mRNA
mRNA (messenger RNA)
translation of mRNA occurs in the cytoplasm
Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to opposite sides of the nulceus. Spindle fibers form a bridge between the ends of the cell. the Nuclear envelope breaks down.
DNA replication takes place during the synthesis phase of the cell cycle. The cell also forms a second centrosomeduring this phase.The synthesis phase is often written as S phase. It occurs after the first growth (G1) phase, and therefore about midway through interphase.At the start of the S phase, each chromosome has only one DNA molecule, but by the end of the S phase each has two, which, barring copying errors, are genetically identical, i.e. they have identical base sequences.The doubling of the DNA and the centrosome constitute preparations for a subsequent cell division (mitosis or meiosis). A cell that is not due to divide will not go through an S phase.During the synthesis stage of the cell cycle, a cell makes (replicates its own) DNA.

The nucleus is the control center of the cell, containing genetic material (DNA) that governs cell activities like growth, metabolism, and reproduction. It regulates gene expression and plays a crucial role in cell division.
The number of protons in the atom's nulceus.
Fungi have a cell nucleus. Like all eukaryotic organisms, fungi have cells with a distinct membrane-bound nucleus that contains their genetic material. The nucleus is responsible for regulating the cell's activities and storing the DNA.
It keeps info. the cell might need, otherwise it is the organizer
Yes, electrons have a negative charge while protons have a positive charge. Opposite charges attract each other.
Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to opposite sides of the nulceus. Spindle fibers form a bridge between the ends of the cell. the Nuclear envelope breaks down.
Eu stands for true and karyo stands for nucleus. This can be used to help remember the difference between a eukaryote and a prokaryote. The pro in prokaryote stands for before and again karyo stands for nulceus. So prokaryotic cells come before the eukaryotic cells. And Eukaryotic cells have a nucleus while prokaryotic cells DO NOT have a nucleus.
The neurotransmitter that has been thought to be deficient is enkephalin. The striatal neurons in the caudate and putamen degenerate, causing decrease release of enkaphalin, leading to decreased activity of the indirect pathway of the basal ganglia. There is decreased inhibition on the globus pallidus externus, leading to increased inhibition of the subthalamic nulceus. This inactivates the indirect pathway, leading to hyperkinetic movements.
The mass number is the sum of the amounts of protons and neutrons in the nulceus of an atom. The reason we can get away with calling the tiny nucleus the key for the mass (remember the nucleus is made up of protons and neutrons) is because it is like over 99% of the mass of the atom (empty space and electrons have no significant mass). So, lets take the element carbon. Carbon will always have 6 protons, and around 98% of the world's carbon has 6 neutrons (this is due to natural variation). So 6+6=12. For the large majority of naturally occurring carbon, the mass number is 12.
