What are New Results of Human Genome Sequencing?

Scientists discover new results of human genome sequencing, which is expected to promote research on human diseases

Introduction: Recently, researchers at the University of Maryland School of Medicine discovered a new result of human genome sequencing. This progress is expected to promote future research aimed at understanding the impact of human genome variations on human diseases.


Is gene sequencing the only method of genetic testing?

Gene sequencing is only one of the methods of genetic testing. It is also called gene profile sequencing, which is an internationally recognized standard for genetic testing.


Recently, researchers from the University of Maryland School of Medicine (UMSOM) published a paper entitled "Haplotype-resolved diverse human genomes and integrated analysis of structural variation" in the journal Science, announcing a new achievement in human genome sequencing.

Genome sequencing


The researchers detailed the sequencing of 64 complete human genomes. This reference data includes individuals from all over the world, which can better capture the genetic diversity of human species. 

Among other applications, this work will enable population-specific research on the genetic susceptibility of human diseases and the discovery of more complex forms of genetic variation.


Twenty years ago, the International Human Genome Sequencing Consortium announced the first draft of the human genome reference sequence. 

However, this more comprehensive reference data set represents 25 different human populations around the world, which can better reflect the genetic differences from different populations and serve as a new reference for understanding human disease susceptibility.


On this basis, scientists have conducted multiple sequencing projects in the past 20 years to identify and classify genetic differences between individuals and reference genomes. These differences usually focus on small single-base changes while ignoring larger genetic changes. Now, current technologies are beginning to detect and characterize larger differences (called structural variations), such as the insertion of new genetic material. Compared with smaller genetic differences, structural variations are more likely to interfere with gene function.


The new discovery of "Science" magazine announced a new and more comprehensive reference data set obtained by combining advanced sequencing and mapping technologies. 

The new reference data set reflects 64 assembled human genomes, representing 25 different human populations worldwide. Importantly, each genome was assembled without the guidance of the first human genome complex. 

As a result, the new data set can better capture genetic differences from different populations.


Dr. Scott Devine said: "We have entered a new era of genomics, in which exciting new technologies can be used to sequence the entire human genome. These new technologies can provide larger and more accurate readings of DNA bases. Enables researchers to study previously inaccessible regions of the genome that are associated with human characteristics and diseases."


The Genome Resource Center (GRC) of the Institute of Genomic Sciences (IGS) is one of three sequencing centers, along with the Jackson Laboratory and the University of Washington, which use new sequencing technology recently developed by Pacific Biosciences to generate data. 

GRC is one of only five early access centers required to test the new platform.


Dr. E. Albert Reece said: "This landmark new study shows that we have a deep understanding of the basis of genetically driven health. This progress is expected to promote future developments aimed at understanding the impact of human genome mutations on human diseases. the study."

Microbiology FAQs. Course and Journal

Microbiology (Academic Subject and Medical Department) Meaning of Microbiology : Microbiology is one of the branches of biology. It is to study the morphological structure, growth and reproduction of various micro-organisms (bacteria, actinomycetes, fungi, viruses, Rickettsia, mycoplasma, chlamydia, spirochete protozoa and single-cell algae) at the molecular, cellular or population level. It is also a name of medical department that studies and applies the subject. It also studies physiological metabolism, genetic variation, ecological distribution and taxonomic evolution and other basic laws of life activities, and apply it to science in the fields of industrial fermentation, medical hygiene and bioengineering. Microbiology is a science that studies the laws of life activities and biological characteristics of various tiny organisms.   Discipline Name:     Microbiology Subject:     Biology Definition:     One of the branches of biology studying micro organisms

Ayurveda Ayurvedic Treatment Therapy Science

What is Ayurveda? Indian Ayurvedic Science and Therapy : Ayurveda is therapy, the science of life and longevity. It is an ancient Indian healing system that is widely popular around the world. It originated from the Atharva Veda in the Vedas. The Vedas is a very huge system of knowledge that is passed directly from God to great saints. The Vedas is also considered to be the manifestation of God himself. This knowledge is revealed every time it is created, so Ayurveda has an eternal relationship with God. Ayurveda's written records have a history of more than 5,000 years. It existed for thousands of years before the written records. It is the only oldest comprehensive health care system in the world, and its herbal system is still practiced to this day. This is referable as ayurvedic system. Maharshi Sushruta is said to have acquired Ayurvedic's original knowledge from the Brahma. Ayurveda's most important classics are "SushrutaSamhita", "Charak Samh

Banana Bunchy Top Virus Symptoms Prevention and Treatment

What is the harm of banana bunchy top disease? What are the symptoms? How to prevent it? Banana bunchy top disease is a devastating disease of bananas. The susceptible plants are dwarfed and do not bloom and form buds. Plants that are susceptible only at the present bud stage have few fruits and no commercial value.    The main symptom of the disease is dwarfing of the plant. New leaves are narrower, shorter, harder and straighter than one. The diseased leaves are brittle and bunched, with dense green or black stripes on the veins of intermittent and varying lengths. The pathogen is banana bunchy top virus.  The initial source of infection in the new banana planting area comes from poisonous seedlings, and the old banana area comes from diseased plants and their buds.  Long-distance transmission of the disease mainly depends on poisonous buds, and close-range transmission depends on banana cross-vessel aphid. Therefore, the peak period of disease is closely related to
