The Replisome

31.2K
DNA replication is carried out by a large complex of proteins that act in a coordinated matter to achieve high-fidelity DNA replication. Together this complex is known as the DNA replication machinery or the replisome.
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...

Maxam-Gilbert Sequencing

10.5K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Translesion DNA Polymerases02:10

Translesion DNA Polymerases

9.4K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

DNA Replication

DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied.  After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

DNA as a Genetic Template02:05

DNA as a Genetic Template

22.3K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

  • To demonstrate the utility of a novel "universal template" for efficient library construction and analysis.

Main Methods:

  • A single DNA template incorporating deoxyinosine was designed for indiscriminate base-pairing.
  • Photocleavable linkers and direct encoding by reactant DNA were integrated into the system.
  • The universal template was utilized for library synthesis, target selection, and hit decoding.

Main Results:

  • Successful construction of a complete DNA-encoded library using a single universal DNA template.
  • Demonstrated efficiency in directing multiple chemical reactions with varied reactant DNAs.
  • Validated capabilities in library synthesis, target selection, and hit decoding.

Conclusions:

  • The universal template method provides a general and straightforward approach for preparing diverse DNA-encoded libraries.
