Question

kai looks at a photo of herself with her parents. she notices that, while her features are similar to her parents features, they do not appear to be identical. which explains why this is the case? their dna is made of different codon sequences. their dna is made of four different bases. kai inherited more proteins from one parent than the other. kai inherited different amino acids from either of her parents.

Explanation:

• Option 1: Different codon sequences in DNA lead to different genetic information being encoded. Since codons code for proteins (which influence traits/features), different codon sequences can result in Kai having features similar but not identical to her parents.
• Option 2: All DNA (in all organisms) is made of four different bases (adenine, thymine, cytosine, and guanine). This is a general property of DNA and does not explain the difference in features between Kai and her parents.
• Option 3: Inheritance is based on genes (segments of DNA), not on proteins. Proteins are made from the information in genes.
• Option 4: The set of amino acids used in protein synthesis is the same for all organisms (in most cases). The difference in features is not due to inheriting different amino acids.

Answer:

Their DNA is made of different codon sequences.
