- Consider the following DNA molecule (shown in the picture) and assume this is the DNA sequence of the entire chromosomes. list the amino acid sequences of the possible protein or proteins that could be produced from this DNA sequence what would be the DNA sequence of a sister chromatid generated from this chromosome sequence? (specify the 5' nd 3' ends)A diploid (ie, contains TWO sets of chromosomes) organisms with a 45,000-kb haploid (counts only one set of its chromosomes) genome contains 21% G residues. Calculate the number of A, C, G< and T residues in the DNA of each cell in this organism. Can you help explain why this is the answer, thank you! Answer: Since the haploid genome contains 21% G, it must contain 21% C (Because G=C) and 58% A + T, or 29% A and 29% T. Each cell is a diploid, containing 90,000 kb or 9x10^7 bases. Therefore, A=T = (0.29)(9x10^7) = 2.61 x 10^7 bases and G=C=(0.21)(9x10^7) = 1.89x10^7 bases.The haploid human genome consists of approximately 3.2 × 109 bp (or 6.4 × 109 bp per diploid genome). Assuming that DNA is B-DNA, calculate the total length of a single cell’s DNA.
- A previously undiscovered single-cell organism was found living at a great depth on the ocean floor. Its nucleus contained only a single linear chromosome with 7 x 106 nucleotide pairs of DNA coalesced with three types of histone-like proteins. Consider the following questions: Question: The analysis of individual nucleosomes reveals that each unit contained one copy of each protein and that the shortlinker DNA contained no protein bound to it. If the entirechromosome consists of nucleosomes (discounting any linkerDNA), how many are there, and how many total proteins areneeded to form them?Cell (A) contains 3.1 billion (3.1 x 109) base pairs of DNA. Each nucleosome has about 200 bp of DNAwrapped around the histone core.a. What is the maximum number of nucleosomes that can be present in the cell?b. What is the maximum number of H2A histone protein molecules that can be present in the cell?|(big/ prokaryote / eukaryote), which lack membrane bound prganelles and a nucleus and (small/ prokaryote / eukaryote), which contain membrane bound organelles. The nucleus of eukaryotic cells separated from the cytoplasm by a (cellular / nuclear / sticky) envelope. The hereditary material is in the nucleus. It exists as (DNA only / histones only/ chromatin) until the cell divides and then we see chromosomes.
- All of the following statements regarding nucleosomes are true EXCEPT A each bead-like structure contains 8 molecules of histones H1, H2A, H2B, H3 and H4 the bead like structures are made up of core histones wrapped around by the DNA strands the histone proteins in the nucleosomes contain positively charged amino acids that interact with the negatively charged DNA D the bead like structures are linked to each other by the DNA chainDescribe the structure of nucleosome ( please keep it short as much as you can ) .If a human nucleus is 10 mm in diameter, and it must hold as much as 2 m of DNA, which is complexed into nucleosomes that during full extension are 11 nm in diameter, what percentage of the volume of the nucleus does the genetic material occupy?
- In a turtle species, a diploid cell in the G1 phase of the cell cycle contains 22 picograms of DNA (picogram is a measure of the total mass of the DNA present). How much DNA is present in a cell of the same species at prophase II of meiosis (prophase of the second meiotic division)?Mammals contain a diploid genome consisting of at least 109 bp. If this amount of DNA is present as chromatin fibers, where each group of 200 bp of DNA is combined with 9 histones into a nucleosome and each group of 6 nucleosomes is combined into a solenoid, achieving a final packing ratio of 50, determine (a) the total number of nucleosomes in all fibers, (b) the total number of histone molecules combined with DNA in the diploid genome, and (c) the combined length of all fibers.A previously undiscovered single celled organism was found living at a great depth on the ocean floor. Its nucleus contains only a single, linear chromosome consisting of 7x10^6 nucleotide pairs of DNA coalesced with three types of histone-like proteins. The analysis of individual nucleosomes revealed that each unit contained one copy of each protein and that the short linker DNA had no protein bound to it If the entire chromosome consists of nucleosomes (discounting any linker DNA), how many are there and how many total proteins are needed to form them?
