Well in a chromosome, it looks like sort of a X. Two strands of DNA packed with proteins. The DNA found in the nucleus contains the genes that form alleles which code our traits. Our genotypes and our Phenotypes. There can also be a process called mitosis,or cell division. I find it easier to learn about mitosis first, because it has a better understanding of which part the chromosomes take place in.
MITOSIS:
Cycle of cell division. There are many more phases, but these are the main five.
- Prophase. Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle.
- Metaphase. Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.
- Anaphase. The paired chromosomes separate at the kinetochores and move to opposite sides of the cell. Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
- Telophase. Chromatids arrive at opposite poles of cell, and new membranes form around the daughter nuclei. The chromosomes disperse and are no longer visible under the light microscope. The spindle fibers disperse, and cytokinesis or the partitioning of the cell may also begin during this stage.
- Cytokinesis. In animal cells, cytokinesis results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus. In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells.
What else can I help you with?
Principle molecule that carries out the instructions coded in DNA?
The principle molecule that carries out the instructions coded in DNA is messenger RNA (mRNA). It serves as a template for protein synthesis by carrying genetic information from DNA in the nucleus to the ribosomes in the cytoplasm where proteins are assembled.
RNA that is a copy of DNA message that can enter the cytoplasm?
Messenger RNA (mRNA) is a copy of the DNA message that is transcribed in the nucleus and can be translated into proteins in the cytoplasm. It carries the genetic information from the DNA to the ribosomes where protein synthesis occurs.
What carries the information of DNA in the nucleus out into the cytoplasm of the cell?
mRNA
What carries information from the DNA in ther nucleus out into the cytoplasm of the cell?
mRNA
Role of mRNA during protein synthesis?
copies the genetic code from the DNA molecule and carries it to the ribosome
What carries the DNA message out to the cytoplasm?
mRNA
Which molecule carries the message from the DNA in the nucleus to the cytoplasm where the code is translated?
Messenger RNA (mRNA) carries the genetic information from the DNA in the nucleus to the cytoplasm where it is translated into proteins. This process is known as transcription, and it is a key step in gene expression.
RNA that copies the coded message from the DNA in the nucleus and carries the message into the cytoplasm?
Messenger RNA.
Rna that copy of the DNA message that can enter the cytoplasm?
mRNA (messenger RNA) is the RNA molecule that carries a copy of the DNA message from the nucleus to the cytoplasm. Once in the cytoplasm, mRNA is used as a template for protein synthesis during translation.
Carries the message of DNA to ribosomes?
mRNA (messenger RNA) carries the message of DNA to ribosomes. It serves as the intermediary molecule that transfers genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm where protein synthesis occurs.
What carries information from the nucleus to the cytoplasm?
Messenger RN is the RNA that transports information from DNA in the nucleus to the cell's cytoplasm. Its main function is transporting information from the DNA to the nucleus of the cytoplasm of the cell.
Principle molecule that carries out the instructions coded in DNA?
The principle molecule that carries out the instructions coded in DNA is messenger RNA (mRNA). It serves as a template for protein synthesis by carrying genetic information from DNA in the nucleus to the ribosomes in the cytoplasm where proteins are assembled.
What is the message that messenger RNA carries to the cytoplasm?
Messenger RNA is copied (transcribed) from DNA. It carries a special nucleic acid code (template) that is used by Transfer RNA to synthesize proteins. It takes three adjacent nucleic acids in the Messenger RNA template to code one Amino Acid in a protein.
RNA that is a copy of DNA message that can enter the cytoplasm?
Messenger RNA (mRNA) is a copy of the DNA message that is transcribed in the nucleus and can be translated into proteins in the cytoplasm. It carries the genetic information from the DNA to the ribosomes where protein synthesis occurs.
What carries information form the DNA in the nucleus out the cytoplasm of the cell?
The MRNA carries information from the DNA in the nucleus out the cytoplasm of the cell.
The molecule coded directly from DNA is represented by number?
The molecule coded directly from DNA is messenger RNA (mRNA). It carries the genetic information from the DNA in the cell's nucleus to the ribosomes in the cytoplasm where protein synthesis occurs.
The RNA species that carries the coded message specifying the sequence of amino acids in the protein to be made from the nuclueus to the cytoplasm is?
messenger RNA (mRNA) carries the coded message specifying the sequence of amino acids in the protein from the nucleus to the cytoplasm. It is transcribed from DNA in the nucleus and serves as the template for protein synthesis in the cytoplasm.
