QUESTION 6 The DNA sense (coding) strand for a particular amino acid is 5'-CAT-3'. What RNA sequence would be transcribed for this codon, what tRNA anticodon would recognize it, and what amino acid would be added in response to this codon? O 5'-UUU-3' (RNA sense); 3'-AAA-5' (tRNA anticodon); phenylalanine O 5'-CAU-3' (RNA sense); 3'-GUA-5' (tRNA anticodon); histidine O 5'-CAU-3' (RNA sense); 3'-AUG-5’ (tRNA anticodon); tyrosine O 3'-AUG-5' (RNA sense); 3'-UAC-5' (TRNA anticodon); valine QUESTION 7 The “wobble” base is less...
Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
Question 2 (1 point) In order to target a protein to the endomembrane system, which of the following is required first?

Which codon in the mRNA would the tRNA recognize: the one...

location of the -10 consensus sequence?
4.) How many amino acids long is the protein encoded by the mRNA
from this DNA sequence?
