Chromosomes are structures of packaged DNA sequences, that are passed onto daughter cells during cell division. The sister chromatids of chromosomes are held together at the middle by the centromere, which also consists of DNA.Answer and Explanation: ...
The main proteins of the nucleoid are: RNA polymerase, topoisomerases and the histone-like proteins: HU, H-NS (H1), H, HLP1, IHF and FIS. ... DNA supercoiling is generated by the activity of the topoisomerases and by DNA-protein interactions. What is the function of slime layer?
Indeed, following UV-exposure, histone acetylation takes place and is believed to facilitate the nucleotide excision repair (NER) process by promoting chromatin accessibility to the repair factors. This review focuses on recent data characterizing the function of histone modification in various repair ...
Within eukaryotic cells chromatin plays an important role in the regulation of gene expression. Nucleosomes form the fundamental repeating unit within chromatin. Nucleosomes consist each of the four core histones around which ~146 basepairs of DNA is wrapped. Both DNA and histone proteins carry addi...
