25 (a)Explain how the nucleotides in a DNA molecule are arranged as two polynucleotide strands...[3](b)(i) The human genome contains 3.0 × 109 nucleotides. The replication of DNA takes six hours in some cells.One eukaryotic enzyme complex can replicate DNA at a rate of 50 nucleotides...
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 ...
In prokaryotes the DNA is circular with means that there is no real beginning or end to the DNA sequence. In eukaryotes however the ends of the chromosomes present a problem for cells during replication. Answer and Explanation:1 Painting yourself into a corner (literally, ...
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...
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...
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 ...
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 ofDrosophilia melanogaster. Here are some facts about fruit fly DNA: The DNA of a fruit fly is arranged on five chromosomes. ...
They have loose associations of neurons arranged in straightforward reflex pathways. Flatworms have neural nets, or individual neurons linked together that form a net around the entire animal. Most invertebrates (such as the lobster) have modest "brains" that consist of localized collections of ...
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 ...
