PROTEIN SYNTHESIS Chapter 10
2
DNA RNA NUCLEIC ACIDS Store information FUNCTION
________________________: Store information
3
NUCLEIC ACIDS Made up of NUCLEOTIDE subunits NITROGEN BASE
4
5 NITROGEN BASES Adenine A=_____________ T= _____________
C= _____________ U= _____________ Thymine Guanine Cytosine Uracil
5
RNA RIBOSE SUGAR = _________________
NITROGEN BASES = _________________ A, U, C, G
6
RNA _____________ and _________ form the chain _________________
SINGLE STRANDED U _____________ and _________ form the chain PHOSPHATES SUGARS _________________ stick out to side NITROGEN BASES
7
DNA DEOXYRIBOSE SUGAR = _________________
NITROGEN BASES = _________________ A, T, C, G
8
DNA _____________ and _________ make the sides of the ladder
DOUBLE STRANDED _____________ and _________ make the sides of the ladder PHOSPHATES SUGARS NITROGEN BASES _________________ make the steps
9
“Twisted ladder” called a DOUBLE HELIX
DNA “Twisted ladder” called a DOUBLE HELIX
10
BONDING RULES HYDROGEN T A G C
_______________BONDS hold two strands together ____ always bonds with ____ HYDROGEN T A G C
11
DNA RNA Double stranded Single stranded Deoxyribose sugar Ribose sugar
A, T, G, C A, U, G, C No Uracil No Thymine Stays in nucleus Made in nucleus but moves to cytoplasm Makes up Carries genetic code genetic code to ribosomes and changes code into a protein
12
CELL DNA is found in nucleus RIBOSOMES are found in cytoplasm

WAY INFORMATION IN PASSED IN CELLS _____ _________________ DNA RNA PROTEIN
14
WAY INFORMATION IN PASSED IN CELLS
DNA = REPLICATION
15
DNA can copy itself = __________________
REPLICATION Happens during ______________ CELL DIVISION (S)
16
REPLICATION DNA unzips DNA POLYMERASE proteins
move along strands and use code to make 2 new matching DNA strands REPLICATION LINK
17
WAY INFORMATION IN PASSED IN CELLS
_____ _____ RNA DNA = TRANSCRIPTION
18
TRANSCRIPTION DNA unzips RNA POLYMERASE protein
moves along strand and uses code to make an RNA strand RNA strand leaves nucleus and travels to ribosomes in cytoplasm DNA zips back together TRANSCRIPTION LINK
19
TRANSCRIPTION MAKES 3 KINDS of RNA TO DO DIFFERENT JOBS
RIBOSOMAL-RNA ________________________ (r-RNA) makes up the ribosomes ________________________ (m-RNA) carries DNA code out to ribosomes _______________________ (t-RNA) matches the m-RNA to add the correct amino acids to the protein chain MESSENGER-RNA TRANSFER-RNA
20
Ribosomal-RNA (r-RNA)
Made in NUCLEOLUS; joins with proteins to make ribosomes
21
Messenger-RNA (m-RNA)
Carries message from DNA in nucleus to ribosomes in cytoplasm
22
Transfer-RNA (t-RNA) “hairpin” shaped RNA
AMINO ACID BINDS HERE “hairpin” shaped RNA Binds m-RNA at one end and a specific amino acid at other end m-RNA BINDS HERE Image from:
23
ANTICODON CAU M-RNA G U A C A C G G C U U A AMINO ACID BINDS HERE

24
WAY INFORMATION IN PASSED IN CELLS
_________________ RNA PROTEIN = TRANSLATION
25
PROTEINS ARE MADE OF AMINO ACIDS
26
20 AMINO ACIDS are used by all cells to make proteins
R group is different in each Modified from:
27
TRANSLATION M-RNA attaches to ribosome
As ribosome moves along m-RNA strand, t-RNA anticodons match the code and bring in the correct amino Enzymes join the amino acids and t-RNA drops off When the end is reached, ribosome and protein separate (Ribosome, m-RNA, and t-RNA can then be reused to make another protein)
28
_____________on t-RNA matches the ________ on the m-RNA and adds the correct amino acid ANTICODON CODON
29
UUU – Phenylalanine GUC -Valine AUG = Start codon
Images Modified from:
30
TRANSLATION TRANSLATION LINK
31
PROTEIN STRUCTURE AMINO and CARBOXY groups join to make a chain when WATER is removed
