    the conclution is even mutation will happen ( cut enzyme that NC can not produce protein cause mutation ) . so i choose , protein synthesis cause ariginin is protein but when i understand deeply . Splicing gen cause mutation and it can deactivation enzym produce each ornitin or ariginin .Sorry iam wrong.

    Just for clarification: the BPA diet study on the mouse model, it doesn’t necessarily conclude if low methylation/high methylation is good/bad, right? The main conclusion is that, we see BPA diet can affect the methylation in mouse gene expression of the yellow fur coat gene - which means is just one example of how gene expression can be affected by something like BPA. Would that be correct ?

    • @SciEdSusan
      @SciEdSusan 2 месяца назад

      You are correct: this experiment tells us only that the diet and environment are able to influence genome methylation. The inference would be, the abundance of manmade chemicals and preservatives in our modern world might be having unpredicted (and unpredictable) effects on our genes and thus our health and development...and that of future generations.

    • @emmabuckland1361
      @emmabuckland1361 2 месяца назад

      I think it's because it is happening during the development of the mouse, not necessarily after the mouse has developed and grown.

    why is it important to use haploid spores and not diploid of neurospora crassa in this experiement?

    • @SciEdSusan
      @SciEdSusan Год назад

      It's easier to make haploid mutants than diploid ones - you would only need the mutation in one copy (the only copy) of the gene.

From that youtube video, I can get a list of materials I will need. Where can I get the materials I need, plus the other knowledge necessary? I already have a blender.

    I don't understand where 0.52 and 0.08 come from. Would you not take the square root to solve for p and q?

    • @SciEdSusan
      @SciEdSusan 2 года назад

      0.52 and 0.08 are the expected homozygous genotype frequencies for RR and rr, given the current allele frequencies p & q. We calculate p-squared (freq of RR) by squaring p (allele freq of R) and q-squared (predicted freq of rr individuals) by squaring q (allele freq of r).

    • @SciEdSusan
      @SciEdSusan 2 года назад

      ​@@RuJoe720 There are a couple of questions we can ask using the HWE ideas. A common one is, if you know how many white (homozygous recessive rr) individuals there are in a population, then figure out p & q (the allele frequencies of R & r). In that case, usually you DO just take the square root of rr to get q! Here, we’re asking, given all three genotype frequencies, can we figure out if the population is in HWE? So first we calculate p & q, and since we are NOT assuming this pop is in HWE, we include the heterozygotes in the calculation. (We’re not assuming HWE bc we’re trying to test for HWE!) Then, once you have p & q, now you can calculate the expected or predicted values for each genotype, and compare them with what we already have observed in our population, to see if expected = observed. Hope this helps!

    Very nice explanation maam. I have a question that is, I am taking total reaction volume of 250 ul. So while calculating, do i have to convert the value in ml that is.25ml (for example you have taken 1.5ml*1l/1000ml).likewise I have calculate in this manner. 25ml*1l/1000ml, so that ml gets cancel out and left out with mol unit.

    • @SciEdSusan

      That’s right! You need to cross-cancel to get to moles.
