Question

1 multiple choice 2 points unpacking of chromosomes and the formation of a new nuclear envelope is a characteristic of which stage of mitosis? metaphase anaphase prophase telophase 2 multiple choice 2 points a cells complete complement of dna is known as the ______________. genome chromatin rna dna polymerase 3 multiple choice 2 points a nucleotide of dna may contain ribose, phosphate, and adenine deoxyribose, phosphate, and cytosine ribose, uracil and phosphate deoxyribose, uracil and thymine

Explanation:

1. In mitosis, telophase is the stage where chromosomes unwind (unpack) and a new nuclear envelope forms around the two sets of daughter - chromosomes.
2. The complete set of an organism's DNA is called the genome. Chromatin is the complex of DNA and proteins, RNA is a different nucleic acid, and DNA polymerase is an enzyme involved in DNA replication.
3. A DNA nucleotide consists of deoxyribose (a 5 - carbon sugar), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). Ribose is in RNA nucleotides, and uracil is also an RNA - specific base.

Answer:

1. D. telophase
2. A. genome
3. B. deoxyribose, phosphate, and cytosine
