What organelle contains DNA in eukaryotic cells? What feature of DNA structure allows it to replicate? What is different from one DNA nucleotide to the next? What is the phase where chromatin condenses to form chromosomes? What is the structure that allows DNA to replicate?
What is the phase where chromatin condenses to form chromosomes? Why are chromosomes not condensed during interphase? Explain why interphase is important for cell division. In which phase of the cell cycle does DNA replication occur? Answers to choose from are: G2, G0, S, G1 Please explain...
What are histones? What is chromatin? What is a chromatin? Typically, how many replication origins are formed in: a. prokaryotes? b. eukaryotes? What is DNA sequencing? If you were given a sample of chromosomal DNA and asked to determine if it is bacterial or eukaryotic, what experiment wo...
Chromatids are produced fromchromatinfibers during both meiosis and mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit w...
Finally, we have telophase: the fourth and final phase of mitosis. In telophase, the separated chromosomes start to unfold and form chromatin. The spindle also disintegrates, and a new nuclear envelope forms around the two new sets of chromosomes. These two new sets of chromosomes make up two...
The short answer to your second question is no, transcription generally does not happen at the same time as DNA replication. In eukaryotic cells, DNA replication occurs during the S-phase of the cell cycle. During S-phase, RNA transcription and protein translation are largely limited to the ...

Explain what happens during the S phase of interphase. Which of the following is part of the interphase of the cell cycle? a) S phase b) mitosis c) cytokinesis d) both (b) and (c) Name the four phases of mitosis. Briefly describe what happens in each phase of the cell cycle. a....
Describe the activity of chromosomes in each stage of meiosis 1 and meiosis 2. How does the number of chromosomes in a parent cell compare with the number of chromosomes in a daughter cell? Why is this important? Explain the difference between chromatins and chromatids, and what part of...
