1/20
  • Theory of pangenes


    cells let out particles that are inherited (WRONG)

  • Blending hypothesis


    traits are blended together ( WRONG)

  • law of segregation on a chromosomal level


    chromosomes are separated then randomly paired up during metaphase

  • Process of DNA replication


    • Helicase unzips

    • Primase adds RNA primer

    • Dna polymerase adds DNA nucleotides

  • Location, reactant, and products. of transcription


    • In the nucleus

    • DNA

    • mRNA

  • translation


    in the cytoplasm

    mRna

    Protein

  • How is RNA processed?


    5' cap added, poly a tail added, introns removed, extrons kept

  • selective gene expression


    knows what it needs and what it doesnt

  • alternative dna splicing


    allows one gene to code for multiple proteins. leaves certain introns alone

  • Risks of GMOS and safeguards


    disrupt the environment around it

    infecting non target crops

    strict government testing, physical barriers, etc

  • plasmid


    single circular double stranded DNA molecule

  • recombinant DNA


    lab created molecule made by combining dna of two different organisms

  • restriction site


    specific dna sequence bound by a restriction enzyme

  • transgenic organism


    gene edited by insertion of material from another species

  • vector


    organisms used for carrying disease or viruses

  • reverse transcriptase


    converts RNA to DNA

  • Concept of epigenetic inheritance


    The transmission of traits to offspring my methyl tags. the genetic doe itself is not changing. these are caused by environmental factors.

    ex. identical twins are born with the same DNA but one may develop a disease while the other doesn't because of their environment.

  • Describe the structure of DNA using key words,


    DNA is a double helix twisted ladder made of a 5 carbon sugar, phosphate group- Po4- and nitrogenous bases - ATGC

  • Important scientists and the experiments


    • Discovered transformation factor (genes)

    Watson and Crick

    • Made a cardboard model of DNA, used Rosalinds findings to solidify the idea that Dna is a double helix

  • CRISPR-Cas9 System – technique, possible treatments and applications, ethical consideration with germline editing


    gened editing tool

    • can treat diseases by modifying cells

    • could be used for enhancement and kids aren't able to give consent to this. unexpected consequences can also happen.
