      Correct. That is an active research topic for the cell biology of mitosis, meiosis, all of the special cases (such as asymmetrical cytokinesis) and all the ways it can go wrong (as in non-disjunction).

      @@janineleblanc-straceski3181 i love to talk to you more if possible about such a subject. i have no degree i cant afford college yet. I just a deep passion for helping Cancer patients that dose more good than bad some day. so the health of the motor molecules leans alot on the ATP for them to get around and Cancer has alot of factors one is it is a uncontrolled situation which is connected to the Mitochondria they activate caspase which helps with Apoptosis . so in short test the health of the motor molecules mainly the Kineasen and Dynien can be tested because the motility of the mitochondria is as far as my studies show done only by them. There is more i will see if i can chat with you more first

    There is an omission around 6:12. In the transition to the next slide I neglected to emphasize that the table contains data from the F2 generation - the offspring of the mating between the heterozygous female fly and the hemizygous male with all three recessive mutant alleles.

    If I have the length of a protein given as the numbers of aminoacids, can I say that the corrisponding mRNA has a minimum length of the number of the aminoacids times 3? Or does the UTRs also have a set minimum length?

    • @janineleblanc-straceski3181
      @janineleblanc-straceski3181 4 роки тому

      UTRs contain at the minimum the Kozak sequence for ribosome binding at the 5' end and the AAUAAA cleavage and polyadenylation site at the 3' end, and then the subsequent poly A tail (usually). I 'm not aware of any measurements of average or minimum length, but I'm sure there are some!

    Why doesn't the endonuklease cut just the tRNA out instead of cutting it with that extra bit of intron on it? Why the extra step with the exonuklease?

    • @janineleblanc-straceski3181
      @janineleblanc-straceski3181 4 роки тому

      The “why” question is a tricky one. There is seldom a satisfying answer. The short answer is that there is no good explanation that has been elucidated right now.

    why does the DNA only gets gut between histones? What prevents it from beeting cut at the curled around parts? Also Thank you for these awesome videos!

    • @janineleblanc-straceski3181
      @janineleblanc-straceski3181 4 роки тому

      That is a great question. As DNA is replicated - or transcribed - nucleosomes dissociate from the DNA and reform behind the polymerase. There's a lot going on at the replication fork and the transcription bubble!

    what are the protiens responsible for adding or putting the newly synthesized dna aroung histone is this occur at the same time when the new stard is just synthesized a histone protien in added?

    • @janineleblanc-straceski3181
      @janineleblanc-straceski3181 6 років тому

      That is a good question! There probably are some chaperone proteins. The newly synthesized DNA is immediately rewound around nucleosomes. Old nucleosomes are stripped off the template, broken down into half-nucleosomes that retain their epigenetic modifications (methylation, acetylation etc.) and mixed with brand new histones. Enzymes recognize the half- modified nucleosomes and duplicate the modifications on the new histones. (Re-call that a nucleosome core is an octamer of 2 each of H2A, H2B, H3 and H4.) That is how epigenetic modifications are passed from mother to daughter cells.
