Question

rna is used in the process of translation to build proteins. which of these statements does not correctly describe the role of the different types of rna in protein synthesis?
trna carries amino acids to ribosome.
rrna makes up the ribosome.
trna carries nucleotides to the ribosome.
mrna copies the genetic code from dna and carries it to the ribosome.
mrna code is read to determine the sequence of amino acids in the protein.
multiple choice 8 points
a student makes a claim that a cell is undergoing the process of transcription. what evidence would be present to support this claim?
dna polymerase is using both strands of dna to produce multiple mrna molecules.
rna polymerase is using a single strand of the dna molecule as a template for mrna production.
ribosomes are reading mrna molecules three nucleotides at a time to synthesize proteins.
trna with anticodons is carrying amino acids to the ribosome.

Explanation:

For question 8: In protein synthesis, tRNA carries amino - acids, not nucleotides, to the ribosome. rRNA makes up the ribosome, mRNA copies the genetic code from DNA and its code is read for amino - acid sequence determination.
For question 9: Transcription is the process where RNA polymerase uses a single strand of DNA as a template to produce mRNA. DNA polymerase is for DNA replication, and the processes involving ribosomes and tRNA are part of translation.

Answer:

1. C. tRNA carries nucleotides to the ribosome.
2. B. RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production.
