They are best known for their role in regulating homeotic genes during development in flies and vertebrates. However, it is now realized that PcG/TrxG proteins function as master transcriptional ...

现在看看自己拿着手机的手，想不想感叹一句这五根手指简直是天生玩手机圣体，要是长成鱼鳍、马蹄，可怎么刷手机啊！手指不是五根也很酷啦~人和灵长目的手指脚趾都呈现五根，各种耗子、豺狼虎豹也是前肢五根手指，鳄鱼和一些蜥蜴也都是，那你有没有想过，为什么要五根手 ...

“You just can’t reduce something as complex as human exploration to a single gene,” he says, laughing. “Genetics doesn’t work that way.” Fortunately for me, I had to wander only a ...

The term 'post-genome' is increasingly being used in rallying calls to the research community to redouble efforts in understanding gene function and regulation in a world where the human genome ...

Most famously, Lewis was unraveling the bithorax complex and Nüsslein-Volhard and Wieschaus were doing their saturation screens for zygotic segmentation genes. But there was a lot more going on ...

Sep. 16, 2024 — CREME is a virtual laboratory that allows scientists to simulate specific decreases in gene activity. It offers a powerful new tool for identifying and understanding important ...

The purpose of this textbook is to present classical plant development in modern, molecular-genetic terms. The study of plant development is rapidly changing as genome sequencing projects uncover a ...

Oct. 28, 2024 — Using state-of-the-art technology, researchers have identified several specific steps needed for CRISPR to become active and perform its gene editing function. These preclinical ...

Some characteristics are controlled by a single gene, such as fur in animals and red-green colour blindness in humans. Each gene might have different forms, and these are called alleles.

Two new studies found that ancient human ancestors carried a surprising diversity of genes for amylase, an enzyme that breaks down starch. By Carl Zimmer As soon as you put starch in your mouth ...

Their new approach opens the possibility of controlling when and where genes are expressed in the body, for the benefit of human health and medical research, in ways never before possible.
