Components of primary production

a. Gross primary production - Total organic matter production including reparatory loss during measurement of period.

b. Net primary production - Amount of matter accumulated by plant per unit area given time. 

 Gross – net = respiration

#Unit 3. Fundamental Processes

Two bases in the non-template strand of the –10 element (A11 and T7) flip out from their base-stacking interactions and instead insert into pockets within the s protein where they make more favorable interactions

#Unit 3. Fundamental Processes

The single replicator 245 bp required for E. coli chromosomal replication is called oriC. Two repeated motifs are critical for oriC function.

The 9-mer motif is the binding site for the E. coli initiator, DnaA, and is repeated five times at oriC.

The 13-mer motif, repeated three times, is the initial site of ssDNA formation during initiation.

Two Mechanisms Down-Regulate Signaling from RTKs

1. Phosphotyrosine phosphatases

2. Receptor-mediated endocytosis followed by degradation in lysosomes
