(1)C.细节理解题.题目问关于基因和性格文章说了什么,根据第四段Although scientists agree that our genes influence our personalities,there is another question.How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still arguing them. So far, we...
Every human being has about 25,000 genes(基因). Your genes are part of yourDNA. They give our body instructions on how to develop. For example, if your genestell your body to build long, thin fingers, then you'll have long, thin fingers.Your genes come from your parents, and they ...
Your genes come from your parents,and they decide everything about you such as your hair color,your eye color,your weight,your height,and so on.Genes are still a bit of a mystery(神秘) to scientists,but they' re learning new things about them all the time. ...

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...
The Y appeared 300 million years ago and has since eroded into a dinky chromosome, because it lacks the mechanism other chromosomes have to get rid of damaged DNA. So mutations have disabled hundreds of its original genes, causing them to be shed as useless. The Y now contains only 27 ...

Housekeeping (HK) genes are ubiquitously expressed in all tissue/cell types and constitute a basal transcriptome for the maintenance of basic cellular functions. Partitioning transcriptomes into HK and tissue-specific (TS) genes relatively is fundamental
