From prophase through metaphase of mitosis, each chromosome has _____ DNA molecule(s), while from anaphase through telophase of
steposvetlana [31]

From prophase through metaphase of mitosis, each chromosome has 2 DNA molecule(s), while from anaphase through telophase of mitosis, each chromosome has one DNA molecule.

Explanation:

Mitosis is a process in which 2 identical daughter cells are formed in which DNA gets split into two sets of chromosome.

Mitosis occurs in four phases: Prophase, metaphase, Anaphase and Telophase.

After the G2 phase the DNA amount increases and get ready for the division here sister chromatid are seen not chromosome.

In metaphase the chromosome align at the equatorial plate and readied to separate the sister chromatids easily. Each chromatid contains 1 DNA molecule, in this phase two sister chromatids are there so 2 molecules of DNA are present.

In Anaphase the sister chromatids are pulled towards the opposite ends. Each cell receives one chromatid which is now 2 chromosmes. So one chromatid will have one DNA molecule.

This cladogram compares the protein sequence of Cytochrome C. The percent numbers indicate matches in sequence.
jok3333 [9.3K]

Cytochrome C is a homologous protein and developed from a common ancestor is the correct interpretation of the graphic.

<h3>What is a Cladogram?</h3>

This is a diagram which describes the relationships between different groups of taxa which are referred to as clades.

Since all the organism have some form of similarity in the protein  sequence then it means that they came from a common ancestor.
