DNA sequencing is the process of determining the sequence of nucleotide bases (As, Ts, Cs, and Gs) in a piece of DNA. Today, with the right equipment and materials, sequencing a short …

DNA sequencing involves three main steps: 1) using PCR to amplify DNA fragments, 2) introducing dideoxynucleotides that halt DNA strand elongation, and 3) employing a computer …

The development of DNA sequencing technologies, such as next-generation sequencing (NGS), has revolutionized the study of genomes by allowing researchers to sequence entire genomes …

Decoding messages is also a key step in gene expression, in which information from a gene is read out to build a protein. In this article, we'll take a closer look at the genetic code, which …

At the molecular level, evolution is largely the result of random mutations—small, spontaneous changes in the DNA sequence—that accumulate over generations.

How can pieces of DNA from different sources (such as a human gene and a bacterial plasmid) be joined together to make a single DNA molecule? One common method is based on …

Learn DNA cloning and recombinant DNA Overview: DNA cloning Restriction enzymes & DNA ligase Bacterial transformation & selection

DNA questions Google Classroom Microsoft Teams The leading strand of a DNA molecule has the following sequence: 5’-CGCATGTAGCGA-3’

We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. By finding recombination frequencies for many gene …

Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized …
