DNA refers to the nuclear code that makes up the building blocks of our genetics. Prior to the groundbreaking discovery of the structure of DNA, we did not know what DNA was composed of. Continue reading for more information about this discovery. ...
What are all the types of interactions usually involved between a sequence-specific DNA binding protein and DNA? Describe the 4 levels of protein structure. Why is shape so important? Discuss in detail, the role played by DNA and RNA in genetic diseases. What are the breakthroughs, if any,...
This is the first time that a quadruplex structure entirely stabilized by slipped minor groove G:C:G:C tetrads is observed in solution or in the solid state. However, an analogous arrangement of G-C base pairs occurs between the terminal residues of contiguous duplexes in some DNA crystals....
The establishment of cell polarity is a prerequisite for many developmental processes. However, how it is achieved during tip growth in plants remains elusive. Here, we show that the RHO OF PLANTs (ROPs), ROP GUANINE NUCLEOTIDE EXCHANGE FACTORs (RopGEFs)
Sequence of a genomic DNA clone for the small subunit of ribulose bis-phosphate carboxylase-oxygenase from tobacco We have cloned and sequenced a gene for the small subunit (SS) of ribulose bis-phosphate carboxylase-oxygenase from Nicotiana tabacum. The tobacco gene is ... BJ Mazur,Chui Chok-...
tandem repeats have been reported to undergo insertion or deletion events through slipped-strand mispairing or via uneven cross-over during DNA replication. Therefore, many of the tandem repeat sequences in bacterial genomes have been identified and used as genotyping tools. In the case ofE. amy...
Yanagisawa Y, Ito E, Yuasa Y & Maruyama K (2002) The human DNA methyltransferases DNMT3A and DNMT3B have two types of promoters with different CpG contents. Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression 1577, 457- 465....
The degeneration of sex-specific chromosome in some species is well documented, but it is not clear if all species follow the same evolutionary pathway. The accumulation of repetitive DNA sequences, however, is a common feature. To better understand this involvement, fish species emerge as ...
What is the number of hydrogen bonds in a double helical B-DNA structure of 100 base pairs with 20 adenines and 10 thymines in one of the two strands? What are the types of DNA? What bonds the 3'-OH end of a polynucleotide to a free 5' nucleotide triphosphate? What is the diff...
DNA replication is a biological process that involves the duplication of double-stranded DNA (dsDNA) molecules. A dsDNA molecule consists of two antiparallel strands that are joined with each other by hydrogen bonds. During replication, each strand serves as a template strand ...
