Random End Stuff Flashcards
DNA Mutations
deletion, duplication, insertion, inversion, translocation
Sex-Linked traits
associated with genes on the X chromosomes
sex-linked recessive traits are more common in males
Chromosome abnormalities
deletions, duplications, inversions, and translocations
nondisjunction and aneuploidy
extra or missing chromomes
Nirenberg and Khorana
described protein synthesis
deciphered genetic code
Choromosome 1
alzheimer’s, m.d., migraine, cataracts
Chromosome 2
colon cancer, parkinson’s, epilepsy, cataracts
chromosome 4
huntington’s
Replication
takes place during S phase
duplication of DNA
both strands of DNA Replicated (semi-conservative)
DNA polymerase
Transcription
RNA polymerase creates mRNA
Translation
mRNA exits the nucleus into the cytoplasm and goes through ribosomes/enzymes to be translated to proteins
