How can you use “excision” in a sentence? Here are some example sentences to help you improve your vocabulary:
Near the end of endo-replication in Spirotrichs many transposons and transposon-like sequences are eliminated by precise excision (Internal Eliminated Sequences or IESs [ 23 ] ). Excision directly precedes massive chromatid fragmentation and de novo telomere formation ("chromosome healing" [ 9 ] ) and the degradation of IESs and of "spacer" DNAs that lie between blocks of sequences destined for different MAC chromosomes.
However, when the reporter mice were crossed to β-actin-Cre transgenic mice [ 23], which express Cre constitutively in most or all cells including those in the early embryo, the resulting doubly transgenic embryos displayed apparently ubiquitous expression of EYFP or ECFP (Figure 2), indicating efficient excision of the floxed stop sequence.
Individual phage plaques were incubated in 400 μl SM buffer overnight and then used for excision.
Although the naïve/memory phenotype of T cells has previously been investigated in RA in numerous studies using CD45RA and CD45RO expression as markers of naïve and memory cells, respectively, that approach has suffered from the limitation that large numbers of CD45RA +CD8 +T cells are actually effector memory cells [ 10 13 ] . The CD45RA/CD45RO oversimplification has also resulted in rather confusing conclusions regarding T-cell homeostasis, such as defects in primary T-cell homeostasis based on reduced T-cell receptor excision circle (TREC) levels in naïve CD4 +T cells (defined as CD45RO -) in RA patients [ 14 ] . Our findings suggest that reduced TREC levels in the CD45RO -CD4 +T-cell population may not be due to a reduction in TRECs in naïve cells but rather to reduced TRECs in the CD45RA +CD45RO -CD62L -effector memory CD4 +T cells.
The dorsal ectoderm or BCNE is fully specified as anterior neural ectoderm, as excision of this region led to headless embryos, and explants differentiated into neural tissue in culture, even when the formation of any mesodermal cells was blocked by interference with nodal signaling (Kuroda et al.
