Answer:During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1).
Explanation:
Spina bifida; occurring in three forms listed from mildest condition to most severe; occulta, meningocele, myleomeningocele
They are condensing in the prophase stage
Answer:
They are the same
Explanation:
A membrane pump is a protein embedded within the cellular membrane which helps the cell transport molecules into and out of the cell. The proteins help the cellular membrane's job of being semi-permeable (allowing certain things in and out). Some molecules cannot travel directly through the cellular membrane (ions, large polar molecules) and have to rely on these proteins to get through the membrane. There are two types, channel and carrier protein pumps. Channel proteins allow for simple passive diffusion where as carrier proteins can allow for active transport as they shape/conform in regards to the molecule they are transporting. Both pumps are specific in what they transport.
Answer: Arginine and Lysine
Explanation:
Histones are protein that packs DNA into nucleosomes. It compose of Arginine and Lysine amino acids.
Lysine and Arginine are basic amino acids that aids the solubility of Histone in water and also aids the interaction of DNA and Histones.
