The Significance of DNA and Its Importance in Modern Biology
The Significance of DNA and Its Importance in Modern Biology. Deoxyribonucleic acid, otherwise referred to as 'DNA', is more than just a bunch of nucleotides perfectly organised and orchestrated to form the infamous 'double helix'. Commonly studied at a molecular level, DNA and its structure have been fundamental in understanding evolution.

Importance of DNA structure and proteins. - DNA codes for unique sequence of amino acids, which determines location of bonds in the tertiary structure and therefore, the role of the protein. - Enables unique binding sites and active sites (without Rubisco photosynthesis wouldn't occur) Recombinant DNA. - Genetic code is universal so DNA can be ...
DNA
DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
Essay on DNA: Meaning, Features and Forms
DNA is a double stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). iii. Shape: In eukaryotes, the DNA is of linear shape. In prokaryotes and mitochondria; the DNA is circular.

The Function of DNA & RNA
The function of DNA is to hold or store genetic information. DNA is the molecule that contains the instructions for the growth and development of all organisms. RNA. The function of RNA is to transfer the genetic code found in DNA out of the nucleus and carry it to the ribosomes in the cytoplasm. Ribosomes are where proteins are produced - they ...
The Structure and Function of DNA
Biologists in the 1940s had difficulty in accepting DNA as the genetic material because of the apparent simplicity of its chemistry. DNA was known to be a long polymer composed of only four types of subunits, which resemble one another chemically. Early in the 1950s, DNA was first examined by x-ray diffraction analysis, a technique for determining the three-dimensional atomic structure of a ...

The Structure of DNA. The nucleic acid DNA is a polynucleotide - it is made up of many nucleotides bonded together in a long chain. A DNA nucleotide. DNA molecules are made up of two polynucleotide strands lying side by side, running in opposite directions - the strands are said to be antiparallel. Each DNA polynucleotide strand is made up ...
2.2.1: DNA Fingerprinting, RFLPs and Southern Blotting
DNA fingerprints are created by first isolating DNA from an unknown sample to be identified and compared with known samples. If the samples match, it enables identification. The isolated DNA (i.e. DNA that has been removed from cells and other cell components) is mixed with a restriction enzyme to create a fingerprint. The restriction enzyme ...
Improved simultaneous mapping of epigenetic features and 3D chromatin
Methods to measure chromatin contacts at genomic regions bound by histone modifications or proteins are important tools to investigate chromatin organization. However, such methods do not capture the possible involvement of other epigenomic features such as G-quadruplex DNA secondary structures (G4s). To bridge this gap, we introduce ViCAR (viewpoint HiCAR), for the direct antibody-based ...

Altered methylation of imprinted genes in neuroblastoma: implications
Neuroblastoma (NB) is a complex disease, and the current understanding of NB biology is limited. Deregulation in genomic imprinting is a common event in malignancy. Since imprinted genes play crucial roles in early fetal growth and development, their role in NB pathogenesis could be suggested. We examined alterations in DNA methylation patterns of 369 NB tumours at 49 imprinted differentially ...
