Defective Telomeres Linked To Diseases And Cancer

The document discusses two medical research studies. The first study investigates telomeres, the protective structures at the end of chromosomes, and finds defective telomeres are linked to diseases like cancer. The second describes a new more efficient method for making RNA molecules using robotics that could speed up research exponentially. The student observes both studies have important clinical applications, with telomeres key to future cancer research and the new RNA technique allowing diagnostics and therapeutics.

The second one Dr. Sousa thinks this new method to make RNA molecules that are chemically diverse will speed up research exponentially. In my humble opinion Dr. Sousa is too optimistic but, if he is right, biological sciences will benefit most. Until now make RNAs to develop diagnostics and therapeutics has been limited by existing technology. The interest in this is because RNAs are molecules that can be used to make therapeutics, sensors and diagnostics. GENETIC MATERIAL REPLICATION By: J. Felipe Gonzalez F. MOLECULAR BIOLOGY Teacher: Lina Martínez
Defective telomeres are now being linked to dozens of diseases, including many types of cancer: Telomeres are the structures that prevent the DNA strands makes chemically bonds to other strands, i.e. the chromosomes would merge and that would be lethal for the cell. The researchers are amazed about how complex is the biology of telomeres, and the high number of factors “they are finding that are essential to the preservation of telomeres and, above all, the precise coordination that is required between them all.” STUDENT OBSERVATION In my opinion what they are investigating is very important and will be will be a key issue in the future research, because they talk about topics of great interest for modern science like are cancer therapy and ageing. INTRODUTION In recent years not only their relation to ageing has been confirmed; also defective telomeres seem to be linked to a lot of diseases even with some types of cancer, this is very important for the future medicine. The importance of investigating these structures is to improve diagnoses and develop possible treatments for many diseases. Telomeres, in the opinion of these researchers, will become increasingly important in clinical studies. Different types of RNAs perform different functions, such as silencing a gene or regulating a plethora of processes in cells. The new method described by Dr. Sousa and his colleagues in Nature, which includes robotics, will speed up research exponentially. This is desirable for studies of RNA structure and function, and for design of applications that could be used to diagnose and treat diseases. This new technique allows the researcher make RNA molecules that are chemically diverse. Revolutionary method of making RNAs: Rui Sousa, Ph.D., professor of biochemistry in the School of Medicine at the Health Science Center is a co-author on the paper with colleagues from the National Institutes of Health, the University of Colorado, said that “RNAs are molecules that can be used to make therapeutics, sensors and diagnostics, for which there is a growing market”. He and his colleagues describes a new, more efficient method of making ribonucleic acids (RNAs). "This new technique allows a researcher to make RNA molecules that are chemically diverse,“ and they think this new method, will speed up research exponentially. STUDENT OBSERVATION Dr. Sousa and his collages propose a new method for making RNA in a more effective way, that will help a lot in my opinion because of what the told us at the beginning “RNAs are molecules that can be used to make therapeutics, sensors and diagnostics“.

TELOMESRES Telomeres are the ending regions of a chromatid, their presence protects the genes before them on the chromosome from being truncated instead. Defectivetelomeres arenowbeing linkedto dozensofdiseases,including manytypesof cancer:
Theresearchersinvestigate telomeres, this structuresare being linkedto diseases like cancer, this show us the great importance of telomeres and their function in the prevalence of the chromosome structure.
telomeres havebeen tightly preserved throughout the evolution in all cell lines, that indicates its importance. Theyprevent the fusion of chromosomes and the loss of genetic information each time a cell divides.
