RNA has many different roles in gene expression. Check all thatapply.
mRNA defines the polypeptide to be formed
DNA defines the polypeptide to be formed
rRNA, along with proteins, forms the ribosome
mRNA delivers the appropriate amino acid to the ribosome
tRNA delivers the appropriate amino acid to the ribosome
Translation is appropriately named because the process transfersthe code from DNA to RNA, though in complementary fashion.
True
False
The template strand is to the sense strand as the coding strandis to the antisense strand.
True
False
The phenomenon symbolized by DNA â RNA â Protein is referred toas the Central Dogma because it is true for all organisms.
True
False
The reading frame refers to the selection of the correct tripletof nucleotides by selecting the correct beginning point. If thebeginning point is wrong, all nucleotides will be clustered intothe wrong codons.
