内容简介罗氏公司（Roche）推出了一种全新的高通量测序技术，名字叫“SPX”技术，是“Expansion Technology”的缩写。通过给4种碱基加上长的链子，链子上带特定序列信号，再在 DNA ...

All of the information needed to build and maintain an organism — whether it's a human, a dog, or a bacterial cell — is contained in its DNA. DNA molecules are composed of four nucleotides ...

Because gene-level mutations are more common than chromosomal mutations, the following sections focus on these smaller alterations to the normal genetic sequence. Base substitutions are the ...

A DNA sequence is a specific lineup of chemical ... called restriction fragment length polymorphism. Because this process was extremely time consuming and required a great deal of DNA, new methods ...

DNA is the molecule that holds the instructions ... Genomic sequencing Genomic sequencing is the process by which the sequence of nucleotide bases is determined for individual genes or even ...

In step 2, the gene fragment is integrated into a circular piece of DNA, called a plasmid, which is the main delivery vehicle into the cell and contains an antibiotic resistance gene for plasmid ...

Transcription is the process by which the genetic information in DNA is copied into a complementary RNA strand. RNA polymerase enzymes read the DNA sequence and synthesize messenger RNA (mRNA) ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).

The DNA Sequencing Industry has rapidly transformed into one of the most crucial areas of biotechnology. What was once a time ...
