Which is a force is responsible for seafloor spreading?
D. condensation in the mantle
Answer:
No se producen consecuencias si las vitaminas se toman en el rango normal.
Explicación:
La caída del cabello, el malestar gastrointestinal, la fatiga y el daño leve a los nervios son algunas de las consecuencias que se pueden obtener si se toma demasiado selenio. Las vitaminas son esenciales para la salud porque nuestro cuerpo las necesita para crecer y desarrollarse. Si estas vitaminas se usan en un rango normal, causan un buen efecto en el cuerpo, pero si tomamos demasiadas vitaminas, causa toxicidad y conduce a una serie de enfermedades. Entonces, si la concentración de vitaminas está en un rango normal en la leche desnatada, tiene un buen efecto en nuestra salud, de lo contrario, causa un problema.
What is this gizmo that you are talking about
DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?
A) The purines would be separated from the deoxyribose sugars.
B) The pyrimidines would be separated from the deoxyribose sugars.
C) All bases would be separated from the deoxyribose sugars.
D) The two strands of the double helix would separate.
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Answer:
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Explanation:
The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.
Eukaryotic cells do not have a nucleus. The nucleus is where DNA, your genetic material, is usually stored. Prokaryotic cells do not have a nucleus. The DNA just floats around the cell instead of staying in one designated area.
