Such mutations can cause a gene to malfunction or inactivate (i.e., a tumor suppressor gene). The insertion of foreign genes into the host genome could also lead to constituent expression of previously silent bacterial/parasite genes that have been inserted. The insertion may also increase the ...
A Repeated Sequence (DNA) refers to duplicate DNA sequences that can vary in copy number between chromosomes, leading to polymorphism. Dynamic mutations in these repeat sequences can cause genetic diseases with unusual inheritance patterns, such as anticipation, by affecting gene function. ...
SNPs are locations that are compared to each other to see if mutations have occurred. Think of them as addresses on a street where an expected value occurs. If values at that address are different, then they don’t match. If they are the same, then they do match. For autosomal DNA mat...
The answer is there is no magic in the STRs included by panel at 1-12, 13-25, 26-37 and 38-67. It turns out I can see I have a couple red herring STRs in my 1-12 and 13-25 panel results which were throwing things off. These were very recent mutations that made me look ...

mutations83 Methods PERT model The input for PERT is scWGS read depth (Z) and called CN states for all bins (Ncells × Mloci) (Fig.S1a). Input CN states are obtained through single-cell CN callers such as HMMcopy49,84or 10X CellRanger-DNA51,52. PERT first identifies a set of...
Because DNA is the site of activity for many enzymes such as topoisomerase that metabolize mostly during fast replication processes, as observed in cancer, it is not uncommon for DNA ligands to be Topo inhibitors, such as m-AMSA. The relation structure-function and the role of the DNA binding...
Chi motifs play a key role in RecBCD dependent DNA double-strand break repair by homologous recombination in E. coli. Chi sites are responsible for the attenuation of the exonuclease activity of the RecBCD complex and the subsequent generation of 3′ single-strand DNA overhangs, a key ...
