Transcription

1 The actual process of assembling the proteins on the ribosome is called? translation The building blocks of proteins are? Complementary base pairing links Define and name the Purines amino acids nitrogen containing bases like A, G, T, C, and U Nitrogen bases with two rings of carbon like Adenine and Guanine Define and name the Pyrimidines During replication, the two strands of DNA separate at a point called a? Nitrogen bases with one ring of carbon like Thymine, Cytosine, and Uracil replication fork During translation, one end of a trna molecule pairs with a complementary? Groups of three mrna nucleotide bases are called? Groups of three trna nucleotide bases are called? How do proteins differ from person to person? mrna codon codons anti-codons The amino acid sequence

2 How does DNA differ from person to person? How many amino acids do most human proteins consist of? The nucleotide sequence several hundred How many different amino acids are there? In the Identify the Protein lab, what did the numbered strip represent in a real cell? 20 DNA sequence In the Identify the Protein lab, what was each letter on the strip supposed to represent in a real cell? The protein that is responsible for carrying oxygen to all of your tissues the nucleotide sequence hemoglobin Proteins whose function is to fight off bacteria and viruses in your body antibodies The segment of DNA that provides the code for the formation of a protein is called a? gene The type of bond which links amino acids together in a chain is called a? peptide bond What are the base pairing rules for DNA Replication? A - T, T - A, G - C, C - G Adenine pairs with Thymine, Thymine pairs with Adenine, Guanine pairs with

3 What are the base pairing rules for Transcription (mrna synthesis)? A - U, T - A, G - C, C - G Adenine pairs with Uracil, Thymine pairs with Adenine, Guanine pairs with What are the base pairing rules for Translation (protein synthesis)? What are the four nitrogen bases found in RNA? What are the four nitrogen bases in DNA? What are three differences between DNA and RNA? What carries the amino acid to the ribosome to ensure the correct order for the protein? What is a mutation? A - U, U - A, G - C, C - G Adenine pairs with Uracil, Uracil pairs with Adenine, Guanine pairs with Uracil, Adenine, Guanine, and Cytosine Thymine, Adenine, Guanine, and Cytosine DNA is 2 strands, has the 5-carbon sugar deoxyribose, and has the nitrogen base Thymine. RNA is 1 strand, has the 5-carbon sugar ribose, and has the nitrogen base Uracil trna A change in the nucleotide sequence of DNA at even one location. What is the name of the enzyme responsible for unzipping the strands of DNA in DNA replication called? What is the name of the process of mrna production or synthesis from DNA? Helicase transcription What is the primary function of DNA in cells? to store information that tells the cells which proteins to make

4 What is the process of DNA duplicating itself called? What is the spiral structure of the two strands of DNA commonly called? Replication double helix What two things make up the backbone of DNA and RNA molecules? What type of bonds hold the two strands of DNA together? When does DNA duplicate itself? Where do the amino acids come from that are floating around in the cytosol in our cells? Where does transcription occur? Where does translation occur? Which nitrogen base takes the place of Thymine in RNA? Which nucleic acid (DNA or RNA) carries the information for protein synthesis from the nucleus to the cytoplasm? A five-carbon sugar and a phosphate group hydrogen bonds Right before the cell divides from the food we eat (digestion breaks down proteins, circulatory system transports them to our cells) in the nucleus In the cytoplasm on the ribosomes Uracil RNA (DNA is too large to fit through the nuclear pores)

5 Who were the two famous scientists given the most credit for describing the structure of DNA? James Watson and Francis Crick
