What is a DNA-binding motif? Gene regulatory proteins: Each second thousands of genes are turned on and off in our bodies but how does each cell know when to turn on, or turn off (express or repress) a specific
What is a DNA sweep? DNA Evidence: In the modern world, the advancement of technology has resulted in the evolution of new techniques for identifying a criminal suspect. Analysis of DNA samples stands out as one of the best methods of identifying the key suspect of a crime. The analysis of...
The hunt for pathogenic mitochondrial DNA (mtDNA) mutations is often fueled by the seeming novelty of mutations that are either nonsynonymous or affect the protein synthesis machinery in patients. In order to determine the novelty of a detected mutation,
motif (PAM), a short sequence downstream of the target site. When it recognizes PAM, Cas9 checks the region upstream - if it locates the target provided by the gRNA, it will create a double-stranded break (DSB). DSBs incapacitate the virus because viruses lack their own DNA repair ...
The protospacer adjacent motif (PAM) is a shortDNAsequence (usually 2-6 base pairs in length) that is about 3-4 nucleotides downstream from the DNA sequence targeted by Cas9. Cas9 cannot bind to or cleave the target DNA sequence if it is not followed by the PAM sequence. ...
The DNA-binding homeobox motif was first identified in several Drosophila homeotic genes but also in fushi tarazu, a gene found in the Hox cluster yet involved in segmentation, not anteroposterior patterning [1]. Homeotic transformations are not seen in insect ftz mutants, and insect ftz genes ...

What is the Protospacer Adjacent Motif (PAM) Sequence? The protospacer adjacent motif (or PAM for short) is a short DNA sequence (usually 2-6 base pairs in length) that follows the DNA region targeted for cleavage by the CRISPR system, such as CRISPR-Cas9. The PAM is required for a Cas...
From a layman’s perspective, ‘leaf’ is a flattened, green-colored structure laterally attached to the stem. This perception may be too simple considering the remarkable diversity that leaves exhibit. As a prerequisite to their review on angiosperm leaf shape, Nicotraet al.[1] defined a leaf...
domain effector proteins achieve interference by complementarity betweenthe crRNA and the target sequence after recognition of the PAM (ProtospacerAdjacent Motif) sequence, which is adjacent to the target DNA . Theseribonucleoprotein complexes have been redesigned for precise genome editing byproviding a...
