Consider the figure beow, which depicts chromatin within the neucleus of a eukaryotic cell. nucleus O The letter A indicates regions of a single chromosome which are not expressed, and the letter B indic regions of a single chromosome which are expressed. O Both answer choice A and answer choice B are correct. The letter A indicates regions of a single chromosome which are condensed and attached to the nucle lamina, and the letter B indicates regions of a single chromosome which are partially decondensed. Answer choices A, B and C are all correct.

Please help Place the images of the cell division in the right order and label them a)  What is the final product of this type of cell division? Indicate the number of dauahter cells, the TYPE OF CELLS (somatic cells? sex cells? other?), where in the body this process takes place, whether they are genetically diverse pridentical, haploid or diploid, the chromosome number in human cells, whether they contain sinale- or double-stranded chromosomes, and what the "fate" of these cells is i.e. what will they go on to do, if given the chance)?

Below is shown a recombination intermediate between two non-sister chromatids (both strands of the double helix are shown for each chromatid with one chromatid shown in grey, the other in black). A a 000 00 1 ↓ 1 and 2 1 and 4 2 and 4 1 and 3 3 and 4 2→ 2 ↑ 1 3 ↓ 4-→ - ↑ 3 -4 B At the two Holliday junctions shown, breakage and and rejoining of DNA strands are needed to allow resolution of the junctions and subsequent separation of chromatids at the end of meiosis I. Which combination of breakage sites (numbered arrows) will result in creation of the recombinant chromatids, Ab and aB? b

draw a cell with it's chromosomes showing 2n=12

Cell A is actively engaging in growth and division. The cell encounters a damage in its DNA at a certain point in the cell cycle. What would be the reaction in the cells if the damage was sensed Before the R point is passed After passing the R point What would be the similarities and differences in the reaction in the cell in cases a and b? In your answer, briefly include the significance of the R point during the cell cycle

Using a Venn diagram, compare and contrast DNA replication and DNA transcription. Make sure to include when they occur in the cell cycle and what they produce.

What is the major difference between a linkage map and a physical map of a chromosome?

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 8 picograms of DNA per nucleus. How many picograms would be found at the end of S and the end of G2?

describe the folded fiber model of the mitotic chromosome   the folded fiber model is based on each_____ consisting of single fiber wound like a skein of yarn. Each fiber consists of ___-. A cloning process occurs during the transition of _____ chromatin into more condensed chromosomes during ____ of mitosis or meiosis. Such condensation leads to 5000 folded ____ in the length of the DNA. The transition is at the end of ______ and in the beginning of ____ when the chromosomes are in the condensation process. This eventually leads to typically short and fat and chromosome.   interphase, RNA and protein, prophase, protein, DNA and protein, couple of fibers, contraction, extension, chromatid, metaphase

The value of "n" in the field mouse is 20. How many chromosomes are in a somatic mouse cell at the end of S phase? 0. 80 20 40
