dna and protein synthesis Flashcards
rRNA does and where
makes up ribosome; manufactured in nucleolus
tRNA does and where
attaches to one amino acid and brings to ribosome
mRNA does and where
made in nucleus by transcription, carries directions to make proteins from nucleus/DNA to cytoplasm
replication
when ladder “splits in half” and complementary nucleotides fill in
transcription
how mRNA is made, ladder temporarily “unzips” and mRNA is made and leaves
translation
how proteins are made; mRNA codon gets read to make proteins
chromosomal mutation example
deletion, duplication, inversion, and translocation
gene mutation example
substitution, deletion and addition (frameshift)
mutagens
electromagnetic radiation and particulate radiation
Griffith and Avery
genetic inheritance and “transforming principle”
Hershey and Chase
virus (bacteriophages) and radioactive isotopes
Levene
discovered nucleotide and and ribose and deoxyribose
Chargaff
rules of base pairings a=t, c=g
Franklin and Wilkins
first/best x-ray model of double helix
Watson and Crick
created the DNA model
