Analyzing mRNA Sequences
1. Analyze the following amino acid sequence and write
down a potential mRNA sequence from which this
sequence might have been translated. Use the codon table
in your book to determine a possible mRNA sequence.
Amino Acid Sequence 1:
H,N*-Methionine-Valine-Histidine-Leucine-
Threonine-Proline-Glutamic Acid-Glutamic Acid-
COO
2. (a) Consider Amino Acid Sequence 2. How is Amino
Acid Sequence 2 different from Amino Acid Sequence 1?
Amino Acid Sequence 2:
H,N*-Methionine-Valine-Histidine-Leucine-
Threonine-Proline-Valine-Glutamic Acid-CO
(b) Write a potential mRNA sequence for Amino Acid
sequence 2, using the same codons for any given amino
acid if it is present in both sequences.
Open reading frames...
correspond to introns, which are not read by the ribosome during translation
correspond to contiguous fragments of DNA sequence that do not contain a stop codon when read in a particular frame
correspond to contiguous fragments of DNA sequence that do not contain a stop codon when read in any of six frames
are often rich in acetylated histones which allow transcription
occur when fragments of DNA sequence are highly similar between two species
are recognized by ribosomes to initiate translation
WHAT IF? DRAW IT Draw a tRNA with the anticodon3¿-CGU-5¿. What two different codons could it bind to?Draw each codon on an mRNA, labeling all 5¿ and 3¿ends, the tRNA, and the amino acid it carries.
