PRESENTATION OUTLINE
DNA FROM GENES ON CHROMOSOMES RUN RNA PROCESSING
rRNA CONTROLS PROTEIN SYNTHESIS
PROTEIN SYNTHESIS STARTS WITH TRANSCRIPTION
RIBOSE SUGAR IS THE BUILDING BLOCK OF RNA
DNA CHANGES TO A SINGLE STRAND AND IS NOW A TRANSCRIPTION UNIT
RNA POLYMERASE IS AN ENZYME WHICH PERFORMS TRANSCRIPTION
TRANSCRIPTION FACTORS ATTACH TO PROMOTERS
DNA STRANDS ARE PULLED APART
DNA WINDS AROUND HISTONE PROTEINS
RNA POLYMERASE PAIRS UP NUCLEOTIDES AND COMPLEMENTS
THE TEMPLATE STRAND IS USED FOR RNA SYNTHESIS
THE CODING STRAND IS USED TO SIGNAL THE TATA BOX
POLYMERASE CODES FOR CODONS
POLYMERASE MOVES FROM 3' TO 5' ADDING NUCLEOTIDES
URACIL PAIRS WITH ADENINE
THYMINE, GUANINE AND CYTOSINE ARE ALSO N- BASES
RNA PROCESSING HAPPENS BEFORE TRANSCRIPT IN EUKARYOTIC CELLS
PRIMARY TRANSCRIPT DOES NOT CODE FOR A POLYPEPTIDE
A CODING SEGMENT IS A POLYPEPTIDE WITH A START CODON AND A STOP CODON
A CAP OF GUANINE IS ADDED TO THE 5' END
THE 3' END HAS A POLYA TAIL OF ADENINE
SPLICEOSOMES FORM MORE PROTEIN STRUCTURES
RNA LEAVE THE NUCLEUS AND ENTERS THE CYTOPLASM
PROTEIN IS TRANSLATED FROM RNA
TRANSLATION FORMS A POLYPEPTIDE CHAIN
MRNA GOES THROUGH A RIBOSOME
AMINO ACIDS MAKE UP POLYPEPTIDES
TRANSFER RNA PAIRS BASES WITH AMINO ACIDS
INITIATION, ELONGATION, AND TERMINATION TAKE PLACE
AN ANTICODON BONDS TO THE START CODON AUG
METHIONINE IS GIVEN BY TRNA
AN INITIATION COMPLEX IS FORMED
CODINS PAIR WITH ANTICODONS TO LENGTHEN THE POLYPEPTIDE
THE PEPTIDE BOND IS CATALYZED
STOP CODONS END TRANSLATION
RELEASE FACTORS BIND STOP CODONS
POLYPEPTIDES ARE ALTERED WITH OTHERS TO FORM A NEW PROTEIN
