Millions of cells residing within the marrow of your bones or the lining of your intestinal tract are undergoing division at this very moment. This enormous output of cells is needed to replace cells that have aged or died. Although cell division occurs in all organisms, it takes place very differently in prokaryotes and eukaryotes. We will restrict discussion to the eukaryotic version. Two distinct types of eukaryotic cell division will be discussed in this chapter. Mitosis leads to production of cells that are genetically identical to their parent, whereas meiosis leads to production of cells with half the genetic content of the parent. Mitosis serves as the basis for producing new cells, meiosis as the basis for producing new Fluorescence micrograph of a mitotic spindle that had assembled in a cell-free extract prepared from frog eggs, which are cells that lack a centrosome.

  • Cell Life Cycle and Reproduction the Cell Cycle (Cell-Division Cycle), Is a Series of Events That Take Place in a Cell Leading to Its Division and Duplication
    Cell Life Cycle and Reproduction The cell cycle (cell-division cycle), is a series of events that take place in a cell leading to its division and duplication. The main phases of the cell cycle are interphase, nuclear division, and cytokinesis. Cell division produces two daughter cells. In cells without a nucleus (prokaryotic), the cell cycle occurs via binary fission. Interphase Gap1(G1)- Cells increase in size. The G1checkpointcontrol mechanism ensures that everything is ready for DNA synthesis. Synthesis(S)- DNA replication occurs during this phase. DNA Replication The process in which DNA makes a duplicate copy of itself. Semiconservative Replication The process in which the DNA molecule uncoils and separates into two strands. Each original strand becomes a template on which a new strand is constructed, resulting in two DNA molecules identical to the original DNA molecule. Gap 2(G2)- The cell continues to grow. The G2checkpointcontrol mechanism ensures that everything is ready to enter the M (mitosis) phase and divide. Mitotic(M) refers to the division of the nucleus. Cell growth stops at this stage and cellular energy is focused on the orderly division into daughter cells. A checkpoint in the middle of mitosis (Metaphase Checkpoint) ensures that the cell is ready to complete cell division. The final event is cytokinesis, in which the cytoplasm divides and the single parent cell splits into two daughter cells. Reproduction Cellular reproduction is a process by which cells duplicate their contents and then divide to yield multiple cells with similar, if not duplicate, contents. Mitosis Mitosis- nuclear division resulting in the production of two somatic cells having the same genetic complement (genetically identical) as the original cell.

  • Deciphering Genetic Determinants of Cell Growth by Single-Cell RNA Sequencing Deregulated Growth Is a Hallmark of Human Diseases
    Deciphering genetic determinants of cell growth by single-cell RNA sequencing Deregulated growth is a hallmark of human diseases such as cancer. A wide range of therapeutic approaches target proliferating cells effectively through inhibition of pathways related to growth and division. However, cells can often escape arrest due to the genetic and phenotypic heterogeneity present in cancer cell populations leading to relapse of the disease. Likewise, heterogeneity in gene expression makes treatment of persistent microbial infections an important challenge for human health. Identifying genetic and non-genetic features that can drive individual cells to overcome growth inhibition is therefore required to understand disease progression and resistance. Recent experimental protocols made it possible to characterise the transcriptomes and genotypes of single cells simultaneously. These opened the door to investigate the dynamics and heterogeneity of gene expression in population of cells with variable genotypes. These methods are technically challenging, generate large amounts of complex data, and require the development of state-of-the-art computational methods for their analysis. Yet, when coupled with mathematical modelling of cell physiology, these single cells approaches have an unprecedented potential to unravel complex genetic and gene expression programmes that underlie growth dynamics of cell populations. This project aims at: i) understanding the genetic basis of cell growth under conditions were gene expression or proliferation are compromised by associating high fitness genotypes to transcriptome signatures in single cells, ii) develop computational tools to integrate single-cell and population level genotyping and gene expression data, iii) improve selected aspect of the laboratory single-cell RNA-seq protocol to improve data quality.

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of thebody’s tissues and organs. Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. The sequence of amino acids determineseach protein’s unique 3-dimensional structure and its specific function. Aminoacids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes. Proteins can be described according to their large range of functions in the body, listed inalphabetical order: Antibody. Antibodies bind to specific foreign particles, such as viruses and bacteria, to help protect the body. Example: Immunoglobulin G (IgG) (Figure 1) Enzyme.

  • Fishery Science – Biology & Ecology
    Fishery Science – Biology & Ecology How Fish Reproduce Illustration of a generic fish life cycle. Source: Zebrafish Information Server, University of South Carolina (http://zebra.sc.edu/smell/nitin/nitin.html) Reproduction is an essential component of life, and there are a diverse number of reproductive strategies in fishes throughout the world. In marine fishes, there are three basic reproductive strategies that can be used to classify fish. The most common reproductive strategy in marine ecosystems is oviparity. Approximately 90% of bony and 43% of cartilaginous fish are oviparous (See Types of Fish). In oviparous fish, females spawn eggs into the water column, which are then fertilized by males. For most oviparous fish, the eggs take less energy to produce so the females release large quantities of eggs. For example, a female Ocean Sunfish is able to produce 300 million eggs over a spawning cycle. The eggs that become fertilized in oviparous fish may spend long periods of time in the water column as larvae before settling out as juveniles. An advantage of oviparity is the number of eggs produced, because it is likely some of the offspring will survive. However, the offspring are at a disadvantage because they must go through a larval stage in which their location is directed by oceans currents. During the larval stage, the larvae act as primary consumers (See How Fish Eat) in the food web where they must not only obtain food but also avoid predation. Another disadvantage is that the larvae might not find suitable habitat when they settle out of the ~ Voices of the Bay ~ [email protected] ~ http://sanctuaries.noaa.gov/education/voicesofthebay.html ~ (Nov 2011) Fishery Science – Biology & Ecology water column.
