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...

Please explain
Why is a cap added to MRNA, but not to 1RNA or RRNA? Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap. Transcription and processing of MRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and...

A tryptophan tRNA gene mutates so that it recognizes one of the three possible stop codons – TGA now codes for Trp, according to the mutant tRNA. a) Will all proteins in the cell be affected by this mutation? Briefly explain your answer; if not all proteins will be affected, estimate about what fraction of proteins will be affected. b) Gene X encodes the stop with TGA. How will this mutation affect the protein X that is produced? c) Will...
