What type of bond holds the nitrogen bases together in DNA?

• weak nitrogen bonds

• weak hydrogen bonds

• strong hydrogen bonds

• strong nitrogen bonds

How is the genetic information from DNA Transcribed?

• Information cannot travel outside of the nucleus

• Information is attached to a carrier protein to get across the nuclear membrane

• Information is copied onto a tRNA molecule and travels through a nuclear pore

• Information is copied onto a mRNA molecule and travels through a nuclear pore

What enzyme unzips the DNA

• DNA Helicase

• DNA Polymerase

• tRNA

• peptase

What are the differences between DNA and RNA? (check all that apply)

• DNA stay in the nucleus; RNA travels to the cytoplasm

• DNA has base Uracil; RNA has base Thymine

• DNA is double stranded; RNA is single stranded

• DNA has base Thymine; RNA has base Uracil

What is the purpose of the diagram?

• To replicate DNA before cell division

• To assemble nucleotides into mRNA

• To synthesize amino acids

• To translate the genetic code into a specific sequence of amino acids

How many nitrogen bases make up a codon?

• as many as possible

• 3

• 2

• 1

During translation, the ribosome is the site where...?

• DNA helicase seperates and copies the DNA

• amino acid chains are assembled into proteins

• information from DNA is copied into mRNA

• free floating amino acids are picked up by tRNA

What type of mutation is shown here?

• Substitution

• Insertion

• Deletion

• Point mutation
