What else can I help you with?
A part of an mRNA has the sequence CCG. which change to this sequence would indicate a missense mutation?
CGG GAA
Amino acid sequence for ctg ggc tta aag cgc?
Due to the calculations you make using your genetic code dictionaries, you must go backwards using the third letter of codon and then second and then first. Then, you have your answer for what the amino acid sequence would be for cga gaa guc. Then you just flip cga and guc, keeping gaa in the middle.
How many amino acids are coded for by the sequence on side a of this DNA strand?
It depends on the length of the mRNA. Because one codon codes for one amino acid and there are three bases to a codon, the number of amino acids that are synthesized into a protein can be determined by taking the number of bases on the mRNA and dividing it by three.
What is a degenerate DNA?
Degenerate DNA refers to DNA sequences that exhibit variations in the genetic code, such as multiple codons that can code for the same amino acid. This degeneracy allows for redundancy in the genetic code, providing flexibility and robustness in protein synthesis.
What kind of mutation is this ugu-ccg-GAA-cga to ugc-cgg-GAA-cga?
The sequence TGA-GCC-ATG-A is changed in 2 places to become TGA-GCA-CAT-GA.When one base is changed, it is called a point mutation.In this case, a GCC in the DNA has been changed to a GCA. This would mean the mRNA codon (coded for by this DNA) would change from CGG to CGU.Both of these codons code for the same amino acid - Arginine. Therefore this type of point mutation is known as a silent mutation.The extra C that appears would be called an addition mutation, which is a type of frameshift mutation.
What is the redundancy codon?
Amino acids can be represented by more than one codonex. Although codons GAA & GAG both specify glumatic acid (redundancy), neither of them ever specifies for any other amino acid (no ambiguity)
What codes for the same silent point mutation?
A silent point mutation is a change in a DNA sequence that does not alter the amino acid sequence of the resulting protein. This often occurs due to the redundancy of the genetic code, where multiple codons can code for the same amino acid. For instance, both GAA and GAG codons code for glutamic acid, so a mutation from GAA to GAG would be a silent mutation. Thus, any codon that codes for the same amino acid as the original codon can be considered as coding for the same silent point mutation.
What are four examples of codons and what are the instructions they encode?
Codon is a group of three bases on a DNA molecule, each determining the identity of one amino acid in proteins made by a cell. An example of a codon is the mRNA sequence of AUG.

What is transcribe sickle cell?
To transcribe and translate the normal and sickle cell DNA you need to do the following: transcribe into RNA normal: ccc gaa gaa aaa sickle: ccc gua gaa aaa Then look in codon table normal Proline Glutamtatic acid Glutamtatic acid Lysine sicke Proline Valine Glutamtatic acid Lysine
Amino acid sequence for ctg ggc tta aag cgc?

WHAT IS THE TYPE OF MUTATION FOR GAA-CGU-AGC-GGU and GAU-CGU-AGC-GGU?
The mutation from GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU is a point mutation, specifically a substitution mutation. In this case, the first codon changes from GAA (which codes for glutamic acid) to GAU (which codes for aspartic acid). This type of mutation can lead to changes in the protein sequence, potentially affecting its function.
How many amino acids are coded for by the sequence on side a of this DNA strand?
It depends on the length of the mRNA. Because one codon codes for one amino acid and there are three bases to a codon, the number of amino acids that are synthesized into a protein can be determined by taking the number of bases on the mRNA and dividing it by three.
How does a person get their gene from GAA to GAU?
Mutation. Anyways the third letter in a codon isn't as important when translating into protein.
What is a degenerate DNA?
Degenerate DNA refers to DNA sequences that exhibit variations in the genetic code, such as multiple codons that can code for the same amino acid. This degeneracy allows for redundancy in the genetic code, providing flexibility and robustness in protein synthesis.
What change to this sequence would indicate a silent mutation?
A silent mutation occurs when a change in the DNA sequence does not alter the amino acid sequence of the resulting protein. This can happen through a substitution of a nucleotide that still codes for the same amino acid due to the redundancy of the genetic code. For example, if the original sequence is "GAA" (which codes for glutamic acid) and it changes to "GAG," this would represent a silent mutation since both codons code for the same amino acid. Thus, the change in the sequence that doesn't affect the protein's amino acid sequence indicates a silent mutation.
Which triplet in DNA codes for glutamate?
GAA and GAG code for Glutamic Acid.
