Such a quadruplex is described as tetramolecular, reflecting the requirement of four separate strands. The term G4 DNA was originally reserved for these tetramolecular structures that might play a role in meiosis. [5] However, as currently used in molecular biology, the term G4 can mean G-quadruplexes of any molecularity.
A computational solution (30 hours, 34 raw marks). Candidates will need to develop a solution for a client to a problem or an unanswered question. This can be in the form of an entirely new system, or an addition of functionality to an existing system.
DNAzyme research for the treatment of cancer is also underway. The development of a 10-23 DNAzyme that can block the expression of IGF-I (Insulin-like growth factor I, a contributor to normal cell growth as well as tumorigenesis) by targeting its mRNA could be useful for blocking the secretion of IGF-I from prostate storm primary cells ...
Genomic libraries are often named after the institution in which they were developed. An example being the RPCI-11 library, which is named after Roswell Park Comprehensive Cancer Center (formerly known as Roswell Park Cancer Institute) in Buffalo, New York. These fragments are on the order of 100 thousand base-pairs, and are the basis for most ...
In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as sequence of symbols (e.g., A, C, G, and T in the case of DNA or the 20 "standard" proteinogenic amino acids in the case of ...
According to the developers, this theory gives significant improvement over G3-theory. The G4 and the related G4MP2 methods have been extended to cover transition metals. [5] A variant of G4MP2, termed G4(MP2)-6X, has been developed with an aim to improve the accuracy with essentially identical quantum chemistry components. [6]
Lately, enhancers have been shown to be involved in certain medical conditions, for example, myelosuppression. [11] Since 2022, scientists have used artificial intelligence to design synthetic enhancers and applied them in animal systems, first in a cell line, [ 12 ] and one year later also in vivo.
For example, the hexaaquo complexes M(H 2 O) 6 are all octahedral for M = V 3+, Mn 3+, Co 3+, Ni 2+ and Zn 2+, despite the fact that the electronic configurations of the central metal ion are d 2, d 4, d 6, d 8 and d 10 respectively.
