DNA & Protein Synthesis assessment/studyguide

What is the complement to the following DNA strand if DNA replicates itself? TAT-TAG-ATT-ACA

• TAT-TAG-ATT-ACA

• ATA-ATC-TAA-TGT

• UTU-UTC-TUU-TGT

• ATA-UTC-UAA-TGT

What is the role of DNA polymerase in DNA replication?

• DNA polymerase replicates tRNA, mRNA & rRNA.

• DNA polymerase adds A-U-G-C as compliments to the original DNA stand to make an identical copy.

• DNA polymerase "unzips" the DNA.

• DNA polymerase adds complimentary free nucleotides to the original strand to make an identical copy.

Which of the following is true about the structure of RNA?

• Its sugar is ribose

• It contains Thymine

• Its sugar is Deoxyribose

• It is double stranded

Which table shows two steps of DNA replication?

• Step 1: DNA Polymerase matches uracil to thymine and cytosine to guanine.

  Step 2: Two identical DNA double helices are produced.

• Step 1: DNA Polymerase matches cytosine to thymine and uracil to guanine.

  Step 2: Two separate but complementary single DNA strands are produced.

• Step 1: DNA Polymerase matches adenine to thymine and cytosine to guanine.

  Step 2: Two identical DNA double helices are produced.

• Step 1: DNA Polymerase matches uracil to thymine and adenine to guanine.

  Step 2: Two separate but complementary single DNA strands are produced.
