Genome position and gene amplification

Different genome amplification mechanisms and duplicate gene expression in Liliaceae.

GenomePlex Whole-Genome Amplification.

INTRODUCTIONPCR-based whole-genome amplification (WGA) has the goal of generating microgram quantities of genome-representative DNA from picogram or nanogram amounts of starting material. This amplification should introduce little, or ideally no, representational bias. In contrast to other techniques for WGA, PCR-based methods are generally less affected by DNA quality and are more applicable t...

Primase-based whole genome amplification

In vitro DNA amplification methods, such as polymerase chain reaction (PCR), rely on synthetic oligonucleotide primers for initiation of the reaction. In vivo, primers are synthesized on-template by DNA primase. The bacteriophage T7 gene 4 protein (gp4) has both primase and helicase activities. In this study, we report the development of a primase-based Whole Genome Amplification (pWGA) method,...

Whole Genome Amplification and Branching Processes

Whole genome amplification is important for multipoint mapping by sperm or oocyte typing and genetic disease diagnosis. Polymerase chain reaction is not suitable for amplifying long DNA sequences. This paper studies a new technique designated PEP–primer extension preamplification for amplifying long DNA sequences using the theory of branching processes. A mathematical model for PEP is construct...

Genome amplification of single sperm using multiple displacement amplification

Sperm typing is an effective way to study recombination rate on a fine scale in regions of interest. There are two strategies for the amplification of single meiotic recombinants: repulsion-phase allele-specific PCR and whole genome amplification (WGA). The former can selectively amplify single recombinant molecules from a batch of sperm but is not scalable for high-throughput operation. Curren...
