Chapter 12 Vocab Flashcards
Benign tumor
Mass of abnormal cells that remains at the site of it’s origin
Anaphase
The fourth stage of mitosis in which the chromatids of each chromosome have separated in the daughter chromosomes are moving to the poles of the cell
Binary fission
A method of asexual reproduction by division and have been prokaryotes binary fission does not involve mitosis put in Seguso eukaryotes there that undergo binary Fujian mitosis is part of the process
Cell cycle
An ordered sequence of events in the life of a cell, from its origin in the division of s parent cell until its own division into 2; the eukaryotic cell cycle is composed of interphase (including G1, S, and G2 sub phases) and M phase (including mitosis and cytokinesis)
Chromosomes
A cellular structure caring genetic material found in the nuclear sub eukaryotes cells each chromosome consists of one very long DNA molecule and associated proteins
Chromatin
The complex of DNA and proteins that makes up a eukaryotic chromosome when the cell is not dividing chromatin exist and it’s disbursed form as a master very long thin fibers that are not visible with the light microscope
Centromere
The specialist region of the chromosome were two sister chromatids are most closely attached
Cytokinesis
The division of the cytoplasm to form two separate daughter cells immediately after mitosis mitosis one or mitosis to
Centrosome
Structure present in the cytoplasm of animal cells important during cell division functions as a makers to be a orders and center syndrome has two centrioles
Cleavage
The process of cytokinesis in animal cells characterized by pinching of the plasma membrane
G1 phase
The first gap or growth phase of the cell cycle consisting of the portion of interface before DNA synthesis begins
G2 phase
The second app or growth phase of the cell cycle consisting of the portion of interphase after do you know synthesis occurs
Gametes
A haploid reproductive cells such as an egg or sperm gave me twos you know drink socially production to reduce the diploid zygote
G0 phase
A non-dividing stay occupied with so that I have left the cell cycle
Growth factor
A protein that must be present in the extracellular environment for the growth of normal development of certain types of cells a local regulator that XO nearby supposed to stimulate so roller for ration in differentiation
Interphase
The period in the soul cycle in the cell is not dividing during interfaceso you metabolic activity is high chromosomes and organelles are duplicated and so size may increase in her phase codes for 90% of the cell cycle
Mitosis
The process of nuclear division in eukaryotic cells conventionally divided into five stages pro fees prometaphase metaphase anaphase until the face mitosis conserves chromosome number by relocating replicated chromosomes equally to each of the daughter nuclei
Meiosis
A modified type of so the vision in situ reproducing organisms consisting of two rounds of cell division but only one round of DNA replication it resulted in souls with half the number of chromosomes as the original cell
Metaphase
The third stage of mitosis in which the spindle is complete in the chromosomes attached to microtubules at the Connecticut wars are all aligned at the metaphase plate
Metaphase plate
In imaginary plane midway between the two poles of the cell in metaphase on with those syndrome years of all duplicated chromosomes are located
Malignant tumor
A cancerous tumor that is invasive enough to impair the functions of one or more organs
Metastasis
The spread of cancer cells two locations distant from their original site
Cell plate
A double membrane cross the midline of the dividing played so between which the noon so I’ll forms during cytokinesis
Cyclin
I’m cellular protein that occurs in cyclical he flunks you waiting concentration and the plates and important role in regulating the cell cycle
