A multiple sequence alignment (MSA) is a sequence alignment of three or more biological sequences, generally protein, DNA, or RNA. In many cases, the input set of query sequences are assumed to have...

Here the user will be able to use various sequence database similarity search tools such as FASTA, BLAST. Interactive as well as email submissions are available for each of these services. The results of similarity searches can be valuable in inferring homology, see 2can pages.

HR displayed a strong preference for the allelic template but also the capacity to interact with homologous sequence on heterologous chromosomes. ... When multiple potential templates are available, the choice may be governed by chromosome disposition prior to damage or, alternatively, damage may induce a homology search (10).

HR displayed a strong preference for the allelic template but also the capacity to interact with homologous sequence on heterologous chromosomes. Intra-chromosomal joining was predominantly, and possibly exclusively, microhomology mediated, a situation unique among organisms examined to date.
