It is in every cell (细胞) of our bodies. It carries important 1.(information) about our genetic history (史). DNA tests can help us understand ourselves. Twenty 2.(pupil) from Atlanta, the US, took one of these tests.Last fall, they studied 3.(life)science. During their study, ...

In 1976, Maxam and Gilbert developed a technique in which DNA is chemically treated to break the chain at specific bases; following electrophoresis of the cleaved DNA, the relative lengths of the fragments—and thus the positions of specific nucleotides—can be determined and the sequence inferred...

DNA is the whole “map" of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.People have been trying to understand the human body for a ...
Prior to sequencing, the DNA library must be attached to a solid surface and clonally amplified to increase the signal that can be detected from each target during sequencing. During this process, each unique DNA molecule in the library ...

“snips”) are single base-pair changes in DNA that occur at specific places in the genome. For example, most individuals carry the C nucleotide at a specific base position in the genome, but in a minority of individuals this is replace...
