• chromosomes
  • Prokaryotic DNA is circular and is neither associated with histones nor organized into chromosomes. (news-medical.net)
  • This involves numerous stages - the nuclear membrane disintegrates then the chromosomes are sorted and separated to ensure that each daughter cell receives two sets (a diploid number) of chromosomes. (news-medical.net)
  • The genome is composed of a number of chromosomes-complexes of tightly coiled DNA that contain genetic information vital for proper cell function. (wikipedia.org)
  • Microtubules project from opposite ends of the cell, attach to the centromeres, and align the chromosomes centrally within the cell. (wikipedia.org)
  • As the cell elongates, corresponding daughter chromosomes are pulled toward opposite ends of the cell and condense maximally in late anaphase. (wikipedia.org)
  • protein
  • however, whereas peptidoglycan helps maintain the structural strength of the cell, it is actually the MreB protein that facilitates cell shape. (wikipedia.org)
  • Gram-positive cell wall Penicillin binding protein forming cross-links in newly formed bacterial cell wall. (wikipedia.org)
  • In eukaryotic cells, K+ channels are involved in neural signalling and generation of the cardiac rhythm, act as effectors in signal transduction pathways involving G protein-coupled receptors (GPCRs) and may have a role in target cell lysis by cytotoxic T-lymphocytes. (wikipedia.org)
  • nucleoid
  • The materials are already fairly close to each other and there is only a 'nucleoid' which is the central open region of the cell where the DNA is located. (news-medical.net)
  • distinct
  • This record, obtained from the West Antarctic Ice Sheet (WAIS) Divide (WD) ice core, spanned from the Last Glacial Maximum (LGM) to the early Holocene (EH) and showed distinct fluctuations in prokaryotic cell concentration coincident with major climatic states. (readbyqxmd.com)
  • Cell type - Distinct morphological or functional form of cell. (wikipedia.org)
  • There are at least several hundred distinct cell types in the adult human body. (wikipedia.org)
  • typically
  • Previously, this procedure involved preparing a blood cell stain and manually counting each type of cell under a microscope, a process that typically took a half-hour. (wikipedia.org)
  • Typically tubular, multinucleated, and with a chitinous cell wall. (wikipedia.org)
  • During mitotic progression, typically after the anaphase onset, the cell may undergo cytokinesis. (wikipedia.org)
  • species
  • Transformation is a common mode of DNA transfer, and 67 prokaryotic species are thus far known to be naturally competent for transformation. (wikipedia.org)
  • Although mRNAs possess great diversity, they are not the most abundant RNA species made in the cell. (wikipedia.org)
  • metabolic
  • One is to establish physical boundaries for biological processes that enables the cell to carry out different metabolic activities at the same time. (wikipedia.org)
  • Cellular respiration - The metabolic reactions and processes that take place in a cell or across the cell membrane to convert biochemical energy from fuel molecules into adenosine triphosphate (ATP) and then release the cell's waste products. (wikipedia.org)
  • divides
  • This is an asexual method of reproduction in which a 'parental' cell divides into two smaller but equally sized cells. (weebly.com)
  • progeny
  • This genetic material needed to regulate cell function and encodes the information which is passed onto progeny. (news-medical.net)
  • In relation to this, the mutation of stem cells or their progeny may give rise to cancer stem cells. (coursehero.com)
  • molecule
  • Following "sticky end" ligation of the insert into the vector the resulting recombinant DNA molecule is transferred into E. coli host cell for cloning. (wikipedia.org)
  • If the molecule is enclosed in a cell membrane, then the enzymes coded will be available only to the replicator molecule itself. (wikipedia.org)
  • cellular
  • It contains the DNA-related functions of the large cell in a smaller enclosure to ensure close proximity of materials and increased efficiency for cellular communication and functions. (news-medical.net)
  • Due to the larger size of the eukaryotic cells, confining certain cellular process to a smaller area also increases the efficiency of functions by improving communication and movement within the cell. (news-medical.net)
  • When a cell switches state from one cell type to another, it undergoes cellular differentiation. (wikipedia.org)
  • organism
  • It is the smallest unit of an organism that is classified as living, and also known as the building block of life.Etymology of "cell" - Comes from the Latin cellula, meaning, a small room. (wikipedia.org)
  • Vital functions of an organism occur within cells. (wikipedia.org)
  • Tissues - A collection of interconnected cells that perform a similar function within an organism. (wikipedia.org)
