tsp.) of salt (NaCl) ° Gently chew the inside of the cheek for 30 seconds.

Banana DNA Extraction - Fleet Science

DNA is found in the cells of every living organism. It is incredibly small, but we can see it by extracting DNA and isolating chains of it. The soap solution contains sodium laurel sulfate, which can break up fats and proteins. During the DNA extraction, the soap pulls apart the fats (lipids) and proteins that make up the membranes surrounding the

Genomic DNA Isolation Methods - cihd.cores.utah.edu

This is a "quick and dirty" (crude lysis) DNA extraction method. DNA extracted in this manner may or may not be suitable for downstream applications or PCR, depending on which locus you are amplifying and the length of the amplicon. Test the compatibility of this method with your experimental design before extracting "precious" samples.

DNA Extraction - CTAB Method

DNA Extraction - CTAB Method We use this method for extracting genome sequencing quality (i.e. unsheared) DNA that can be used for large insert libraries. It was used to extract material for the Micromonas RCC299 complete genome sequencing project, and the Micromonas RCC472 genome sequencing project. This protocol originally came to us from Evelyne

DNA EXTRACTION METHODS - OUSL

•DNA released into solution is extracted with phenol-chloroform to remove proteinaceous material. •DNA is precipitated from the aqueous layer by the additional of ice cold 95% ethanol and salt •Precipitated DNA is washed with 70% ethanol, dried under vacuum and resuspended in TE buffer.
