Most differentiated cells retain?
A complete set of their genes, and retain the ability to express those genes under certain circumstances.
Why only certain cells produce certain products?
Control genes impede certain genes from expressing themselves and allow others to express themselves/ Thus a liver cell will have basically the same genome as a neuron, but will not express axon development and the neuron will not express bile development.
How are cells in single cells and multicellular organisms similar?
Cells that are part of a multi-cellular organism typically have the same metabolic functions as single-celled organisms, however differences exist. Multicellular cells will have a specialized function, typically do not have to independently gather food and will express target genes selectively rather than all of the genes necessary for survival that a single-celled organism might express.
Do eukaryotic cells have genes?
All cells have genes
Do all body cells activate the same genes?
All body cells have the same genes except for the sex cells (sperm and ova). They do not use the same genes. A muscle cell isn't using the same genes as a nerve cell does. Otherwise the muscle cell and the nerve cell would not be different nor do different things.
How do genes affect cells?
Genes tell cells how to make proteins.
What does differential gene expression mean?
The process by which different cells express different genes depending on their needs is called differential gene expression
Which genes are present in your liver cells?
All your genes are present in your liver cells
What is the difference between Cells and Genes?
The Cells hold the genes. Genes are a part of DNA, which is located in the Nucleus of a Cell.
Which cells are influenced by natural selection?
In one way or another, all of them. However, we generally don't speak of natural selection in terms of how it affects cells (except perhaps germline cells), but in terms of how it affects populations, lineages or allele frequencies in gene pools. In population genetics, cells are merely the containers for collections of genes, and the machines that express those genes.
What cells build bone tissue?
In bone, there are osteoblasts (cells which build bone) and osteoclasts (cells which break down bone). In the bone marrow and spongy bone, there are hematopoietic cells (cells which make blood). Bone is a type of connective tissue that is made of specialized cells that all work together for a common function. Their cellular and extracellular matrix is what makes bone cells so unique.
What are Osteoblasts and Osteoclasts?
Osteoblasts are one type of bone cell (out of three) that is found in bone tissue. They are bone forming cells (make bone) (bone builders). It deposits bone even as another bone cell, osteoclasts, breaks it down. When there is a break, or lacuna, in the bone the osteoblasts form a sheet over the gap. Then osteoids cover the osteoblats trapping them in the lacuna. Inside the lacuna they then turn into osteocytes, a type of bone cell.osteoblasts are bone forming cells, and osteoclasts are bone destroying cells.Osteoblasts (from the Greek words for "bone" and "germ" or embryonic) are mononucleate cells that are responsible for bone formation; in essence, osteoblasts are sophisticated fibroblasts that express all genes that fibroblasts express, with the addition of the genes for bone sialoprotein and osteocalcin.[1]Osteoblasts produce osteoid, which is composed mainly of Type I collagen. Osteoblasts are also responsible for mineralization of the osteoid matrix. Zinc, copper and sodium are some of the many minerals produced. Bone is a dynamic tissue that is constantly being reshaped by osteoblasts, which build bone, and osteoclasts, which resorb bone. Osteoblast cells tend to decrease as individuals become elderly, thus decreasing the natural renovation of the bone tissue.[2]osteoblasts produce bones in the body. they are bone producing cellsAn osteoblast is an immature bone cell. Eventually, the osteoblast will mature into an osteocyte and ossify, or harden, into bone.Living cells within the bone are engaged in an unceasing process of remodeling. Osteoblasts lining the surface of bone are much like fibroblasts and deposit and organize new bone matrix while osteoclasts demolish old bone matrix. Osteoblasts are converted into osteocytes as they become embedded in this matrix and the matrix calcifies.
