What is the significance of flanking sequence variation? Flanking sequences appear to be responsible for supramolecular interaction, indicating that the kinase is capable of more than just catalytic activity under CaM control. Transposable elements (TEs) are defined as DNA sequences that are able to move from one location to another in the genome. TEs have been identified in all organisms, prokaryotic and eukaryotic, and can occupy a high proportion of a species’ genome. For example, transposable elements comprise approximately 10% of several fish species, 12 …Here, we present Flanker, a Python package that performs alignment-free clustering of gene flanking sequences in a consistent format, allowing investigation of MGEs without prior knowledge of their structure.

Although our results confirmed that the ... The Cre -loxP site-specific recombination system was first discovered in bacteriophage P1 ( Sternberg and Hamilton, 1981 ). Cre, a 38 kDa protein, recombines DNA between specific 34-bp sequences, called loxP. LoxP consists of a central 8-bp asymmetric sequence flanked by two identical 13-bp inverted repeats.

Floxing This figure depicts how Floxing is used in scientific research for spatial and temporal control of gene expression. In genetics, floxing refers to the sandwiching of a DNA sequence (which is then said to be floxed) between two lox P sites. The terms are constructed upon the phrase "flanking/flanked by LoxP".Features defining a pri-miRNA encompass more than just structure. Sequence motifs like UG and CNNC at the 5′ and the 3′ ends of the basal stem respectively can promote pri-miRNA cleavage by Microprocessor [46, 47]. A bulged GHG motif in the stem and UGUG motif in the loop also contribute to the processing efficiency [46, 48].
