DNA and protein synthesis

Which base pairs follow the complementary rule in DNA?

• A-T and G-C

• A-G and C-T

• A-C and G-T

• A-A and G-G

What would be the mRNA sequence transcribed from the DNA sequence ATGGCCTAA?

• UACCGGAUU

• TACCGGATT

• AUGGCCUAA

• ATGGCCTAA

Which claim best describes the relationship between DNA structure and protein synthesis?

• The sugar-phosphate backbone of DNA directly produces protein

• Base pairs in DNA connect randomly to form protein

•  Complementary base pairing ensures accurate order of amino acids

• DNA base pairs directly form the protein

Which contains the correct order of protein synthesis?

• DNA → protein → mRNA → tRNA

• DNA → mRNA → tRNA → protein

•  mRNA → DNA → protein → tRNA

• tRNA → mRNA → DNA → protein

The final product of gene expression is:

• DNA

• mRNA

• tRNA

• Protein

The sequence of amino acids in a protein is determined by

• The cell membrane

• The genetic code in DNA

• The number of ribosomes

• The amount of energy available

RNA contains the sugar

• ribose
• deoxyribose
• glucose
• lactose

I am a single strand.

• DNA
• RNA

Which of the following is the correct order of molecules?

• DNA -> RNA -> Proteins
• Proteins -> DNA -> RNA
• RNA -> DNA -> Proteins
• There is no specific order of these molecules

What is the difference between DNA and RNA in terms of bases?

• RNA contains uracil in place of thymine
• RNA contains uracil in place of adenine
• RNA contains uracil in place of guanine
• RNA contains uracil in place of  cytosine
