How MRNA leaves the nucleus after copying DNA?
nucleic acids
What is the process of isotopes breaking down and emitting particles such as alpha or beta to form a new substance?
Radioactive decay is the process in which a nucleus of an unstable atom loses energy through ionizing radiation. When this happens, one of its neutrons breaks down into a proton and an electron. The electron then leaves the atom as a beta particle.
What is a nuclear polyhedral virus?
This virus' image, using an electron microscope, shows an inclusion which appears to be similar to a nucleus. (Viruses have strands of RNA or DNA but no nucleus.) That is where the "nuclear" originates from. Polyhedral means that the virus has many sides. This is one of three shapes that viruses show. It affects the Wattle Bag Worm, the Korean Gypsy Moth, and cabbage leaves.
What macromolecules leaves the nucleus of a eukaryotic cell through the pores in the nuclear membrane?
mRNA (messenger RNA) is the macromolecule that leaves the nucleus of a eukaryotic cell through the pores in the nuclear membrane. This mRNA carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.
What is the equation for uranium decay?
Uranium-237 will undergo beta minus decay to neptunium-237 according to the following equation: 92U237 => 93Np237 + e- + 0.519 MeV At the risk of being a bore, a neutron in U237 undergoes a weak interaction-mediated change into a proton and an electron. The electron will be ejected from the nucleus immediately. Along with the electron, which leaves with a lot of kinetic energy, we'll see an antineutrino and the decay energy (0.519 MeV).
What are ground and excited states?
In an atom, the electron or electrons have a certain normal distance from the atomic nucleus, and when they are at the normal distance, that is described as the ground state. If energy is added to an electron it will move further from the nucleus, or depending upon the amount of energy, may leave the atom entirely. If it moves further from the nucleus it is in an excited state. If it leaves the atom it is ionized.
Where does RNA go when it leaves the nucleus?
it goes to the nucleus
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What never leaves the nucleus?
DNA is the genetic material that never leaves the nucleus of a cell. It carries the instructions necessary for synthesizing proteins and controlling cell activities.
What surrounds the nucleus and controls what enters and leaves the nucleus?
The nucleolus .
When sunlight excites electrons how do the electrons change?
Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.
What leaves the nucleus and moves to the cytoplasm?
protein
Does moss leaves have nucleus I don't know?
Each and every plant on planet earth consists of nucleus. Therefore, Moss leaves also have a nucleus which becomes a degenerated nuclei at the time of maturity.
Where does mRNA go after it leaves the nucleus?
After mRNA leaves the nucleus, it travels to the ribosomes in the cytoplasm where it is used as a template to make proteins through a process called translation.
What surrounds the nucleus and controls and what enters and leaves it?
The nucleolus .
What is the identity element for multiplication?
An identity element is an element of a set which leaves other elements unchanged when combined with them. For multiplication, the identity element is 1 .
When an atom loses an electron what happens to the atoms charge?
it gets a postive charge hope this helps good luck
