During transcription the DNA base sequence is transcribed into a complementary mRNA sequence. A codon table like the one shown b
elow lists the amino acids coded for by particular triads of mRNA bases. A segment of DNA has undergone a mutation in which one nucleotide has been changed. The original sequence was ACG and the new sequence is ACA. Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism. Group of answer choices
a. yes, the phenotype of the organism would change because a new amino acid will be coded for.
b. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
c. It is impossible to determine if a change in phenotype will occur using only the DNA sequence.
d. yes, the phenotype of the organism would change because any change in the DNA sequence will cause a change in phenotype
b. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
There is redundancy in the genetic code. That means that different codons can code for the same amino acids, so some mutations do not change the amino acid sequence of the protein.
Here, the amino acid is unchanged with the mutation.
If the amino acid sequence of the protein is the same, then the protein is not changed, so there will be no change in the phenotype
An SOP is a procedure specific to your operation that describes the activities necessary to complete tasks in accordance with industry regulations, provincial laws or even just your own standards for running your business.
Answer: linear or circular. include genes encoding viral proteins: capsid, envelope proteins, any polymerase not found in the host cell. viruses may have a lipid envelope.
