What is node and nodal plane?
In molecular orbital theory, a node is a region in a molecular orbital where the probability of finding an electron is zero. A nodal plane is a two-dimensional surface through which no electron can pass, resulting in a node in the molecular orbital. Nodes play a crucial role in determining the shape and energy of molecular orbitals.
Which molecular property defines the location of electrons?
The electron density, or distribution of electrons around the nucleus of an atom, is defined by the molecular property known as electronegativity. Electronegativity is the ability of an atom to attract shared electrons towards itself in a chemical bond.
Why must you go through the process of changing DNA into rna?
In order to protect the DNA from potentially damaging reactions in the cytoplasm, the nucleus prevents the DNA from leaving it. Therefore it must be transcribed by mRNA, which can leave the nucleus.
How many electrons must be removed from a neutral 63Cu atom to completely ionize it leaving only a nucleus?
29 electrons must be removed from a neutral 63Cu atom to completely ionize it, leaving only the nucleus. This is because copper has an atomic number of 29, indicating the number of protons, which is equal to the number of electrons in a neutral atom.
Where are deoxyribonycleic acid found?
It is abbreviated and also more known as DNA, the molecular constituent of chromosomes in the cell nucleus.
The nucleus is enclosed by a double layered membrane that serves to?
monitor the substances entering and leaving the nucleus and separate the nucleus from the surrounding environment
The nucleus is enclosed by a double-layered membrane that serves to?
Monitor the substances entering and leaving the nucleus and separate the nucleus from the surrounding environment. for Plato it's (B) :)
What is the molecular base in a nucleus called?
nothing
The nucleus is enclosed by a double layer membrane that serves to what?
The double layer membrane surrounding the nucleus, called the nuclear envelope, helps to separate the genetic material inside the nucleus from the cytoplasm of the cell. It regulates the passage of molecules in and out of the nucleus and provides structural support to the nucleus.
Is it true that ribosomes that are made in the nucleus pass though the nuclear envolope before entering the ctoplasm?
Nucleus is surrounded by nuclear envelop.So they have to pass it.
Most of the ice in the comets nucleus vaporizes leaving only small what?
particle
Where can you get a labeled diagram of a nucleus?
There is really nothing to diagram, because a cell nucleus just contains chromosomes and nothing else, and the chromosomes are just long molecular chains which are not arranged in any particular way, they are just stuffed into the nucleus.
Where does messenger RNA, or mRNA, travel to once it leaves the nucleus?
After leaving the nucleus, messenger RNA (mRNA) travels to the ribosomes in the cytoplasm of the cell for protein synthesis.
What can you infer about a high molecular weight protein that cannot be transported into the nucleus?
A high molecular weight protein that cannot enter the nucleus likely lacks a nuclear localization signal (NLS) required for nuclear import. This could indicate that the protein functions outside of the nucleus or interacts with other cellular structures. Alternatively, post-translational modifications may hinder its nuclear translocation.
What can you infer about large molecular-weight proteins that cannot be transported into the nucleus?
Large molecular-weight proteins that cannot be transported into the nucleus likely do not contain a nuclear localization signal (NLS) that is recognized by importins. These proteins may function primarily in the cytoplasm or at the cell membrane, where they carry out their specific roles without the need to access the nucleus.
Does the nucleus contain neutrons and electrons?
No, the nucleus contains protons and neutrons. Electrons are outside of the nucleus.
Describe the function and the molecular composition of the nucleus?
The nucleus is the central organelle of eukaryotic cells that contains the cell's genetic material, DNA. It governs cell activities by regulating gene expression and coordinating cell division. The molecular composition of the nucleus includes chromosomes (DNA and proteins), nucleoplasm, nuclear envelope, and nucleolus.
