Use the table to answer the question below. A mutation causes the following change in DNA. Original DNA sequence: T A C G C A T G G A A T DNA sequence after mutation: T A C G T A T G G A A T Which amino acid substitution will result from this point mutation? Arg is replaced by Met Tyr is replaced by Thr Arg is replaced by His His is replaced by Ala

Arg is replaced by His

Explanation:

When finding the complementary RNA your first bases would be AUG-CGU-ACC-UUA. For the mutated sequence it would be AUG-CAU-ACC-UUA. Now you use the corona chart and get that the original sequence would’ve been ARGININE and the mutated sequence is HISTIDINE. In case you need the RNA : Leucine-Arginine-Threonine-Leucine MUTATED: Leucine-Histidine-Threonine-Leucine

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

i think the answer is a.keratin is the pigment responsible for skin color.
