In addition, a total of forty casts were prepared in order to measure the angular dimensions. It was found that the basic measurements of all variables show high variations, but in only one variable, measurements were very inconsistent as evidenced by the large intra- and inter-observer errors. In terms of the angle dimension the results show that the range of variation was higher for the lateral angle and that the intra-observer error was found to be much lower for the medial angle than for the lateral one. The results show potential in the use of these methods in terms of repeatability, but also indicate that the metric assessment is prone to false application caused by the morphological variations of the individual landmarks.The bacterial Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)/Streptococcus pyogenes CRISPR-associated protein (Cas) system has been harnessed by researchers to study important biologically relevant problems. The unparalleled power of the CRISPR/Cas genome editing method allows researchers to precisely edit any locus of their choosing, thereby facilitating an increased understanding of gene function. Several methods for editing the C. elegans genome by CRISPR/Cas9 have been described previously. Here, we discuss and demonstrate a method which utilizes in vitro assembled ribonucleoprotein complexes and the dpy-10 co-CRISPR marker for screening. Specifically, in this article, we go through the step-by-step process of introducing premature stop codons into the C. elegans rbm-3.2 gene by homology-directed repair using this method of CRISPR/Cas9 editing. This relatively simple editing method can be used to study the function of any gene of interest and allows for the generation of homozygous-edited C. elegans by CRISPR/Cas9 editing in less than two weeks.Oxidativ
