Is a single colony from a ligation with many fragments a clone of cells?
Is a single colony from a ligation with many fragments a clone of cells?
Homework Answers
A single colony is not a single cell. Rather it is clone of cells of the desired make up. A single colony obtained from ligation of many fragments IS a clone of cells.

3. A bacterial colony represents all the progeny of a single cell. We refer to a colony as a clone, because bacteria reproduce asexually so all of the daughter cells should be genetically identical. However, some bacteria that were sensitive to the antibiotic at the beginning of the experiment were resistant by the end. What naturally occurring event led to resistance? (Hint: We are working with pure cultures of laboratory strains, so there are no superbugs around sharing their genes...

you have heard about three different vectors to clone DNA fragments (plasmids, BACs, and YACs). Which of these would be most appropriate to clone a DNA fragment with the length of 5,000 bp, and which would be most appropriate for a fragment of 200,000 bp? The genome of fruit flies has a size of about 175 Mbp. Assuming that each base pair has a height of 3 Angstrom (1 Angstrom is 10^-10 m), how long is the genome of a...

Please help. Thanks. From your libraries of clones, how do you use colony hybridization to find the “correct” clone? Discuss the steps you would use. You are attempting to clone novel kinase genes using the DNA from the protein kinase B [PKB] gene’s kinase domain as your probe.

The human genome contains about 3x10^9 bp of DNA. How many 200-kb fragments would you have to clone into a BAC library to have a 90% probability of in- cluding a particular sequence?

A colony derived from flask # 2 (with compound B) is used to examine the histidine gene. By PCR, a double stranded piece of DNA is made. The PCR product is cleaved with either EcoRI alone, BamHI alone, or with both restriction enzymes simultaneously. Following electrophoresis of the three DNA samples, the following fragment sizes are found: EcoRI: fragments of lengths 3 kb, 5 kb and 14 kb. BamHI: fragments of lengths 7 kb and 15 kb. EcoRI + BamHI:...
