Answer:

The order of the codons differs between organisms.

Explanation:

The four nitrogenous bases, guanine, thymine, adenine, cytosine (and uracil in RNA) are present in all living beings, forming pairs that are able to define our genetic characteristics. Nitrogen bases can have 64 different combinations, so there are 64 different codons. Of these codons, 61 will encode the 20 different types of amino acids in existence. The order that these bases are and the order that each codon is within the DNA is the factor that determines why there is so much variability among living things.

<h2>Answer:</h2>

Because same base pairs are arranged differently among organisms due to which there are so much variations in organisms.

<h3>Explanation:</h3>

Variation in the organism is due to the genes.
Every one have different DNA/genes which describes one's features.
Genes are various arrangements of these four base pairs.

So same base pairs with different pattern arrangement causes variation among organism.

A point mutation is shown in the mutated DNA sequence below. Will this mutation affect the

klemol [59]

Answer:

A. Yes, because an amino acid change has occurred.

Explanation:

The sequence given states that the codon CCG is changed to CAG. According to the codon table (attached), CCG codes for <u>proline</u> whereas CAG codes for <u>Glutamine</u>. Therefore, change in mutation has resulted into the change in amino acid. This would lead to the formation of a different protein.
