Answer:
all of these affect enzyme activity
Answer:
The mentioned case is an illustration of the missense mutation. A missense mutation is a kind of nonsynonymous substitution, that is, it is a mutation in which a variation in a solitary nucleotide leads to the formation of a codon, which encrypts for a distinct kind of amino acid.
When a missense mutation takes place within a DNA, a modification in one of the RNA codon sequences results at the time of transcription. This change in codon will ultimately result in the formation of a different amino acid, which gets presented within a protein at the time of translation. Like in the given case, a change in codon resulted in the substitution of the amino acid tyrosine with an amino acid cysteine.
Chromosomes makes up genes while genes and chromosomes make up the entirety of DNA. A living organism inherits 46 chromosomes, 23 from each parent. These chromosomes are not genes but they form genes, which are just the traits of an individual that are unique. DNA is the entire make up of an organism that controls everything about a person such as likelihood to have disease or their physical appearance.

The generally widely accepted first step of the scientific method is to ask a question.
This is where you think of a question which you want to do an experiment on, and then later on conduct an experiment to answer that question.
