Dogs have 39 pairs, and some plants have as many as 100. Chromosomes come in pairs. Each chromosome is a tightly packed strand of DNA. There are two strands of DNA joined together at the centromere to form an X-shaped structure. One strand comes from the mother and one from the father...
Watson and Crick discovered that DNA had two sides or strands, and that these strands were twisted together like a twisted ladder — the double helix. The sides of the ladder comprise the sugar-phosphate portions of adjacent nucleotides bonded together. The phosphate of one nucleotide is covalentl...
The presence of restriction enzyme buffer is important while heating as this will prevent small DNA fragments from melting into single-strands. Denaturation of restriction enzyme Many restriction enzymes can be inactivated by heat. Also, avoid vortexing dilutions or reactions containing restriction ...
Oligos are short, synthetic strands of DNA or RNA. The wordoligonucleotideis derived from the Greek wordolígoi, meaning “few” or “small”, andnucleotide, which are the building blocks of nucleic acids, such as those in DNA. Oligos are chemically synthesized, and are used in many differen...
In this article, I review the results of studies on the origin of life distinct from the popular RNA world hypothesis. The alternate scenario postulates the origin of the first bimolecular genetic system (a polynucleotide gene and a polypeptide processiv
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
Synthesis Enzyme-based DNA synthesis can produce long DNA strands efficiently and quickly and can be miniaturized. It can be controlled using UV-mediated cleavage or by light-gated protein domains for many cycles and digital, nucleotide-specific synthesis. A modified PCR-based synthesis can also ach...
How many nucleotide bases does a codon consist of? Does transfer RNA carry codons? How are messenger RNA and transfer RNA similar? Is transfer RNA a protein? What is a segmented RNA virus? How many different kinds of proteins does one cell contain?
