exam 3 pt.2
Termini in questo insieme (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.
