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
