What is the difference between chromatin and chromosomes? How many DNA molecules are in a eukaryotic chromosome in its duplicated form? Why? What proteins are used to spool up DNA? What charge do they have? 1. What is the complementary strand for: 5'-ATGCATGCATGCCC-3'? How many turn(...
Which of the following choices most accurately describes the proteins that form the linker histones of the chromatosome? A) H2A, H2B, H3, H4 B) H2A, H1t, H5, H3 C) H5, H1a-e, H1t, H10 Which is not a type of protein? A. Simple Protein B. Complex Protein C. Conjugated Protein ...
DNA is far more condensed. Proteins called histones form from four pairs of subunit proteins (eight subunits in all). This octamer serves as a spool of sorts for the DNA double helix to wrap itself around twice, like thread. This structure, the octamer plus the DNA wrapped around it, is...
H2A.Z the “good guy”: Counteracting the oncohistones In most diseases where H2A.Z is involved, its overexpression or improper modification tends to be detrimental, often exacerbating the condition. However, there is a notable exception where H2A.Z plays a beneficial role. In pediatric high-gra...
Organisms can be broadly categorized as eukaryotic or prokaryotic largely based on whether a nucleus containing DNA is present. In eukaryotic organisms, DNA andhistones(proteins) coil together, forming chromosomes. Each chromosome in a diploid cell is part of a homologous pair. Reproductive germ cells...
DNA molecules are so long they cannot fit into cells without being packed in a very specific way. To do this, it is coiled tightly around ball like proteins called histones. The tightly woundDNA structurecreates a thread-like shape called achromosome. ...
Most of the eukaryotic genomic DNA is bent around histones to form nucleosomes. The capacity of the DNA sequence to undergo such distortion can influence the specific preferred locations for many of the nucleosomes. The existence of a cancerous lesion can sometimes be detected through the ...
Epigenetic modifier complexes which methylate histones c. Nuclear pore complexes which phosphorylate the Within the ETC (electron transport chain) of metabolism, there are complexes that contribute to the ETC process. What are the major electron carriers within these complexes? What is the carboxyl ...
