The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.

Explanation:

mRNA is formed by the transcription of DNA strand coding for  a gene.

Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.

The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.

In transcription 3' to 5'  strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is

3'TTT AAC   GTC    ATC 5'    Gene sequence

5' AAA UUG CAG   UAG 3'   mRNA

lysine, leucine, Glutamine, stop

boyakko [2]

Answer:

homologous

Explanation:

<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>

Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.

The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.

The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
