Question
RNA has many different roles in gene expression. Check all that apply.
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 transfers the code from DNA to RNA, though in complementary fashion.
True
False
The template strand is to the sense strand as the coding strand is to the antisense strand.
True
False
The phenomenon symbolized by DNA RNA Protein is referred to as the Central Dogma because it is true for all organisms.
True
False
The reading frame refers to the selection of the correct triplet of nucleotides by selecting the correct beginning point. If the beginning point is wrong, all nucleotides will be clustered into the wrong codons.
True
False
Activating enzymes need to recognize only one anticodon.
True
False
Explanation / Answer
1. The correct statements are:
mRNA defines the polypeptide to be formed
DNA defines the polypeptide to be formed but indirectly.
rRNA, along with proteins, forms the ribosome
tRNA delivers the appropriate amino acid to the ribosome
2. False.
Transcription is the transfer of information from DNA to RNA. The processing of codons present on the mRNA to produce proteins is called translation.
3. False.
The sense strand and the coding strand are the same. The antisense strand acts as the template for DNA transcription.
4.TRue.
5. TRue.
6. TRue.
