Which pair of nitrogenous bases are correctly matched?
Adenine with cytosine Adenine with thymine Cytosine with thymine Guanine with Adenine What is the complimentary DNA strand for a gene with the sequence GAC TTA AGA GGC AGA TGC GAC GGC TTA AGA TGC CCA CUG AAU UCU CCG UCU ACG CTG AAT TCT CCG TCT ACG GAC ATU CGA GGU TCT CCA
2
Which statement is true concerning the light- dependent and light-independent reactions of photosynthesis? Water is required for the light-dependent reactions, and carbon dioxide is required for the light-independent reactions Glucose is required for the light-dependent reactions, and oxygen is required for the light independent reaction Oxygen is required for the light independent reaction, and glucose is required for the light independent reactions Carbon dioxide is required for the light dependent reactions and water is required for the light independent reactions

Central Dogma theory DR pepper time
4
DRPT will transcribe, translate, express
What time is it? DR Pepper Time DRPT will transcribe, translate, express DNA is transcribed to RNA RNA is translated to proteins Proteins are expressed as Traits
5
DNA Super-base “Let’s see if you learned the words.”
6
DNA Replication Review
Two strands of DNA unwind and unzip Free floating nucleotides are paired with each strand and form hydrogen bonds Sugar phosphate bonds to create backbone
7
Let’s Practice: Give the complimentary Strand
GCG ATA CTA CGA TTC AGG GGA TAT __ __ __ __ __ __ Complete the DNA compliments on Examples 1-4 on the worksheet.
8
DNA & RNA Comparison RNA single strand ribose uracil DNA double strand deoxyribose thymine
9
RNA: ribonucleic acid A single strand of nucleotides; three different types are used to translate instructions from DNA into making Proteins Messenger RNA (mRNA): carries the code from DNA in the nucleus to the cytoplasm Transfer RNA (tRNA): carries an amino acid and transfers it ti the protein chain being assembled at the ribosome Ribosomal RNA (rRNA): reads the codons from messenger RNA,

Central Dogma
13
Transcription The process occurring in the nucleus of the cell that copies the instructions from a part of DNA onto a strand of messenger RNA (mRNA)
14
Steps of Transcription
DNA unzips RNA nucleotides pair with open DNA nucleotides mRNA (messenger RNA) is formed mRNA leaves the nucleus through holes in the nuclear membrane
15
Transcription DNA RNA Nucleus
16
Let’s Practice: Complimentary mrna
DNA Sequence GCG ATA CTA CGA TCT AGA ATT GAC mRNA __ __ __ __ __ __ Complete the mRNA compliments on Examples 1-4 on the worksheet.
17
tRANSLATION The process occurring in the cytoplasm of a cell that builds proteins. The rRNA attaches to the mRNA and begins to “read” the sequence (codon) 3 base pairs at a time. tRNA is then used to carry the amino acids to the ribosome.
18
Translation RNAProtein Occurs at the Ribosome in the Cytoplasm
19
Translation mRNA enters the Ribosome
The Ribosome closes the large and small sub-unit The Ribosome reads the code 3 bases at a time Codon
20
Translation tRNA (transfer RNA) Brings Amino Acids to the ribosome to make a protein
21
Translation The anti-codon (3 bases) on tRNA matches with the codon (3 bases) on mRNA
22
Complete the tRNA compliments on Examples 1-4 on the worksheet.
Let’s Practice mRNA Sequence UUC CCU CUA CGA GCU AAG AUU GAC tRNA Sequence __ __ __ __ __ __ Complete the tRNA compliments on Examples 1-4 on the worksheet.
23
Translation The amino acids stick together with a peptide bond The protein is released and folds into the correct shape rRNA=ribosomal RNA
24
Reading Codon Charts: Hall, Room, Seat
25
Complete the amino acid sequence on Examples 1-4 on the worksheet.
Let’s Practice mRNA AUU AAA GCU CCC CUA CAU AAC GGC ACU UCG Amino Acids ____________ ____________ Complete the amino acid sequence on Examples 1-4 on the worksheet.
