Have your lab reports out and ready to turn in
Answer the following questions: Where does replication happen? What is the purpose of replication? What are three organelles in the cell and
what are their functions? What are the products and reactants of
photosynthesis?
DNA Replication-1 DNA to 2 DNA (happens in nucleus).
Transcription-DNA to mRNA (in nucleus)
The scientific belief that DNA is converted to RNA to produce proteins through the processes of transcription and translation
The order of DNA affects the order of RNA which affects the order of Protein
Translation is the process of turning mRNA into an amino acid chain which can fold up to become a protein.
Building blocks of proteins
20 different types Different
combinations and orders of amino acids produce different proteins
-mRNA molecules leave the nucleus and attach to ribosomes.
-tRNA molecules bring amino acids to the ribosome and then the tRNA molecules match up with codons on the mRNA and form amino acid chains.
-The end result of translation are amino acid chains which fold up to become proteins.
THECATATETHEHAT
Sequence of 3 nitrogen bases
THE CAT ATE THE HAT
A three letter sequence of mRNA that matches a tRNA-protein
The three letter complementary base pair on tRNA that complements mRNA
-Translation happens on the ribosomes attached to the Rough E.R.
Translation-mRNA to amino acid (A.A.) chain which becomes a protein (on ribosomes in cytoplasm.
What happens in translation?-the mRNA is turned into an amino acid chain which folds up to become a protein.
Which of these processes does NOT use DNA?
a. DNA Replication b. Transcription c. Translation
Answer-Translation (from mRNA to protein)
Is mRNA made in transcription or translation?
-transcription
Is tRNA used in transcription or translation? -translation
