A skin cell in a cat contains a total of 38 chromosomes. How many DNA molecules would therefore be found in the nucleus of the skin cell? What cell structure contains DNA? How many nucleotide bases does a codon consist of? What are the levels of DNA structure?
Where does mRNA synthesis take place in eukaryotic cells? Ribosome is composed of: A. RNA & DNA. B. DNA & protein. C. RNA & protein. D. RNA, DNA & protein. Does RNA editing occur in prokaryotes? Typically, how many replication origins are formed in: a. prokaryotes? b. eukaryotes?
Highly conserved protein dimerization domains that occur in many proteins involved in membrane dynamics and act as connecting links between actin dynamics and membrane rearrangements in all eukaryotes. BAR domains preferentially bind to curved membrane regions. Chromatin Complex of genomic DNA with proteins...
Thus these two types of ubiquitylation machines have evolved to carry out distinct functions in the regulation of cell growth. A final point to be made from Table 1 is the broad range of species represented. Indeed, it is fair to say that probably all eukaryotes use Ub- mediated proteolysis...
Sex chromosomes have evolved independently many times throughout the eukaryotes, and represent a remarkable case of genomic convergence, as unrelated sex chromosomes share many properties across distant taxa1–3. Sex chromosomes evolve after recombination is halted between a homologous pair of chromosomes...
Many mitochondrial and plastid proteins are derived from their bacterial endosymbiotic ancestors, but their genes now reside on nuclear chromosomes instead... JL Blanchard,M Lynch - 《Trends in Genetics》 被引量: 284发表: 2000年 Multiple promoters are a common feature of mitochondrial genes in Arab...
[16,17] and the realisation that it may be adapted to create an artificial drive mechanism in eukaryotes analogous to HEGs (zinc-finger nucleases and TALENs might similarly be employed) [3,18] has brought many new laboratories into the field (see also Additional file1: Note 1). At the ...
TOPIC: CELLS AIM: HOW DO CELLS WORK? Hw: Have a great weekend!!! ;-)! If there are so many cells how do we classify them? 2.Based on the type of organism it belongs to Plant cell Animal cell 1.Based on location or function of the cell blood cell muscle cell ...
The discovery of RNA interference phenomenon (RNAi) and understanding of its mechanisms has revolutionized our views on many molecular processes in the living cell. Among the other, RNAi is involved in silencing of transposable elements and in inhibition
Why does synapsis occur in meiosis and not mitosis? How do chromosomes in eukaryotes separate during binary fission without centrosomes? If a homologous pair of chromosomes fails to separate during meiosis I, what will be the result? How are the products of meiosis and the products of mit...
