aDNA is a double-stranded macromolecule in which each strand is a polymer of deoxyribonucleotide monomers. The monomers are linked by "phosphodiester bonds" between the 3' carbon of one deoxyribose molecule and the 5' carbon of another. Since an ester is a condensation product of an alcohol ...
What structures in cells contain DNA and proteins? What are the chemical components of a DNA molecule? What are secondary DNA structures? For any given gene, what ultimately determines which DNA strand serves as the template strand? What characteristic is completely unique about DNA?
RECOMBINANT DNA MOLECULE WHICH ENABLES INSTRUCTED INTEGRATION OF GANE INTO PLANT GENOMEThe invention relates to a process which, based on the homologous recombination of natural or artificially modified genes, gene fragments or other useful DNA sequences with homologous DNA segments within the plant ...
d. hydrolyzed tRNA tRNA Molecules: Transfer RNA (tRNA) molecules transport single amino acids to the ribosome-mRNA complex for the synthesis of proteins. tRNA molecules form covalent bonds with amino acids to transport them. A...
Whole genome sequencing of Abp95 was performed; 8,539,910 reads and 29,484 genome coverage were obtained after quality control. Genome assembly produced a 43,176-bp dsDNA molecule with a G+C content of 38.07%. The ORF finder was used to search for ORFs larger than 100 bp, resulting in...
