What does EU and Karyote mean?
What does EU and Karyote mean?
Eukaryotic Cells “Eu” means “Well” and “Karyon” means “Nucleus” the name tells us that eukaryotic cells have a nucleus a WELL DEFINED NUCLEUS. The nucleus is well protected inside the nuclear membrane. They contain a true nucleus, consisting of nuclear membrane & nucleoli.
What is drug resistant eukaryotes?
Eukaryotic microbial pathogens can exhibit drug resistance through reducing the overall intracellular concentration of the drug (less uptake, more efflux), by inactivating or failing to activate the drug, or by sequestering the drug away from its target.
What does karyon mean in eukaryotic?
The term “karyotype” refers to the chromosomal pattern inside the nucleus of an animal cell (eukaryote), as well as to describes the set of chromosomes in a species or in an individual organism.
What do you mean by EU cell?
Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles. There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
What does the suffix Karyote mean?
a combining form meaning “nucleus of a cell,” used in the formation of compound words: karyotin. GOOSES.
What does karyon in prokaryote mean?
nucleus
The origin of the word prokaryote comes from the Greek “pro”, meaning before, and “karyon” which means nucleus or “kernel”. Prokaryotes lack a nucleus to store DNA. Their DNA is instead found in a circular form within the cytoplasm.
Why are eukaryotic cells not affected by antibiotics?
b. Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.
Why are eukaryotic cells unaffected by antibiotics in the tetracycline class?
Mechanism of action Tetracyclines can also inhibit protein synthesis in the host, but are less likely to reach the concentration required because eukaryotic cells do not have a tetracycline uptake mechanism.
What is an Idiogram?
Medical Definition of idiogram : a diagrammatic representation of a chromosome complement or karyotype.
What does the homologous mean?
having the same relative position
Definition of homologous 1a : having the same relative position, value, or structure: such as. (1) biology : exhibiting biological homology. (2) biology : having the same or allelic genes with genetic loci usually arranged in the same order homologous chromosomes.
What does EU mean in eukaryotic?
The word eukaryote comes from the Greek eu, “well,” and karyon, “nut or kernel,” which is a common scientific word-forming element that’s used to talk about the nuclei of cells.
What does suffix Bolic mean?
Answer and Explanation: The suffix -bolic means to throw up in words such as hyperbolic, anabolic, metabolic etc. It is derived from the Greek word ballein. Anabolic, which refers to the reactions which are used to build cells comes from Greek words which mean to throw up.
What does the prefix Prokary mean?
What does the prefix “prokary” mean? Before Nucleus. You just studied 20 terms!
What does EU and Kary mean in the word eukaryote?
The word part “eu-” means “true,” “pro-” means “before,” and “kary-” means “nucleus.” With this information, explain why the words “prokaryote” and “eukaryote” are good terms for the organisms they describe.
What is the meaning of Karyotic?
a combining form meaning “nucleus of a cell,” used in the formation of compound words: karyotin.
Can antibiotics be used on eukaryotes?
Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors.
What is the importance of the difference between prokaryotic and eukaryotic ribosomes with regard to antibiotic therapy?
2. Ribosomes – site of protein synthesis; prokaryotic ribosomes are smaller than eukaryotic ribosomes. Antibiotics such as tetracycline, erythromycin, and streptomycin can specifically target bacterial ribosomes & not harm the host’s eukaryotic ribosomes.
How does tetracycline affect eukaryotic cells?
The tetracyclines are believed to act by binding to ribosomes and impairing their ability to synthesize proteins necessary for growth and survival of a bacterium (51). They are generally believed to bind to the 30S ribosomal subunit, which is made up of a 1,540-nucleotide RNA (the 16S rRNA) and 21 proteins.
Why tetracycline has no effect on human cells?
They inhibit protein synthesis in both bacterial and human cells. Bacteria have a system that allows tetracyclines to be transported into the cell, whereas human cells do not; human cells therefore are spared the effects of tetracycline on protein synthesis.
What is ideogram in biology?
Ideograms are diagrammatic or idealized representations of chromosomes, showing their relative size, homologous groups and cytogenetic landmarks. Chromosomal analysis of cytological preparations involves calculation of karyotypic parameters and generation of ideograms.
What is eukaryotic cell diagram?
Eukaryotic Cell Diagram. Eukaryotic cell diagram mentioned below depicts different cell organelles present in eukaryotic cells. The nucleus, endoplasmic reticulum, cytoplasm, mitochondria, ribosomes, lysosomes are clearly mentioned in the diagram. Eukaryotic Cell Diagram illustrated above shows the presence of a true nucleus.
What are the functions of unicellular eukaryotic cells?
Unicellular eukaryotes perform many of the same actions as multicellular eukaryotes, such as locomotion, respiration, digestion, excretion, and reproduction. This picture depicts part of a eukaryotic cell with its enclosed nucleus and various organelles.
What are the organelles of a eukaryotic cell?
Eukaryotic cell: Structure and organelles 1 Plasma (cell) membrane. The plasma membrane is the outermost layer of the cell. 2 Cytoplasm. 3 Ribosomes. 4 Endoplasmic reticulum. 5 Golgi apparatus. 6 Vesicles and lysosomes. 7 Mitochondria. 8 Nuclear envelope. 9 Differences between animal and plant cells.
