Girls start to grow into women and boys into men. The changes happen due to the release of chemicals called hormones.

    Testosterone and oestrogen are responsible for the changes that occur in adolescence.

    DNA does not leave the nucleus. It is protected in the nucleus from damage. It is also too large.

    We copy small sections of DNA (a gene) to send out into the cell cytoplasm.
    This messenger then instructs the cell in which order to place the amino acids.

    We copy the DNA on to single stranded RNA. We call the messenger RNA mRNA.

    The mRNA moves to the ribosomes in the cytoplasm which helps the amino acids to join together in the correct order.

    The order of the bases in the mRNA strand determine what amino acids are needed and in which order.

    The finished protein then has a specific role in the cells, like receptors, enzymes, antibodies, or transport proteins like haemoglobin.

    Not all genes are copied and expressed in each cell. It depends on the role of the cell as to which genes are needed.

    We call this process protein synthesis]]>     2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576310     Task 1 gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576311 2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576311 Using PPQ gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576312 2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576312 PPQ gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576313 2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576313 MS gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576314 2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576314 The code - extra gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576315 The spec specifically says the details of transcription and translation are not needed but if you want to push your understanding you could watch the following videos in your own time

    There are different versions of the gene called alleles.

    For example, we all have a gene for eye colour. There is a version of that gene that gives blue eyes, another version gives brown. Blue and brown are the alleles]]>     2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576343     The code - Basic gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576344 The DNA code, the order of the base is a template for a protein.

    Proteins are made up of amino acids, the order of the amino acids give the protein its specific shape and structure.

    Every 3 bases on the DNA strand code for an amino acid. AAT, for example, will code for a different amino acids to ACT and TGT.

    The strand of DNA AATACTTGT would be the code for 3 different amino acids.

    Remember, some examples of proteins are enzymes and antibodies. The shape has to be complementary to its partners and even tiny changes will make it not fit.

It is estimated that the human body contains 30 trillion cells. How do we get from one to the other?

    Cell division.

    Cells need to be able to make more of themselves in order for use to grow and repair our bodies.

    The new cells must contain all of the same genetic information as the original. They must be genetically identical. 

    We have seen this type of cells division before in asexual reproduction and binary fission.]]>     2021-02-22 02:36:43 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576438     Meiosis gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1224576439 There are cells that we do not want to contain the exact genetic material as the original cell - gametes. Gametes contain half the number (haploid) of chromosomes as a normal body cell (diploid)

    When making gametes a similar process takes place, but the chromosomes are separated twice. the cells we end up with are genetically different to the original cell.

    We also have an extra stage when the chromosomes can swap some of their genes with each other. This means we mix up the combination of genes from both parent. This means the cells we get at the end of meiosis are genetically different to each other as well.

    Why is this important? This means each human that is born is unique and has a different combinations of alleles and characteristic. This give greater variation in the population. We will look at this in more detail next topic.

     - how I remember that mitosis happens in body cells but meiosis happens in the testes / ovary

    Mitosis produces an identical cell to the original. if a skin cell goes through mitosis, it makes new skin cells, if a muscle cell goes through mitosis it creates muscle cells.

    There are some cells which do not yet have a specific role or function. These are called STEM cells. We say they are unspecialised or undifferentiated.

  • There is variation within the population
  • Random mutations can occur that give an advantage
  • Organisms with the beneficial trait survive and breed
  • Alleles get passed on to the next generation
  • Organisms without the beneficial trait die
  • After generations, high % of the population have the beneficial allele

    • Keyterms: Natural selection, allele, gene, variation

Here the alleles and traits are not being chosen because it makes the organism better at surviving but because its is desirable to humans.

    The features required are identifies in an individual and they are crossed over several generations to ensure they are pure breed or homozygous for these alleles.

    This process reduces the genetic variation in the population.]]>     2021-03-11 07:14:52 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296736651     PPQ 1 gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737000 2021-03-11 07:15:00 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737000 PPQ 2 gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737352 2021-03-11 07:15:07 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737352 PPQ 3 gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737860 2021-03-11 07:15:14 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296737860 PPQ 4 gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738153 2021-03-11 07:15:21 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738153 PPQ 1 MS gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738463 2021-03-11 07:15:28 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738463 PPQ 2 MS gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738739 2021-03-11 07:15:34 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296738739 PPQ 3 MS gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296739050 2021-03-11 07:15:41 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296739050 PPQ 3 MS (2 marks version) gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296739427 2021-03-11 07:15:49 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296739427 PPQ 4 MS gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296742354 2021-03-11 07:16:45 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296742354 Adaptations gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296743206 2021-03-11 07:17:03 UTC https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296743206 Key vocab gerry_cheung https://padlet.com/gerry_cheung/4ykw2a15teyidkgm/wish/1296743584 Adaptive feature

This means each daughter cell is identical to each other, and the original cell.

    Plants can also reproduce from one parent, creating identical offspring. It is called Asexual reproduction.

    Advantages
    • You can create a whole new population from a single cell relatively quickly
    • Don't need to find second parent / sex cell (can be difficult if not a very motile organism)
    • If a plant is in a very isolated place, it is able to reproduce on its own
    • If a farmer has a perfect breed of crop, it can be easily copied and grown increasing yield or profit.


    Disadvantages
    • Lack of variation in the population, each member is a clone
    • Lack of genetic diversity means the population are vulnerable to disease, and changes in the conditions or environment
