Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five
species and humans. Although the DNA sequence of each may vary, all BUT ONE statement concerning the organisms is true,
A)
The same nitrogen bases are found in all six organisms.
B)
The steps in proteins synthesis are identical in all six organisms.
The DNA sequences may vary but the amino acid sequences are identical
D)
The process of producing new DNA, or replication, is identical in each.

Respuesta :

The correct option to this question will be 'C' i.e., Gorilla Gorilla.

As the number of Differences of the amino acids representing for the beta-haemoglobin is less than other 5 species from humans, so we can say that Gorilla is closely related on the basis of molecular data given in the question. The beta Haemoglobin Gene is responsible for coding a protein which is called beta-globin. Each cell present in humans contains two genes of beta-globin.
