Which Best Describes How Dna Fit Inside a Cell Nucleus

New viruses can be produced by copying the integrated DNA into RNA and packaging this into virus coat proteins the latter coded by the env genes on the virus genome. Prokaryotic Eukaryotic Cells Chapter Exam Instructions.


Cell Dna The Genetic Material Britannica

All cells whether prokaryotic or eukaryotic have a membrane that envelops the cell regulates what moves in and out selectively permeable and maintains the electric potential of the cellInside the membrane the cytoplasm takes up most of the cells volume.

. Chemical messengers or hormones bind tightly to their receptor proteins on the outside of a cell. The nucleotides hold a message inside DNA that is decoded by the cell to make proteins molecules that are needed for all cell structure and function. The helper T-cell will no longer bind to the B-cell and as a result the B-cell will not be activated.

Once inside a cell the RNA genome is copied into DNA by the reverse transcriptase specified by the viral pol gene and the DNA copy integrates into the host genome. Transmembrane proteins remain in the plasma membrane even though they are not attached to anything. During the humoral immune response helper T-cells activate B-cells through cell communication.

Ribosomes are found inside of prokaryotic cells rather than outside. All cells except red blood cells which lack a cell nucleus and most organelles to. For a vaccine which cell produces the protein encoded by the mRNA or the plasmid DNA can be a key issue because although for antibodies where the protein would likely need to be secreted for cellular immune responses of the Cytolytic T Lymphocyte variety the type of cell producing the protein and hence the cell type transduced by the.

Which of the following best describes the cell communication occurring in the figure above. Choose your answers to the questions and click Next to see the next set of questions. In organisms called eukaryotes DNA is found inside a special area of the cell called the nucleusBecause the cell is very small and because organisms have many DNA molecules per cell each DNA molecule must be tightly packaged.

More prokaryotic cells could fit inside a 1 cm cube than eukaryotic cells could.
