How do viruses get into bacterial cell?
A virus has proteins on its capsid that bind to living host cell. Once the virus has attached it enters the cell or inserts DNA/RNA into the cell.
What are the Parts of the virus and the human cell that bind together?
The spike proteins on the surface of the virus bind to specific receptors on the surface of human cells. For example, in the case of COVID-19, the spike protein of the virus binds to the ACE2 receptor on human cells, facilitating entry of the virus into the cell.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
How does a virus know what cell to enter?
A virus enters a cell by recognizing specific proteins or receptors on the surface of the target cell that it can bind to. These proteins or receptors are like a lock and key mechanism that allows the virus to gain entry into the cell. Once attached, the virus can then inject its genetic material into the cell to begin the infection process.
What are proteins from outside a cell that stimulate it to divide are called?
Proteins from outside a cell that stimulate it to divide are called growth factors. These proteins bind to specific receptors on the cell surface, triggering intracellular signaling pathways that promote cell division and proliferation.
What chemicals that coat the virus and keep it from making you sick?
Antibodies are proteins produced by the immune system that can bind to viruses and prevent them from infecting cells. They act as a coating that can neutralize the virus and prevent it from causing illness in the body.
What recognizes and binds to substances outside the cell?
Cell surface receptors recognize and bind to substances outside the cell. These receptors are usually proteins located on the cell membrane and play a crucial role in mediating communication between the cell and its external environment.
Proteins in blood that bind to antigens?
Antibodies.
What part of the virus bind the receptor proteins on a cell?
check on Google, i don't like home work and i love that wiki lets you put random stuff that probably isn't right.
Why does a virus only attach to only one cell?
A virus attaches to a specific cell because it has proteins on its surface that can only bind to receptors on that specific cell. This binding is necessary for the virus to enter the cell and replicate. This specificity is determined by the structure of the virus and the receptors on the cell surface.
Enhancers must bind to the repressor protein?
Enhancers do not directly bind to repressor proteins. Enhancers typically bind to activator proteins, which in turn help recruit RNA polymerase to the promoter region of a gene, leading to gene transcription. Repressor proteins, on the other hand, bind to specific DNA sequences to inhibit gene transcription.
What do signal molecules bind to in cells?
Receptor Proteins
