BIO EXAM 2 Flashcards
HELICASES
UNDWINDS DNA
SPBP
DNA TRANSCRIPTION
HOLDS DNA TOGETHER
TOPOISOMERE
DNA TRANSCRIPTION
Relieves tension generated by the unwinding of the double helix dna strand
DNA POLYMERASE 1
DNA TRANSCRIPTION/ REMOVES PRIMER
DONA POLYMERASE 2
DNA TRANSCRIPTION/ ADD 3 NEW NUCLEOTIDES
LIGASE
REPLICATION/ JOINS FRAGEMENTS OF NEWLY SYNTHESIZED DNA TO FORM A NEW SEAMLESS STRAND
RNA POLYMERASE 2
TRANSCRIBES POLYPEPTIDE CODING GENES INTO MRNA
WHAT does rna splicing not happen at
at the chromosomes levels
trna
translation brings amino acid and places them in the correct place to create protein
mrna
transcription
carries genetic information to the rest of the cells
Rrna
protein synthesis/ stitches amino acid together to make proteins
Aminoacyl-tRNA synthetase
PAIRS Trna with their cognate amino acid
activators
dna transcription/ a protein that binds to dna and stimulates transcription of gene expression
repressors
transcriptions/ turns off or redces gene expression
transcription factors
converst rna into dna
