RNA – Final Exam Study Guide: Structure, Function & Protein Synthesis
Comprehensive Review Material
what is RNA - ANS ✔✔ribonucleic acid
polymer of rna nucleotides
single stranded
4 bases: uracil, adenine, cytosine, guanine
brings about formation of a protein coded for by DNA of a particular gene
What is the central dogma of molecular biology? - ANS ✔✔information is transferred from
triplet code in DNA (replication) to codons in mRNA (transcription in nucleus) to proteins and
amino acids (translation to cytoplasm)
that determines structure and function
What replaces thymine in RNA? - ANS ✔✔Uracil (U)
what is messenger RNA (mRNA)? - ANS ✔✔takes genetic message from DNA in nucleus to
ribosomes in cytoplasm.
What is an anticodon? - ANS ✔✔the tRNA complement to the mRNA codon
What is a codon? - ANS ✔✔group of 3 mRNA bases
parts of a structural gene - ANS ✔✔transcribed region: contains info that specifies an amino
acid sequence
regulatory sequence: site for binding of regulatory proteins, influences rate of transcription and
found in a variety of locations
promoter: site for rna polymer binding signals start of transcription
