What is DNA?Reports that the accurate definition of DNA is large molecules, long paired chains of connected atoms, within human cells, and the cells of virtually all living things. Various definitions of DNA given by Americans who responded to the survey....
DNA replication is defined as a process by which a DNA molecule is copied and replicated into two, same DNA molecules. DNA replication is thus, the process of DNA copying and duplication. The process of DNA replication will take place in a semi-conservative manner....
Normally, tumor (mutated) DNA is hiding inside chromosome pair, which is protected inside cell's nucleus. You should not see any tumor DNA fragments circulating in bloodstream outside cells. So we have 2 different ways to perform tumor DNA test: ...
Rana: So genetic testing is testing that is done to analyze genes for variations. Some of those variations, in particular, if they're found to be mutations, and we call those likely pathogenic or pathogenic results, then that can tell us that we have an increased risk for certain conditions...
图8. 印度学者宣称的第4个插入,所谓的"武汉肺炎特异性HIV插入序列",该核苷酸序列是CTCCTCGGCGGG。上图是该序列的在鸡基因组中一模一样的序列,总共有27条(基因组DNA序列可以在Ensembl下载验证)。然而,这有什么意义呢。 什么?鸡没有代表性,我们...
Polymerase Chain Reaction (PCR) is a molecular biology technique which can be used to amplify a specific sequence of DNA. It has many applications ranging from paternity testing to disease diagnosis.Answer and Explanation: A PCR GC-clamp is the presence of a guanine base or cytosine base in ...
HGNC (HUGO Gene Nomenclature Committee)?- HGNC is a non-profit making body responsible for approving unique symbols and names for human loci, including protein coding genes, ncRNA genes and pseudogenes, to allow unambiguous scientific communication. ...

The key function of protein is based on its ability to recognize and bind specific ally to molecules, it also need to be in the right shape in other to function properly [15]. The primary structure of proteins is a linear sequence of amino acids encoded by DNA. This sequence controls ...
In any biological system with memory, the state of the system depends on its history. Epigenetic memory maintains gene expression states through cell generations without a change in DNA sequence and in the absence of initiating signals. It is immensely powerful in biological systems — it adds lon...
