TAC GGA TCG GGA TAT CAT - ANS AUG CCU AGC CCU AUA GUA
During gene expression, _______ is/are the major cellular component associated with
transcription and ______ is/are associated with translation - ANS RNA polymerase,
ribosomes
Place the following of gene expression in the correct order:
1. A new protein is synthesized, which can affect an organism's physical traits, behavior, or
physiology (aka phenotype)
2. tRNA molecules bind to mRNA condons linking amino acids in a precise sequence
3. an mRNA molecule exists the nucleus and finds to a ribosome in the cytoplasm of the cell
4. RNA polymerase binds to the DNA template strand in the nucleus and produces a
complementary mRNA molecule - ANS 4,3,2,1
What is the end product of gene expression? - ANS a protein
DNA sequence of: TAC ACC TTG GCG ACG ACT - ANS 3rd TAC ACC TTA GCG ACG ACT
