25 (a) Explain how the nucleotides in a DNA molecule are arranged as two polynucleotide strands.(i) The human genome contains 3.0 × 10^9} nucleotides. The replication of DNA takes six hours in some cells.One eukaryotic enzyme complex can replicate DNA at a rate of 50 nucleotides added pe...
How does DNA know if it is an exon or intron? Introns and Exons in DNA: The genome of eukaryotes contains both coding and non coding regions of DNA. The coding regions, called exons, are used in the final mRNA template while the non-coding regions, introns, which are not used in the...
How the structure of DNA contributes to a cell's ability to replicate it? How does the structure of DNA fit its function, especially as it relates to DNA replication? Describe how eukaryotic DNA is arranged in the cell. How does supercoiling take place in eukaryotic DNA?
It was known already that there was an intermediary between the gene, which is DNA, and the protein, which is called mRNA or messenger RNA. We hear about mRNA today because of Covid, but at that time, it was still a mystery. This messenger RNA, which has all the information of the ...
Entire GenomeBiological InformationFieldLiving CellsThe four nucleotides (bases), A. T. G and C were sophisticatedly arranged in the structural features in a single-strand of genomic DNA, 1) reverse-complement symmetry of base or base sequences, 2) bias of four bases, 3) multiple fractality ...
each of which is attached to a pentose sugar and a phosphate molecule. Together, they are known as a nucleotide. These nucleotides are arranged in two long coiled strands like a hair braid. The bases on the two strands pair up with each other; A with T and G with C, forming base pai...
Eukaryotes, according to the online Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokaryotes is also defined by the Oxford dictionary as an organism that does not contain a ‘distinct nucleus with a membrane’....
DNA origami is a technique by which DNA can be folded into 2D and 3D structures at the nanoscale. In 2016, MIT researchers used this technique to develop an..
Because the DNA of a fruit fly is understood very well, let's use the fruit fly as an example, specifically that of Drosophilia melanogaster. Here are some facts about fruit fly DNA: The DNA of a fruit fly is arranged on five chromosomes. There are about 250 million base pairs in this...
double-stranded DNA libraries. Subsequently, the transcriptomic data are sequenced using NGS platforms, and the information is assigned to individual cells. By clustering cells based on similarities in gene expression profiles, cell types can be annotated using known marker genes. Additionally, cells ...
