Answer:
Watson and Crick were able to develop a more accurate molecular structure because they had access to x-ray crystallography! Pauling didn't actually failed, he just did't have the same means!
Explanation:
By the way, is now known that the real discovery of DNA molecule was made by Rosalind Franklin. Any doubts you can send me a message!
Red blood cells do not have a nucleus.
It does not consist of a cell membrane or a cytoplasm.
It simply only transports oxygen around the body.
Pls mark me brainliest:)
Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
