Learn more.CAS can work with the spacer sequence, but the PAM sequence adds an extra level of precision and accuracy to the editing process. So, both in theory and in practise, the need for PAM weakens gene editing. Yes, it creates a problem. Because a PAM sequence isn’t always present in a gene of interest, which is what we are testing.Short Tandem Repeats. Short tandem repeats (STRs), or “microsatellites,” are tracks of tandemly repeated short (1 to 6 bp) DNA sequence motifs. STRs may occur in both intergenic and intragenic regions, including within genes, and account for approximately 3% of the human genome. The importance of position in defining the functional initiation site was shown by manipulating a cloned preproinsulin gene to produce an mRNA in which the "ribosome binding site" (i.e. the ATG initiator codon and flanking sequence) was tandemly reiterated: ribosomes initiated exclusively at the 5'-proximal copy in the tandem array (Kozak, 1983b).8 thg 12, 2021 ...
