How is the information contained in DNA transported out of nucleus?
Couldn't tell you, hun.
What is the spherical membrane-bound structure that contains DNA?
The nucleus.In a eukaryotic cell, the nucleus is more or less spherical, and surrounded by a double membrane perforated by pores that allow large molecules through. Inside the nucleus are the chromosomes, each of which has either one or (after DNA replication) two molecules of DNA.
How do matrials pass in and out of a cell nucleus?
There are small holes in the membrane of the nucleus called the nuclear pore. This allows small substances to pass into and out of the nucleus but traps large molecules like DNA and structures such as the nucleolus inside the cell nucleus.
Why can't DNA go to the ribosome?
DNA is too large a molecule to exit the nucleus through the nuclear pores.
What doesn't DNA ever leave the nucleus?
It's too big to get through the pores.
What does a nucleus contain besides DNA?
a nucleus contains chromatin fibres , then chromosomes ,and then the dna.
What are needed to transfer a gene through a DNA molecule?
Genetics engineering is needed to transfer genes through DNA molecules.
How does DNA go to exocytosis?
DNA does not go through exocytosis because it remains in the nucleus of the cell, where it is transcribed into messenger RNA (mRNA). This mRNA then exits the nucleus through nuclear pores and enters the cytoplasm, where it is translated into proteins. Exocytosis is a process used for the secretion of molecules, such as proteins and neurotransmitters, from vesicles in the cytoplasm to the outside of the cell. Thus, while DNA is crucial for encoding information, it does not directly participate in exocytosis.
The RNA type that diffuses through the nuclear pores to direct the assembly or synthesis of new protein molecules at the ribosomes in the cytoplasm is what?
Messenger RNA (mRNA) is the type of RNA that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs. It is transcribed in the nucleus and then travels through the nuclear pores to direct the assembly of new proteins at the ribosomes.
How does DNA molecules differ from daughter DNA molecules?
DNA molecules contain genetic information in a double-stranded helical structure, while daughter DNA molecules are formed during DNA replication and consist of two identical copies of the original DNA molecule. Daughter DNA molecules are produced through a semi-conservative process where one strand of the original DNA molecule is conserved in each daughter molecule.
How does varyfing the concentration of agarose used in gel affect the ability of the gell to separate molecule?
Varying the concentration of agarose in a gel affects the size of the pores within the gel matrix. Higher agarose concentrations create smaller pores, which are better for separating smaller molecules like DNA fragments. Lower agarose concentrations create larger pores, which are better for separating larger molecules.
Function of agarose in agarose gel electrophoresis?
Agarose is used in gel electrophoresis to separate nucleic acids (like DNA) by size, charge an other physical properties. Gel electrophoresis uses an electrical current to make particles move. For example, DNA is negative, so it'll travel towards to positive electrode of the gel box. Agarose has small pores through which a DNA can travel. Bigger fragments of DNA travel shorter distances, because it takes longer for them to navigate through the pores of the agarose gel. Identically sized pieces of DNA will travel the same distance, which is why you get bands (DNA with loading dye) after you run a a gel.
