During proofreading, which of the following enzymes reads the DNA?
Stells [14]

Answer:

DNA pol

Explanation:

DNA polymerases (DNA Pol) are enzymes present in both eukaryotic and prokaryotic cells. These enzymes are responsible for the synthesis of complementary DNA molecules. These enzymes are essential for DNA replication and generally work by using an individual DNA strand as a template to synthesize a complementary strand, so DNA polymerases are DNA dependent.

During the proofreading, DNA polymerase is the enzyme that has the function of reading the DNA.

Species
Setler79 [48]

Answer:

D. Human and Chimpanzee are more related than any other pair

Explanation:

The image in this question shows a tabularized information on the amino acid sequence of hemoglobin protein in different species. This amino acid sequence can be used to deduce whether two or more species are closely related or not. The amino acid sequence of the hemoglobin of the different organisms are as follows:

- Human: Lys-Glu-His-Iso

- Horse: Arg-Lys-His-Lys

- Gorilla: Lys-Glu–His-Lys

- Chimpanzee: Lys-Glu-His-Iso

- Zebra: Arg-Lys-His-Arg

Based on the above sequences, it can be observed that the amino acid sequence of humans and chimpanzee are the same with little to no differences while other species that have similar sequences differ in one or two amino acids. This means that Human and Chimpanzee are more related than any other pair.
