QUESTION 1 What is genetic modification (GM) of crops and how is it done? GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA. The characteristics of all living organisms are determined by their genetic makeup and its interaction with the environm...

· Turbidity Measurements - Spectrophotometer sends light through a culture. Light absorbance can give a rough measure of cell density in the tube ·Agrobacterium - Crown-Gall Disease - The crown gall is where the stem of the plant connects with the roots of the plant. Causes tumours, parasitism. THIS IS BAD, we don't want this one. Agrobacterium is the only one that can use opine as a carbon and nitrogen source. It robs the plant of organic carbon. We can use agrobacterium to introduce ne...

A common cloning strategy for introducing foreign genes into plants with Agrobacterium employs all the following features except: A) a selectable antibiotic marker such as kanamycin resistance. B) a shuttle vector with 25 bp T-DNA repeats flanking the foreign gene of choice. C) a Ti plasmid lacking its T-DNA segment. D) active vir gene products from the altered Ti plasmid. E) an ability to induce crown gall formation in infected leaves. - Answer-B) a shuttle vector with 25 bp TDNA repeats ...

_____________________ interprets the information in mRNA into the protein sequence - ️️Transfer RNA (tRNA) A gel matrix made of agarose or polyacrylamide does what? - ️️Slows the movement of the molecules - Larger molecules move more slowly through the gel than smaller molecules A. thaliana can be genetically manipulated using the bacterium - ️️Agrobacterium tumefaciens, which can inject DNA into the plant cells After multiple rounds of PCR, the vast majority of molecules have th...

BIOL 1610 Quizzes (pre & post class assignments with quiz 1-4 & exam 1-2) Classes 1 and 2: Post Class Assignment - Read the scenario: You get in your car to drive to class. You turn the key, and the engine starts making a clicking sound, but does not start (1). You think to yourself, "The battery must be dead" (2). So, you borrow the battery from your neighbor's car (with permission, of course) and exchange it for the one in your car (3). You figure that if the battery in your car is ...

1. Three (3) eggs are boiled and all weigh 2g. The eggs are placed in a 15% solution ofNaCI and reweighed after 30 minutes. Tell me which egg was isotonic to the NaClsolution, which egg was hypotonic to the NaCI solution, and which egg was hypertonic tothe NaCl solution and explain how you know this. - Egg 1 = 2.5 grams hypertonic, Egg 2 = 2 grams isotonic, Egg 3 = 1.8 grams hypotonic. 5 properties of life - cellular organization, metabolism, homeostasis, growth and reproduction, heredity ...
