GENETICS: SCIENTIST VIDEOS

What's the Difference Between Genomics and Genetics?

Dr. Loren Skow, geneticist and Senior Professor at Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, leads us through the differences in studying genomes and genetics. A gene and a genome are not the same thing! He will also answer questions such as, How much DNA is in a genome? How many genes are on a chromosome? What exactly is inherited from mom and dad?

How is DNA Sequenced?

What exactly does the sequence of the genome tell us? Well, until it’s decoded, very little. The act of decoding is the first step in a journey to discovery. These questions, as well as how long a genome can be, is explained by Texas A&M geneticist and Senior Professor, Dr. Loren Skow.

What is the Human Genome Project?

In this video, Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, describes the process of sequencing the entire human genome. He further explains how this technology can be harnessed to understand diversity in our health. Along the way, he answers important questions about one of the most notable scientific accomplishments of the twenty first century.

As you watch consider the following questions:

  • Do you think the cost of this project was worth it?
  • How has the cost of genetic sequencing changed over time?
  • Have you taken advantage of this change by using one of the dozens of sequencing services available to the public and their pets?

The Importance of DNA Sequencing

Biomedical genomics is limited by the specificity of sequencing, but with time geneticists have become very skilled in analysis. In this video, Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, will show how genetic understanding can be used to illustrate the diversity in the code from one person to the next.

Genetics in Personalized Medicine

What if our medical treatment was tailored to our specific genetic makeup? Medicine of the future will be prescribed based on our genome. This effort has already begun with small studies and specific active ingredients. Here, Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, fills us in.

As you watch, consider the following question:
Besides medicine, what other sectors can take advantage of genomics?

Examples of Medical Genomics

In this video, Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, shows us specific pharmaceutical examples of genomics in action.

Comparative Genomics

Does size of an animal correlate to length of genetic code? How different is the human code to the code of other mammals? How can this technology be used to aid human health and animal survival?
Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, shares the science of comparative genetics and how the genome sequences of all species are used to further our understanding of health.

How Does Gene Therapy Work?

In this video, Dr. Loren Skow, geneticist and Senior Professor from Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, explains how CRISPRcas9 is used to alter the genetic code as an enzyme on the DNA strand. He also describes the ways in which it can silence a gene sequence or correct a mutation.
 

Genomic Phenotyping

How can we use the DNA of our ancestors to unlock the secrets of our past and our present? In this video, Dr. Loren Skow, geneticist and Senior Professor at Texas A&M’s College of Veterinary Medicine & Biomedical Sciences, describes the process of creating phenotypic predictions based on the sequencing and analyzing of genomes.

To fix an over-expressed gene, CRISPRcas9 does not "correct" its code, it the over-expression with a mutation
