5' C U A C C U C A G A U U C G C C U A C C U 3'
a.What is the DNA sequence that encodes for the word for this protein? Be sure to note the 5' and 3' ends. I would appreciate the help! Thanks!
To determine the DNA sequence that encodes for a specific protein, you need to understand the genetic code. The genetic code is a set of rules that specifies how the sequence of nucleotides in DNA (or RNA) is translated into the sequence of amino acids in a protein.
Each amino acid is represented by a specific codon, which consists of three nucleotides. To determine the DNA sequence that encodes for a protein, you need to identify the codons corresponding to each amino acid in the protein sequence.
Let's go through the process step by step using the given protein sequence "C U A C C U C A G A U U C G C C U A C C U."
1. Start by identifying the codon for each amino acid in the sequence:
C U A C C U C A G A U U C G C C U A C C U
2. Refer to a genetic code table to find the corresponding codons for each amino acid. Here is a common example of a genetic code table for RNA:
C U A C C U C A G A U U C G C C U A C C U
L U I T L S T V E I P L T
Therefore, the RNA sequence that encodes for the given protein is "CUACCUCAUAUUCGCCUACCU" (3' to 5' direction).
However, since DNA is our starting point, we need to convert this RNA sequence into its complementary DNA sequence.
To do this, you need to apply base-pairing rules where adenine (A) binds with thymine (T) and cytosine (C) binds with guanine (G).
The complementary DNA sequence for "CUACCUCAUAUUCGCCUACCU" would be:
5' GAUGGAGUAUAAAGCGGAUGGA 3'
Therefore, the DNA sequence that encodes for the given protein is 5' GAUGGAGUAUAAAGCGGAUGGA 3' (note the 5' and 3' ends).
Remember to always double-check your work and consult reliable sources for genetic code tables to ensure accuracy.
