- DNA hybridization process and probe usageAn integrated tool used for conducting automatic and manual sequence alignment of DNA and protein, and inferring phylogenetic relationships between identified sequences. NCBI: GenBank NCBI: Primer Blast Tool NCBI: Nucleotide Blast Tool Molecular Evolutionary Genetics Analysis (MEGA)Gel Electrophoresis Background and Protocol: Gel electrophoresis is a laboratory technique that separates molecules by size using an electric current. The test has a positive and negative side. Do you believe DNA should be loaded on the positive (red) side or the negative (black) side? Please explain why using scientific reasoning. Will larger DNA bands be closer or farther away from the well where you administered samples? Why?
- DNA Profiles as Tools for Identification A PCR-based paternity test is conducted using STRs that consistently produce a unique DNA fragment pattern from a single chromosome. Examining the results of the following Southern blot, which male(s) can be excluded as the father of the child? Which male(s) could be the father of the child?Objective: Get a sense of how genomics, the study of the genome in its entirety,needs to think about how to go about its research. Geonomic DNA is broken up into fragments. The 5’ and 3’ ends of each fragment(a “read”) are sequenced. The sequenced reads are assembled together intocontiguous sequences (“contigs”) based on sequence similarity. The idea is to sequence enough random fragments so that every nucleotide in thegenome is represented on some read. The number of such fragments needed iscalled the coverage, c. The coverage c can be calculated by the formula RL/G, where R is the number ofreads sequenced, L is the average length of a read and G is the total length of thegenome. The units of length are bases (b) or base pairs (bp). Consider a genome whose length is 1000 bp. “Shotgun” sequencing techniquesare applied to the genome, resulting in 20 reads, with an average length of 50 bp.A very important point is that, even though 20 x 50 = 1000, there is no guaranteethat ALL…Objective: Get a sense of how genomics, the study of the genome in its entirety,needs to think about how to go about its research.
