a) Denaturation at 94°C, for 0.5 min

b) Primer annealing at 55°C for 1.5 min

c) Extension at 72°C for 1 min

Mafia hypothesis – In Brood parasitism

Cuckoos or cowbirds check their host’s nests and destroy all eggs if their owner is not present. If the parasite egg has been removed, they destroy the host’s nest and kill or injure the nestlings.

#Unit 1. Molecules and their Interaction Relevant to Biology

1. Glucogenic amino acids- which are degraded to pyruvate, α-ketoglutarate, succinyl-CoA, fumarate, or oxaloacetate and are therefore glucose precursors

2. Ketogenic amino acids- which are broken down to acetyl-CoA or acetoacetate and can thus be converted to fatty acids or ketone bodies
