The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...

For millennia, evolution has intrigued many great thinkers, prompting questions about how new traits emerge as species adapt over time. Then, attention shifted to natural selection and the inheritance ...

Thanks to increasingly efficient and affordable gene sequencing technologies, we can now chart our genetic blueprint in unprecedented detail. But what does each gene do? Of the roughly 20,000 genes ...

An affordable new BRCA gene test has hit the market, but who should take it? — -- A new genetic testing kit that hits the market today is the most affordable, and arguably one of the simplest, ...

As researchers work to understand the human genome, many questions remain, including, perhaps, the most fundamental: Just how much of the human experience is determined before we are already born, by ...

What Is the MTHFR Gene Mutation? The MTHFR gene mutation is a variation in the MTHFR gene. This gene normally tells your body how to make the MTHFR protein. You need this protein to process folate, ...

Humans love to play with their food—in fact, we’ve been doing it for thousands of years. In this episode of Crash Course Botany, we explore how we’ve learned to manipulate plant genetics, from ...

Lurking within the genomes of nearly all species--including plants, fungi, and even humans--are genes that are passed from generation to generation with no clear benefit to the organism. Called ...

The prothrombin gene mutation increases your risk of severe blood clots. Medications, regular checkups, and healthy lifestyle habits can help reduce this risk. The prothrombin gene plays a crucial ...

With no cure for Alzheimer’s disease, doctors have repeatedly stressed the importance of knowing your personal risk factors and doing everything you can to protect your brain as you age. In that sense ...

Trinity researchers have led a new collaborative study, combining large genetic datasets with satellite weather data and ...
