How does a chromosome control cell processes?
Chromosomes contain genes, which are sequences of DNA that provide instructions for making proteins. These proteins are essential for controlling and participating in various cell processes, such as cell division, growth, and metabolism. When a cell needs to carry out a specific process, it can activate the genes on its chromosomes to produce the necessary proteins.
The information necessary to make the proteins that regulate cell growth and division is contained in what?
nucleus
What do oncogenes normally encode for?
Oncogenes typically encode for proteins that promote cell growth and division. When these genes are mutated or overexpressed, they can drive uncontrolled cell growth, leading to the development of cancer.
Does cell division speed up when healing process nears completion?
The rate of cell division slows down,controls on growth are restored, and everything returns to normal.
When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
What is the misregulation of the proteins that control cell growth and division?
Cancer
What are the class of proteins that can override the inhibitory controls of cell division?
growth factors!
Growth and division in a cell are carried out by?
The production of proteins
Do plants have DNA and how does it contribute to their growth and development?
Yes, plants have DNA, which is a molecule that carries genetic information. DNA controls the growth and development of plants by providing instructions for processes such as cell division, photosynthesis, and the production of proteins essential for growth.

The information necessary to make the proteins that regulate cell growth and division is contained in what?
nucleus
What controls when and how fast cells grow and divide?
Cell growth and division are controlled by various factors, including signals from neighboring cells, internal signals within the cell, and external factors such as nutrient availability and growth factors. The cell cycle, which consists of stages like interphase and mitosis, regulates cell growth and division by coordinating the activities of proteins and enzymes that drive cell replication. Dysregulation of these controls can lead to diseases like cancer.
What does the nucleus do in a plant cell?
The nucleus in a plant cell houses the genetic material (DNA) that regulates cell activities and carries instructions for making proteins. It controls cell growth, division, and reproduction by directing the synthesis of proteins and coordinating cellular functions.
What do oncogenes normally encode for?
Oncogenes typically encode for proteins that promote cell growth and division. When these genes are mutated or overexpressed, they can drive uncontrolled cell growth, leading to the development of cancer.
When cells are not responding to normal controls over growth and division they form a tissue mass known as?
tumor
Most of the activities of a cell, including growth and division, are carried out by?
Most of the activities of a cell are carried out by proteins. Proteins serve as enzymes to catalyze chemical reactions, structural components to provide support, and signals to regulate cellular processes such as growth and division. Additionally, proteins play a critical role in transporting molecules and maintaining the cell's overall structure and function.
What are proteins that bind to cells and stimulate cell division are called?
Proteins that bind to cells and stimulate cell division are called growth factors. These proteins play a crucial role in regulating cell growth, proliferation, and differentiation by binding to specific receptors on the cell surface. Their signaling pathways can trigger various cellular responses, including cell division.
