How does transcription differ from translation? Choose all that apply (2)

Translation uses mRNA to code for amino acids and transcription uses DNA to synthesize mRNA

Translation uses DNA directly and Transcription does not

Transcription occurs in the nucleus and translation occurs at the ribosome

Translation occurs in the nucleus and transcription occurs in the cytoplasm

Write the mRNA codon and amino acid that would be coded by the DNA sequence GAA

Use all caps for the mRNA codon, use lower case and write out the amino acid name
Ex. CAT, proline

Which represents Chargaff's (base pair) rule

The amount of adenine=The amount of thymine

Thymine can bind with either adenine or guanine

The amount of adenine=The amount of guanine

The amount of cytosine=The amount of adenine

Place a dash in between each amino acid and spell out the amino acid names, all lower case letters
Ex. proline-valine-tryptophan

List two of the mRNA codons that will end protein synthesis
Use all capital letters and a comma in between each of the codons

Ex. CAT, GTA
