What does it mean when two strands of DNA in the double helix are antiparallel? What would the end of the double helix look like if the strands were parallel? How are base pairs important in the double helix structure of DNA? Where do hydrogen bonds form in the DNA double helix? How d...
What are the main structural features of B-DNA? How do the bases bond together in DNA? What does a DNA-binding protein do? How many strands make up a DNA structure? What is the structure that allows DNA to replicate? What is the structural feature that allows DNA to replicate?
Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). See how cells compare along a relative scale axis with other molecules, tissues, and ...
DNA means "Deoxyribonucleic Acid," "Does Not Apply," and "Did Not Attend." Deoxyribonucleic Acid DNA, or deoxyribonucleic acid, is the hereditary material found in cells of all living organisms. It is inherited from parents - half from the mother, and half from the father - and determines...
How Does PCR Work? A polymerase chain reaction requires two types of reagents, DNA polymerase and primers, and the process of thermal cycling. These ingredients make possible the chain reaction that exponentially copies the starting DNA sample. ...
This being is also said to be a self — whatever the self is that engages wholesale in “self-organization.” It does so in part by sponsoring many partial and subordinate “selves,” as when one speaks of self-organizing neural networks, self-organizing chromosome territories, self-organizing...

aWhen DNA were heated to certain temperature, the absorption value at 260nm would increased sharply, which indicates that the double strand helix DNA was separated into single strand. 当脱氧核糖核酸被加热了到某一温度,吸收价值在260nm会尖锐增加,表明双链螺旋脱氧核糖核酸被分离了入唯一子线。[translate...
When these lectures were given, the DNA molecule itself had already been discovered, but the double helix structure was yet to be found, along with much of our modern understanding of how this blueprint for life works. And yet the stability of the DNA molecule in the cell is directly due...
