Why are transposons considered mutagenic agents? Why is food safety important? Why is Sanger sequencing unreliable in the 15-40 bp range? Discuss why the statement, "Buyer beware" is appropriate, particularly for athletes. What is an STR? Why has it become the method of choice for ...
What are all the blood types? What makes them universal? How are they different from one another? Why might zygospores have spines? Why are transposons considered mutagenic agents? (a) What are the different blood types? (b) What makes them different? Give two types ...
transposonsGene inactivation and deletion are just as important to genome evolution as are duplication and other mutational events. The environment and phenotype (delivered by accessory gene sequences) act selectively in concert to enable E. coli to diversify both ecologically and genetically. Having ...
The gall releases opines that can then be used as an important source of nitrogen and energy for the bacterium (Zupan et al., 2000; White and Winans, 2007). An interesting twist in the tale is that only bacteria that are infected with the plasmid can use the opines, meaning that ...

The big toe plays an important function in balance while walking; the other toes have much less obvious utility. They are clearly evolved from fingerlike appendages for grasping and swinging, like those of arboreal apes and monkeys. This evolution constitutes a respecialization -- the adaptation ...
How important are transposons for plant evolution? Recent advances in genomics and phenomics for a range of plant species, particularly crops, have begun to allow the systematic assessment of these questions... Lisch,Damon - 《Nature Reviews Genetics》...
Where resistance requires the presence of other determinants beyond the actual target of the antibiotic, many auxiliary factors come into play. These resistance determinants are either distributed narrowly within one or a few taxa, or they have become mobilized on genetic elements such as transposons,...
Why are transposons considered mutagenic agents? Explain how a bee sting can cause death to a person. Why are diabetic patients given insulin before surgery? Why did some subjects have a high pain tolerance? Why is it important for newborn babies to have lactose? Why do some p...
How evolution turned a bug into a feature Chuong studies transposons, bits of DNA that infiltrated primate cells as many as 70 million years ago and now make up more than half of the human genome. Some transposons, known as endogenous retroviruses, got there via ancient viruses. When reawaken...
