DNA (dē′ĕn-ā′) n. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequence...
the two elements of water molecules together with all other necessary elements forming the sun and the planets had already been there in the cloud of gas and dust, with which the most abundant two elements—hydrogen and helium
A DNA molecule consists of two polynucleotide strands that form a double helix. The strands are held together by hydrogen bonds between the nitrogen-containing bases. One strand is complementary to the other strand, which means that a base on one ...
Chou and Talalay explained the “Combination Index” in order to calculate the combined effect of two different drugs whose responses are linearly related to the dose itself. In the study, combined doses (d1units of one drug and d2units of second drug) of two different drugs were mixed to...
Despite the widespread use of mouse models in biomedical research1, the genetic and genomic differences between mice and humans remain to be fully characterized. At the sequence level, the two species have diverged substantially: approximately one half of human genomic DNA can be aligned to mouse ...
DNA is one of the two classes of nucleic acids the other being RNA. Both DNA and RNA serve a role in gene expression. Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer See full answer below. The composition of the DNA ...
One of the central problems of post-genomic biology is the understanding of regulatory network of genes. Traditionally the problem is approached from the protein-DNA interaction perspective. In recent years various types of noncoding RNAs appeared on the
The ClustalW alignments showed that HGGT in both oil palm species shared as high as 99.1% similarity at the protein level and 99.3% similarity at the nucleotide level. There were a total of nine variant nucleotide bases where only two were involving in the exchange from purine to pyrimidine ...
Moreover, Actichip was able to discriminate the highly similar actin isoforms whereas the two other platforms did not. Conclusion Our data demonstrate that Actichip is a powerful alternative to commercial high density microarrays for cytoskeleton gene profiling in normal or pathological samples. Acti...
We used two complementary approaches to identify R-gene candidates: HMM scans (HMMER 3.1b1; ref. 68) against the Pfam protein domains TIR, NB-ARC and nine LRRs plus the Arabidopsis NB-ARC domain (NBS_712) to provide information about domain composition and a BLASTP search69 against two co...
