Biology Lab quiz 4 Latest Updated A+ Guide Solution

Where would the DNA be located within a eukaryotic cell? nucleus is defined as the use of living organisms to perform a task that benefits humans and other living organisms. Biotechnology Homogenization is the process that breaks down large fat globules into smaller fat globules. False in the DNA isolation process, detergent was used to emulsify cellular and nuclear membranes. in the DNA isolation process, the filtrate and reagents are kept in an ice bath because cold temperatures are required to stabilize the DNA. Ethanol cannot be added to the test tube too quickly because it will break up the DNA precipitate. true In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na+) neutralizes the negative charge of DNA. true Rank the following steps in the correct order that you would use to isolate DNA from strawberries 1.)transfer strawberry filtrate to test tube 2.)dissolve meat tenderizer and add it to test tube 3.)add ice cold ethanol to test tube 4.)wait for DNA precipitate to form 5.)spool DNA precipitate onto glass rod in order to prevent the DNA from breaking, the glass rod should be spun In one direction Detergent is used in the DNA isolation process because it facilitates homogenization. Gel electrophoresis can be used to separate molecules by (Select all that apply) length, size , weight, number of atoms in gel electrophoresis, how are the DNA samples added to the wells? A micropipet is used.
