Question

by the early 1950s, many biologists realized that the key to understanding inheritance lay in the structure of: dna chromosomes protein histones ribosomes question 11 1 pts in mitosis, the nuclear membrane re - forms around each new set of chromosomes during: prophase telophase anaphase metaphase

Explanation:

• For the first question: DNA is the molecule that carries genetic information and is the key to understanding inheritance. Chromosomes contain DNA but the focus here is on the molecule itself. Proteins, histones (a type of protein associated with DNA), and ribosomes (involved in protein synthesis) are not the key to inheritance in the way DNA is.
• For the second question: In mitosis, during telophase, the nuclear membrane re - forms around each new set of chromosomes. In prophase, the nuclear membrane breaks down. In anaphase, chromosomes are separated and move to opposite poles. In metaphase, chromosomes line up at the equatorial plane.

Answer:

1. DNA
2. telophase
