aWe each have a unique genetic(基因的,遗传的) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have...
But not all individual trees are susceptible. Dr. Amerson’s group has found markers that distinguish fungus-resistant stock from disease-prone trees. Using traditional breeding techniques, they are introducing the resistance genes into pines on test sites in America. Using genetic markers speeds up...
In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written...
How are genes transcribed in prokaryotes? Where is the information that directs protein synthesis found in DNA? How does DNA fit inside the cell nucleus? What is the control center of the cell that contains DNA? What is the part of the cell cycle in which DNA is synthesized?
we analyzed 20 fertile and 22 infertile obese individuals using Realtime-qPCR. By removing duplicated queries, we obtained 197 obesity-related genes and 102 male infertility-related genes from the OMIM database. Interestingly, theAPOBgene was found in common between the two datasets. REVEL identifi...
“What’s on your mind, doctor?” I asked. “We can talk freely here. The Captain is temporarily off the base and there is no recording equipment in this room. We are not being observed.” I shrugged. Where was this going? She continued: “Those things that you said in the lecture...

先张法预制板梁的工艺是在浇筑混凝土之前先进行预应力筋的张拉，并将其临时固定在张拉台座上，待混凝土达到规定强度(但不得低于设计标号的70％)时，逐渐将预应力筋松弛，利用预应力筋回缩与混凝土之间的粘结作用，使构件获得预应力。（ ）
