2、e discovery builds on earlier findings showed that a class of genes called splicing (胶接) factors is progressively switched off as we age. The research team found that splicing factors can be switched back on with chemicals, making aging cells not only look _31_ younger, but start to divide like youn

The chemicals _33_ splicing factors, which are progressively switched off as we age to be switched back on. Within hours, the cells looked

Most people by the age of 85 have experienced some kind of chronic illness, and as peo

Our data suggests that using chemicals to switch back on the major class of genes that are switc

7、t. These old cells were looking like young cells. It was like magic,” she said. “I repeated the experiments several times and in each case the cells rejuvenated. I am very excited by the implications and potential for this research.”As we age, our tissues accumulate senescent cells which are alive b

This is one reason why tissues and organs become susceptible to disease as we age. When activated, genes make a message that gives the _40_for the cell to behave in a certain way.
9、 Most genes can make more than one message, which determines how the cell acts.Splicing factors are crucial in ensuring that genes can perform their full range of functions.III.

10、D. Fill in each blank with the word or phrase that best fits the context.Cameron Buckner, assistant professor of philosophy at the University of Houston, argues in an article published in Philosophy and Phenomenological Research that a wide range of animal species exhibit so-called “ executive contr

But supported by a review of previously published research, Buckner

One way to address that, Buckner said, is to _47_exactly wha
