Key Points from KT Flashcards
Mitochondrial Inheritance
only females can transfer the mt mutation to their offspring
heteroplasty often results in incomplete penetrance
mt disease are classified by type of mutations causing them
this has roles in DM, aging , and alziemhers
x linked recessive
from an unaffected carrier female to male
in these pedigrees we will see carrier females and affected males
x linked dominant
50% of sons affected, 50% of daughters affected
vertical tranmission
2:1 females to males affected
father to son transmission is NOT seen
HGP: Human Genome Project
a catalog of human genes
meiosis
dealing with gametes
you will see homolog exchange of material (which I s different between meiosis and mitosis)
1 diploid to 4 haploid gametes
mitosis
we have 1 diploid and we get 2 daughter cells
here we see no pairing of homologs and no exchange of material
this process takes roughly 1- 2 hours and the end result is that
DNA replication
happens during interphase
part of the central dogma
end goal is producing 2 identical copies of DNA
Transcription
this is when DNA becomes RNA
this involves a silencer, enhancer, coactivator
Translation
mRNA -> protein … Ribosomes perform and RNA brings AA for assembly
what are some factors the regulate gene expression
