The appropriate response is Nitrogenous Base. It is just a nitrogen containing atom that has an indistinguishable concoction properties from a base. They are especially vital since they make up the building pieces of DNA and RNA: adenine, guanine, cytosine, thymine and uracil.
Answer:
Bacteria has prokaryotic cells i. e. no true nucleus or membrane around the nucleus. They lack mitochondria, ribosome, lysosomes, endoplasmic reticulum, golgi bodies and cell wall.
Explanation:
Prokaryotes are the organisms which have no true nucleus while eukaryotes have true nucleus. True nucleus means that the membrane is present around the nucleus. Many organelles are also absent in prokaryotic cell which are present in eukaryotic cells.
The correct answer that would best complete the given statement above would be the first option. <span>An imbalance from homeostasis perspective is considered to be DISEASE. An imbalance indicates that homeostasis was not regulated properly in one's body and this would manifest in different kinds of health problems or disease. Hope this answer helps.</span>
Answer:
E. HER3, but not HER2 binds to its ligand, causing it heterodimerize with HER2. This activates HER2 tyrosine kinase which creates a GRB2 binding site.
Explanation:
The receptor tyrosine-protein kinase, also known as human epidermal growth factor receptor 3 (HER3), is a transmembrane tyrosine kinase receptor that doesn't have a kinase domain. HER3 binds to the HER2 protein (another receptor tyrosine kinase receptor) to form a heterodimeric complex. Conversely to the HER3 protein, HER2 lacks a ligand-binding domain. The HER2/HER3 complex triggers the activation of the HER2 kinase domain which then autophosphorylates and thus generates a binding site for the Growth factor receptor-bound protein 2 (Grb2).
