UVU offers master's, bachelor's, associate degrees, and certificates. [4] Previously called Utah Valley State College , the school attained university status in July 2008. With an enrollment of over 44,000 students as of fall 2023, UVU is the largest university by enrollment in Utah and one of the largest in the Rocky Mountain region of the ...
A heterokaryon is the melding of two or more cells into one and it may reproduce itself for several generations. [4] If two of the same type of cells fuse but their nuclei do not fuse, then the resulting cell is called a syncytium. [5] Heterotypic cell fusion occurs between cells of different types.
A laboratory method used in molecular biology to extract and isolate extrachromosomal DNA such as the DNA of plasmids (as opposed to genomic or chromosomal DNA) from certain cell types, commonly cultured bacterial cells. allele One of multiple alternative versions of an individual gene, each of which is a viable DNA sequence occupying a given ...
Prokaryotic cells divide by binary fission, while eukaryotic cells usually undergo a process of nuclear division, called mitosis, followed by division of the cell, called cytokinesis. A diploid cell may also undergo meiosis to produce haploid cells, usually four. Haploid cells serve as gametes in multicellular organisms, fusing to form new ...
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
When its size becomes too small, a dividing diatom cell produces an auxospore to expand its cell size back to that which is normal for vegetative cells. [ 2 ] Auxospores can also play a role in sexual reproduction in diatoms, and may be formed after haploid gametes fuse to form a diploid zygote .
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
In channels, they move down an electrochemical gradient to produce electrical signals. Pumps maintain electrochemical gradients. The main type of pump is the Na/K pump. It moves 3 sodium ions out of a cell and 2 potassium ions into a cell. The process converts one ATP molecule to adenosine diphosphate (ADP) and Phosphate.
