    Don't you just love it when a less than 10min video teaches you what your teacher hasn't managed to teach you for a WHOLE SEMESTER :)) I am lowkey so mad right now, this whole thing about translating mRNA stressed me tf out for MONTHS, giving me so much anxiety and now you're telling me that all it took was just ignoring my teacher and watching a youtube video?? :))

      You get very easily from Khan sir ac.
      Coz u come here after a struggle in understanding the topic and during the struggle u unconsciously get some idea about the topic and when u watch video ur brain learns fast ⏩

    UNIVERSALITY OF THE CODE - Initially the genetic code was believed to apply universally, that is all organisms would recognize individual codons as the same amino acids. However, it has now been shown that some variation in the code exists, although this is rare. For example, animal mitochondria have a small DNA genome containing about 20 genes in which deviations from the genetic code occur. Changes are mostly associated with start and stop codons. For example, UGA, which is normally a termination codon, codes for tryptophan, whereas AGA and AGG, which normally encode arginine, are termination codons, and AUA, normally isoleucine, specifi es methionine. It is thought that these changes tend to be viable because the mitochondrion is a closed system. A few examples of nonstandard codon usage have now been found outside mitochondrial genomes in unicellular organisms. For example UAA and UAG, which are normally stop codons, encode glutamic acid in some protozoa.

    How were the codons assigned to their amino acids? It's my understanding that the order of the nucleotides doesn't release an enzyme or anything that could possibly link codons with their specific amino acid. So how is the code being "read"?

    • @werkatfischer3183
      @werkatfischer3183 2 года назад +1

      Noncoding DNA can actually still play a big part in gene regulation since the length of LINEs/SINEs/STRs can affect the rate at which coding regions are transcribed, as well as affecting the structure of chromatin and where genes are activated.

    That was very helpful. I understood that well. Now I know the base to start at. But my question is “ explain that variations in trait are caused by variations in the genetic code” I feel like I understand that, but is there another video y’all recommend to further learn?

    • @newfie-dean5803
      @newfie-dean5803 5 лет назад +4

      Carly Fisher the DNA is made up of many genes all of varying lengths. Some genes might have a sequence that contains 150 nucleotides in length. Other genes might have 1 million nucleotides in the sequence. It is the variation of nucleotide sequencing within a given gene that results in different traits. Here’s a simplified example. Maybe you have ACGTAC as a sequence in a hair gene that gives a person brown hair but in another hair gene you have ATGCAC which gives the person black hair. What genes you have to begin with are determined by what was passed to you from your parents.

    Why are Chromosomes almost always showen in the distinct X shape, which is only shaped like that after duplication. i mean most of the time Chromosomes are just lines with a centromere. when you depict it as an X shape you confuse students who need to know and sketch meiosis and mitosis.

    • @amnawajahat6418

      nevermind, it only works for U and C in the second letter of genetic code

    • @MelatWorku
      @MelatWorku 6 лет назад +1

      it does make a difference if you go from Purine (Either A or G) to a a pyrimidine (T(u) or C) and vice versa. The reason has to do with the number of rings associated with the bases. If you go from a purine to purine or pyridine to pyrimidine, you don't see a difference in the amino acid. So going from U to C, does not affect it as you're going from a pyrimidine to a pyrimidine and the same thing applies to going from A to G.
