We have studied a high copy number mutant of the ColEl-derived cloning vehicle pBGP120 (Polisky, Bishop and Gelfand, 1976). The mutant plasmid, pOPl, and its derivatives, such as pOPlA6, comprise about 30% of intracellular DNA, compared to about 5% for the parent, pBGP120 (Gelfand et...
Would a change in the nucleotide sequence of DNA change the structure of a protein? A.) One base equals one amino acid, so if there is a change in a base, it changes the amino acid, too. B.) A change in the DNA would ...

Estrogen, androgen, and glucocorticoid receptors function as hormone-responsive transcription factors that modulate gene expression by attaching to specific DNA segments known as estrogen, androgen, and glucocorticoid response elements, respectively. These elements are by characteristic nucleotide sequence motifs...
A change of the DNA in an organism that results in a new trait is known as a?IMutations:A mutation is defined as any change to the sequence of bases in DNA. This could be as small as a one base substitution (A gets switched with C) or as large as missing a whol...
human single-nucleotide variation had significant effects on activity at ~15.2% of off-target sites analyzed. CHANGE-seq is a simplified, sensitive and scalable approach to understanding the specificity of genome editors. This is a preview of subscription content,access via your institution...
Mutation Permanent change in the sequence of DNA. How can mutations affect an organism? Mutations can cause a cell to produce an incorrect protein during protein synthesis. As a result, the organism's trait, or phenotype, may be different from what it normally would have been. BUT a mutation...
Several approaches to this technique have been published, but these methods generally require single-stranded DNA (ssDNA) as the template1–4 and are labor intensive or technically difficult. Our QuikChange Lightning Site-Directed Mutagenesis Kit allows site- specific mutation in virtually any double-...

Furthermore, our results showed that mitochondrial DNA is not a reliable proxy for nuclear genome diversity, and its use in spatial conservation planning might lead to ineffective initiatives. Finally, we estimated that the extent of genetic diversity covered by protected areas will dramatically ...
