Suppose that part of an amino acid sequence of a protein changed from tyrosine-proline-glycine-alanine to tyrosine-histidine-glycine-alanine. This change was most likely caused by a point mutation called a <u>substitution</u>.
<u>Explanation:</u>
Any protein is synthesized by joining a number of amino acids together. This amino acid is placed based on the sequences of the DNA , for every 3 sequence there is an amino acid that is synthesized and therefore it is called as a triplet codon, since there may be many sequence for a single amino acid we call it as degenerate codon.
Meiosis (SEXUAL cell division) is a type of Mitosis (cell division).
Diploid cell production happens during meiosis when the haploid (n) cells from the parents divide into TWO diploid (2n) cells (which have the complete set of chromosomes from the parents).
Basically, meiosis is required for sexual reproduction (unless in your question you can choose more than one answer...so it'll be meiosis, diploid cell production, mitosis)
The answer is C. thousands of galaxies

So, it has to be thousands.</span>
