what are the advantages of molecular biology, and what impact would they make in modernising a lab?
372608
The various techniques encompassed by the term molecular biology have been revolutionary in the modern laboratory. Experiments that would normally take weeks or months can now be done in hours or days. Experiments that couldn't be done are now feasable.\n\nAs for your lab specifically, it would depend on what projects your lab is engaged in.

Hi.  I am a scientist who works in the pharmaceutical/biotech industry.  In my field, we do a wide variety of things:\n\nIn terms of cell-based drug discovery assays, we can take cells from a person, grow them in petri dishes and test new drugs that we've developed on them to see if the cells live or die in response to the drug. (Of course, this is in very VERY general terms; it's much more complicated than that).  If we want to test a variety of cell types against a variety of chemical compounds, we can use automated technology called High Throughput Screening... In HTS, very sophotisticated robots carry out 96 or 384 experiments at a time.   \n\nMolecular biologists can change cells by adding viruses or DNA plasmids and allowing the virus or plasmid to assimilate itself into the host cells's normal DNA.  This process is called transfection.  This is useful if you want to overexpress a gene or condition that you want to study or model/test a drug against.  Molecular biologists can also clone these plasmids and grow more of them for large-scale experiments.  Two other common techniques that molecular biologists use are PCR (in which we can look at an organism's  genes) and Western Blots (that allows us to look at certain proteins that are produced / expressed within cells).\n\nHistologists can take tissues and use immunohistochemistry (IHC) to detect the presence of certain proteins or other characteristics of the cells.  In IHC, antibodies which targe a certain cellular protein are applied to a preserved tissue and that antibody can then be detected by fluorescence or an enzyme-based coloration process.  \n\nThese are just a few of the techniques that we use to develop new drug therapeutics.  Be aware that the process to develop one drug from start to finish takes about 15-20 years and about $1billion, which might give you an idea of exactly how complicated it can get once you get into detail on the topic.

One good one:\n\nDNA replication is much more resistant to errors ... so DNA molecules can be *much* longer than RNA and still survive replication.  This supports the stable propagation of a much larger number of genes (tens of thousands of genes) from generation to generation without degradation.

Pros: work can get done quicker, things can get made better\nCons: you could have more phycopaths, murderers or worse TRENTONS!!!

Biotechnology is the use of biological techniques to develop products.  Typically, biotech companies are those that research microorganisms, such as bacteria, or cellular components, like DNA, to produce drugs, lab equipment, etc.\n\nBiochemistry is the study of the chemical compounds/processes that occur in living organisms.  If you think of your body, you can zoom down and find cells, then zoom down again and find proteins making your body run.  At that point, single molecules of Oxygen or Phosphate, for example, are vital.  That is the level of biochemistry.\n\nBioinformatics is the application of computer science to molecular biology.  In recent years, a huge amount of informatoin about gene sequences and proteins have been generated.  Bioinformatics is interested in using computers to get meaningful answers from all this information.  It's also the field I'm doing my graduate work in.\n\nHope this helps.

You will need to know both, since as time goes on, molecular behavior can be computer-predicted, the two fields are becoming inseparable. Prior to wetlab research, lenghty structural simulations will have been made. Bioinformatics will be more fun if you have a good knowledge of biochemistry.\n\nSupport novel transit solutions: http://www.hallisystem.bravehost.com

In genetics, hybridisation is the process of mixing different species or varieties of organisms. \n\nIn molecular biology hybridisation is the process of joining two complementary strands of DNA. \n\nIn chemistry, hybridisation is the mixing of atomic orbitals to form new orbitals suitable for bonding.

Many of the orignal studies were based on mutations in bacteria which halt growth or have other phenotypes, where it was found that mutations could be labeled into several groups, and that if bacteria from different groups mated, then the phenotype is restored.  From this it was deduced that the mutations were in coding regions for proteins that exist in a network ie A to B to C, and usually proteins like A and B were in a complex.  Today its a large part of cell and molecular biology to figure out if proteins are in complexes, and what the complex does.  Its not necessarily important that A and B are in a complex, but what that complex does; since that is the proteni function in cells.  So if A and C are in a complex, the complex has a certain function.  if B and C are in a complex, then there is a different function.  Drug companies have been exploiting this type of knowledge for a long time, but what is more impt is the understanding of how proteins interact with other proteins, and how they regulate cellular functions.  Once this is understood, then drugs can be rationaly designed.  Even then, however, it's not possible to guarantee patient efficacy.  \n\nWe just had a great lecture by Gordon Mills, an expert in the PTEN protein pathway, and he talked about the dozens of drugs made against various members of this pathway, and noted that so far none of these drugs are effective in patients, although they work in the test tube and in mice.  So, drug discovery is a very difficult issue and takes billions of dollars for one drug to be delivered to market (and 10 years or more).

it is really taking genes from some animal and transplanting it into a new organism. The new organism can create the protien which you can extract. This can be useful in pharmacueticals because yo can create protiens to implant into meds for saving lives It is also useful in creating drugs and antibiotics

Advantages-  Blood transfusions would come from your clone\n             and not strangers.\n\n             Chance for you to weigh out your options.\n             Ever wonder what would have happened if you \n             would have taken a different path.  Your clone\n             could do it for you.\n\n             Organ transplant on hand.\n\nDisadvantages-  Its like playing God.  Just shouldn't be \n                done.\n\n                Clone could turn out to be an evil twin and\n                try to steal your life.  They are not \n                robots, ya know.\n\n                One of me is enough!

Do not go there.\nLeave the microorganisms in peace.\n\nIf you have not got the entire DNA structure mapped and well understood, you are asking for nothing but trouble.  You might end up with a pathogen which targets human nerve cells or muscle nerve discharges.  Write a sci-fi book about your idea and leave the experiments until you finish a college degree and have a much better idea of just how complicated the Big Picture really is.

there are plenty of sites on genetic engineering and i have listed one below but some things seem better with modification for instance pigs produce vast amount of phosphorous which screws up our environment with a modification they can be grown with a change in their saliva to prevent that which makes for a better greener world, we use plastic surgery to make changes for the better, some things need the change.

it is the organism whose genetic sequence is completly studied.\nnot pathogenic so evenif escap from lab not causes hazardous effect.\npresent easily everywhere and isolation is also simple \ngrow on simple media\ngeneration time is less

hi, i work 4 a book company, and 1 of our regular books is on cell and molecular biology, if you email me, i can probably give you an answer on exactly what ur question is.
