What Are Telomeres? Let’s start by level-setting on a few genetic concepts that will help you understand how certain lifestyle choices and habits can have an impact on aging. You may have heard DNA referred to as the building block of life, as it is found i... ...
As previously mentioned, telomerase exerts its function by maintaining the length of telomeres present at the end of chromosomes that shorten with every cell division. Telomerase is usually not active in somatic cells, as they are mortal and die out after around 50-70 divisions. This occurs as ...
The human body contains hundreds of different types of cells that are important for our daily health. These cells are responsible for keeping our bodies running each day such as making our hearts beat, brains think, kidneys clean our blood, replace our skin cells as they shed off, and so o...
Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as ...
aIn America, molecular geneticist Bill Andrews has discovered a supplement that he believes will reprogram cells so that they will live forever. The supplement keeps telomeres from shortening as we age. Scientists believe that when telomeres – the strings of DNA that reside at the end of each ...

They describe creating 1565 different clocks based on different subsets of a universe of 529 proteins. In my opinion, their most important work combines biochemical knowledge with statistical algorithms. The work using statistical algorithms alone are much less interesting, for reasons detailed in the ...
What happens to telomeres during DNA replication? What happens during the elongation step of DNA transcription? During which part of the cell cycle does DNA replication occur and why is it important? a. Cell Cycle: Metaphase Reason: New genetic information causes the chromosomes to line up in ...
Why is exercise important for preventing problems like osteoporosis? Why do cells have telomeres? Why do telomeres get shorter every time a cell divides? What counteracts this shortening? What are the causes of old age? Provide some insight relative to cel...
Telomeres are the caps at the end of each strand of DNA, they are like the plastic tips at the end of a shoelace and prevent the strands of DNA from unravelling. Telomeres get shorter each time our cells divide until the strands at the end of DNA lose their protection. Astragalus can ...
