Maize genotypes that carry the Hm1 gene, which encodes an enzyme that can metabolize and thereby detoxify HC toxin are resistant to C. carbonum.

#Unit 3. Fundamental Processes

In about half the polypeptides, the methionine at the terminus is removed by an aminopeptidase, which creates a new terminus from R2 (originally the second amino acid incorporated into the chain). When both steps are necessary, they occur sequentially. The removal reaction(s) occur rather rapidly when the nascent polypeptide chain has reached a length of 15 amino acids.

Primers start with the sequence pppAG positioned opposite the sequence 3 '-GTC-5' in the template.

Atrial repolarization is not seen on a normal ECG because it is “buried” in the QRS complex.

#Unit 2. Cellular Organization

Core DNA has an invariant length of 146 bp the minimum length of DNA needed to form a stable monomeric nucleosome, and is relatively resistant to digestion by nucleases.

Genus Proteus can lose their cell walls and swell into irregular shaped cells called L forms.
