This is the series of blocks Amino acid substitution matrices (BLOSUM), all of which are derived based on direct on direct observation for every possible amino acid substitution in multiple sequence alignments.
A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current.[1] In direct current (DC) circuits, this product is equal to the real power (active power) [2] in watts.
exists and is an alternate of . I'm assume by VA you mean Volt-Amperes. VA is a measurement for Reactive Power. In simplest of ways you can think of 10 VA as 10 watts. Usually VA is used for transformers to denote how much electrical energy is being transformed.
