Answer: DNA contains the nucleotides guanine (G), cytosine (C), adenine (A), and thymine (T). RNA contains the nucleotides guanine (G), cytosine (C), uracil (U), and thymine (T). The difference between the two is that RNA contains uracil (U) rather than adenine (A).
The base pairs in DNA are adenine with thymine and guanine with cytosine. The base pairs in RNA are uracil with thymine and guanine with cytosine.
Although in many regions of the brain—particularly those that give rise to nuclear cell groups—neurons migrate without the benefit of glial guides, migration along radial glial fibers is always seen in regions where cells are organized into layers, like the cerebral cortex, hippocampus, and cerebellum.
Answer:
Glucose.
Explanation:
The cell membrane is made up of lipid bilayer and proteins are embedded or may span the lipid bilayer. The carbohydrates are present in association with lipids and proteins.
The artificial membrane has been prepared that are free from proteins. Small uncharged particles may easily diffuse through the membrane. Among the given molecules in the question water is the smallest molecule and diffuse out first through the plasma membrane. Ethanol is 2 carbon compound and diffuse after water than glycerol diffuses as it is a 3 carbon compound. Glucose is the largest molecule and diffuse last through the plasma membrane.
Thus, the correct answer is option (A).
V-gated ion channels, ligand-gated channels, sodium-potassium pump (Na-K pump), and passive or leakage ion channels.
