It depends on the organism, they all vary, they can reach up to 90% but I’m not sure so pick C:70%
Answer:
The key difference between prokaryotic and eukaryotic ribosomes is that the prokaryotic ribosomes are 70S particles composed of 50S large subunit and 30S small subunit while the eukaryotic ribosomes are 80S particles composed of 60S large subunit and a 40S small subunit
Explanation:
Answer:
Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).
