During transcription the DNA base sequence is transcribed into a complementary mRNA sequence. A codon table like the one shown below 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

Answer:

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

2. Hank passes by a building every day on his way to school. He notices that the
rock used to build the walls of the building is a different type than the rock
used to build the steps. How could energy have played a role in the different
rock types forming?
a Energy from different sources leads to different types of rock. Energy inside
Earth melts rock into liquid rock, but energy from the sun causes rock to
weather into small pieces of rock.
b Energy causes different types of rock to change in different ways. Energy
changes igneous rock into liquid rock and changes sedimentary rock into
small pieces of rock.
c Energy caused one rock type to form, but not the other. Rock that forms
because of energy is a different type of rock than rock that forms without
energy.
d Energy changes rock on different continents in different ways. Each
continent on Earth has different rock that might form liquid rock or small
rock pieces when exposed to energy.
