Inside each cell, there's a ___ that stores your DNA. How can DNA be transcribed to RNA? Where can DNA be found in a eukaryotic cell besides the nucleus? Does any DNA ever leave the nucleus during DNA replication? What is the type of cell in which most DNA is found in the nucleus...
Each cell’s fate is largely determined by chemical modifications to the proteins that decorate its DNA; these modifications in turn control which genes get turned on or off. When cells copy their DNA to divide, however, they lose half of these modifications, leaving the question: How do cell...
The story of the control system by which all these activities are regulated by the cell is absorbing one, and shows the remarkable complexity of the mechanisms of the hierarchy of DNA binding proteins which govern the reproductive activities of what appears to be a simple yeast cell....
In eukaryotes, to contain the DNA inside the nucleus, it is wrapped around nuclear proteins called histones. The DNA, along with the histones, is then wrapped into a 30 nm spiral called: ANSWERS OPTIONS A Nucleosome B Solenoid C Chromatin ...
DNA is transcribed into RNA, which becomes translated into proteins. The first step of gene expression, transcription, occurs in the cell nucleus assisted by the intricate interplay of molecular machinery that acts on chromatin, the functional form of DNA inside cells (Van Holde 2012; Alberts et...
The cell pellet was washed twice with PBS. Genomic DNA was isolated using the Easy-DNATM kit (Invitrogen, Life Technologies, Carlsbad, CA) according to the manufacturer's instructions. Expression and Purification of Recombinant Proteins Fragments of genes encoding putative surface localized proteins ...
We report here crystal structures of human 8-oxoguanine (oxoG) DNA glycosylase, hOGG1, that interact with the DNA containing the damaged base oxoG and the normal base G while they are nested in the DNA helical stack. The structures reveal that hOGG1 engages the DNA using different protein-...
The chromosomes and genes are made of DNA, which is short for deoxyribonucleic acid. Chromosomes are found inside cells, the very small units that make up all living things. A cell is so tiny that you can only see it through the lens of a strong microscope, and there are billions of ...
Plant mitochondrial genomes can be complex owing to highly recombinant structures, lack of gene syntenies, heavy RNA editing and invasion of chloroplast, nuclear or even foreign DNA by horizontal gene transfer (HGT). Leptosporangiate ferns remained the l
我了解到这些DNA结并非总是坏事。 事实上,打结和解结—— 有点像复杂的电脑语言, 它精确地控制着我们的身体。So when we get pregnant, our fertilized eggs grow into newborn babies. This process requires thousands of DNA decisions to happen. Should an embryo cell become a blood cell? A heart cell...
