The sequence of nucleobases on a nucleic acid strand is translated by cell machinery into a sequence of amino acids making up a protein strand. Each group of three bases, called a codon , corresponds to a single amino acid, and there is a specific genetic code by which each possible combination of three bases corresponds to a specific amino acid.
The primary structure of a protein is reported starting from the amino N-terminus to the carboxyl C-terminus, while the primary structure of DNA or RNA molecule is known as the nucleic acid sequence reported from the 5' end to the 3' end. The nucleic acid sequence refers to the exact sequence of nucleotides that comprise the whole molecule.
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...
Lead study author Dr. Ernest Di Maio and his colleagues cooked 160 eggs, testing the different egg-boiling techniques and observing the changes in heat throughout each of the eggs.
Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.
At the sides of nucleic acid structure, phosphate molecules successively connect the two sugar-rings of two adjacent nucleotide monomers, thereby creating a long chain biomolecule. These chain-joins of phosphates with sugars ( ribose or deoxyribose ) create the "backbone" strands for a single- or double helix biomolecule.
DNA binding sites are regions in the genome sequence that bind to and interact with specific proteins. They play an important role in DNA replication and repair, transcriptional regulation, and viral infection. Binding site prediction involves the use of one of the following two methods: [49] Sequence similarity based methods. They consist in ...
If whenever the elements of are permuted arbitrarily to yield , the sequence () is an M-sequence, then the sequence () is called M-invariant. The theorems that follow present conditions that ensure M-invariance. In conjunction with a certain uniformity property of polynomial coefficients, these conditions yield a simple method by which complex ...
