Summary
Genetic engineering enables recombinant spider silk production. Recursive directional ligation offers a modular method for controlling silk gene cassette size without disrupting sequences.
Area of Science:
- Biotechnology
- Genetic Engineering
- Materials Science
Background:
- Genetic engineering advances allow for the production of recombinant spider silks.
- Various cloning strategies exist, including concatemerization, step-by-step ligation, and recursive directional ligation.
Purpose of the Study:
- To describe recursive directional ligation as a method for producing recombinant spider silks.
- To highlight the modularity and control over genetic cassette size offered by this approach.
Main Methods:
- Utilizing recursive directional ligation for assembling genetic cassettes (monomers).
- Sequential ligation of monomers where junctional sequences do not interrupt key gene segments.
Main Results:
- Recursive directional ligation provides facile modularity in constructing spider silk genes.

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Viral Recombination
25.2K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Homologous Recombination
63.5K
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

Cloning of Dolly the Sheep
7.7K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Overview of Transposition and Recombination
19.4K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
