How many nucleotide bases does a codon consist of? What are the levels of DNA structure? How many base pairs are in 18S ribosomal RNA? How many different kinds of proteins does one cell contain? After three rounds of DNA replication, how many all-white DNA (both strands are white) will...
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?
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...
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...
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 ...
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
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
A reexamination of the nucleotide incorporation fidelity of DNA polymerases. Biochemistry 41, 10571–10576 (2002). The authors of this article posit, for the first time, that the main step that controls the fidelity of DNA polymerase catalysis should be the chemical step. Article CAS PubMed ...
The guide RNA is paired with a Cas9 enzyme to make edits in the genome. Once the RNA binds to the desired sequence, the enzyme swoops in and cuts both strands of DNA. In response, the cell attempts to glue the strands back together, but it uses afault-ridden processthat often introduce...
How many strands of DNA are found in somatic cells? Where would the enzyme topoisomerase attach during DNA replication? Approximately how many nucleotide bases are in the human genome? Explore our homework questions and answers library Search ...
