... (-) strand synthesis. Fine-tuning of the efficiency of the strand-transfer processes may be modulated by many other features, including the local sequence and structure of the core body TRS and ... analysis on total cellu- lar RNA (Figure 7). We used a (-) strand N gene probe that anneals to both genomic RNA and all sg (+) strand mRNAs. We included RNA from MHV-infected cells to obtai...

... obtain δ ( λa + b ) = λδ ( a ) + δ ( b ) (2:8) for all a , b ∈ A and all λ ∈ T . Putting a = b = 0 and replacing c and d by 2 n c and 2 n d, respectively, in (2.2), we get     1 2 2n f (2 2n cd) ... Hence, δ(λa)=δ  λ |λ| |λ|a  = λ 2 |λ| 2 δ(|λ|a)= λ 2 |λ| 2 |λ| 2 δ(a)=λ 2 δ(a ) for all a ∈ A and all lÎℂ (l ≠ 0). This means that δ is quadratic homogeneous. Replacing c and d...
