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, ...
Sanger sequencing is a method that yields information about the identity and order of the four nucleotide bases in a segment of DNA. Also known also as the “chain-termination method”, it was developed in 1977 by Frederick Sanger and colleagues, and ...
the ability to read genetic sequences is enormously valuable to biological research. Because differences in DNA and RNA sequences can distinguish organisms down to species and individual levels, sequencing is a powerful tool in forensics and may be used in the future to characterize various diseases...

These 4 Nitrogenous bases pair together in the following way:AwithT,andCwithG.These base pairs are essential for the DNA’s double helix structure, which resembles a twisted ladder. The order of the nitrogenous bases determines the genetic code or the DNA’s instructions. ...
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required...
阅读理解。 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. Peopl
DNA is a pattern,too.DNA也是一种模型。Your body uses this pattern to build itself.你的身体用这种模型来构建它自己。DNA is the "blueprint of life."DNA是生命的蓝图。DNA is fascinating!DNA很吸引人! Except for identical twins,除了同卵双胞胎,each living thing has its own unique DNA.每种生物...

A sequencing “library” must be created from the sample. The DNA (or cDNA) sample is processed into relatively short double-stranded fragments (100–800 bp). Depending on the specific application, DNA fragmentation can be performed in ...
