根据最后一段中“So this mechanism is evolutionarily conserved from insects to humans and, we believe, opens up an entirely new field of thinness(因此,我们相信,从昆虫到人类,这种机制在进化上是保守的,并且开辟了一个全新的瘦身领域。)”可推知,研究者对新的研究方向持乐观态度,故选A。 反馈 收藏 ...
An d I'm not talking about the pants you wore in college but can't fit into anymore.No, skinny g-e-n-e-s genes are factors foun d in folks who are naturally slim. An d researchers have just identified one that appears to tell the body's tissue to burn more fat.“We all know...
The hereditary material of all multi-cellular organisms is the famous double helix of deoxyribonucleic acid (DNA). This contains all of our genes. DNA, itself is made up of four chemical bases, pairs of which form the "rungs" of the twisted, ladder-shaped DNA molecules. These four molecule...
Gene editing is the ability to manipulate – or control – DNA. And in case you didn'tknow, DNA is short for deoxyribonucleic acid – this is a substance in the cells of animalsand plants that contains genetic information. And a gene is...

【题目】Editing humans'DNAIF you could change your child's DNA in thefuture to protect them against diseases, wouldyou? It could be possible because of technologyknown as CRISPR-Cas, or just CRISPR.CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part ofDNA;...
Gene silencing by RNA interference is being used routinely to study gene function in cultured mammalian cells. While this approach has been extremely powerful, it does not allow a critical evaluation of how genes function within the whole organism.
Recent technological advances have now largely overcome these issues, and multiple mRNA vaccine platforms against infectious diseases and several types of cancer have demonstrated encouraging results in both animal models and humans. This Review provides a detailed overview of mRNA vaccines and considers ...
The paradox has puzzled scientists because more cells lead to greater replications (复制), which increases the possibility of the body failing to detect damaged DNA or a faulty cell that can result in tumors(肿瘤). ...
