BIO 110 WAKE TECH EXAM 2 STUDY GUIDE | GENERAL BIOLOGY PRACTICE QUESTIONS AND
ANSWERS | COMPLETE EXAM REVIEW
Transcription - ANS ✔✔A process where DNA sequence in a gene is copied into mRNA
Translation - ANS ✔✔A process where mRNA is decoded and a protein is produced
Translation + Transcription Steps - ANS ✔✔Initiation, elongation, and termination
Chargaff's rules, the base-pairing rules, state that in DNA: - ANS ✔✔A=T and C=G
The end product of translation is: - ANS ✔✔Protein
Difference between DNA and RNA - ANS ✔✔DNA: Deoxyribose Sugar, AT, CG, Double-stranded,
Remains in the Nucleus;
RNA: Ribose Sugar, AU, CG, Single-stranded Helix, Found in Nucleus and Cytoplasm
Role of Transfer RNA (tRNA) - ANS ✔✔To decode information.
Consists of two processes:
1. tRNA must covalently bind one amino acid;
2. tRNA must be able to recognize the codon.
tRNA and mRNA - ANS ✔✔-mRNA transcribes, tRNA translates
-mRNA nucleus, tRNA cytoplasm
-mRNA carries the message, tRNA picks up amino acids
