Vit c experiment essay

Before introducing the individual vector systems,we discuss some general properties of viral transduction vectors. Transgenes may be incorporated into viral vectors either by addition to the whole genome or by replacing one or more viral genes.

These are artificial vesicles that can act as delivery agents for exogenous materials including transgenes. Delivery Efficiency — For most applications, transfecting or transducing as many cells as possible is preferred, especially when it is necessary to detect the presence of rare transgene products.

These are the powerful tools for research and have possible applications in gene therapy. Heat, in an aluminium water bath filled with boiling water, with stirring, until the agar solution boils, then allow to cool. Wash of any spills with water 2 Take 5cm3 of 0. This was the most commonly reported benefit.

When conducting the experiment, 50ml of 0. Such DNA may recombine with that of its new host, introducing new gene variants. Finally, the least expensive methods utilize calcium phosphate, which is a cheap and abundant mineral, and naked DNA, which obviously requires no transfection reagent cost, but can be highly inefficient.

In the majority of applications however, a high percentage of cell death is simply not acceptable. Due to the efficiency with which viruses can deliver their nucleic acid into cells and the high levels of replication and gene expression it is possible to achieve, viruses have been used as vectors not only for gene expression in cultured cells but also for gene transfer to living animals.

For example, a reagent that efficiently delivers plasmids may not efficiently deliver DNA oligonucleotides. Disadvantages include inhibition of cell growth and induction of heterogeneous morphological changes in cells. M ; displays no effect on Cav3.

Vitamin C lab report

At the entry site, endonucleases cut the DNA into fragments of 7, nucleotides, and the double-stranded DNA separates into single strands.

Anecdotal evidence from early explorers and particularly from British naval doctors similarly attested to the need for fresh food to prevent scurvy but it was the pioneering experiments of James Linda Scottish naval surgeon, in that gave a scientific basis to these observations.

Safety There are no hazards associated with the basic investigations described here DCPIP is irritant but at the concentration used here is a low hazard and does not need a warning label. Viral methods, while highly efficient, can be quite time consuming, typically taking anywhere from two weeks to one month to complete.

Because it is derived from glucose, many animals are able to produce it, but humans require it as part of their nutrition.The limitation of the experiment is about the freshness of the fruit may different, it would affect the concentration of vitamin C in the fruit.

The internal but the challenge is going to be designing a meaningful experiment and collecting enough results to complete the analysis well.

DCPIP will be useful as an indicator of the concentration of vit C but a calibration curve might be useful.

Effect of size on uptake by diffusion

In the original Milgram study at Yale University, subjects were recruited for an experiment ostensibly investigating learning. The naïve subjects were the “teachers” and a confederate was the. The question is whether the vitamin C keeps the same quantity under certain conditions.

6 My research question is focusing on the effect of heat on vitamin C.

This experiment has also some sentimental meaning to me, especially since I was born in Poland the cultural affiliation is strongly inculcated. The limitation of the experiment is about the freshness of the fruit may different, it would affect the concentration of vitamin C in the fruit.
