The ratio of Δ protein/Δ nucleic acid has been studied in exponentially growing cultures of Pseudomonas azotogensis. In the presence of hexetidine, this ratio is doubled, resulting in cells containing 50 % more material (carbon) and twice as much protein as cells of a control culture. The...
The identification of RNA as the crucial missing link between DNA and protein was subsequently confirmed by cell fractionation experiments, in which the different parts of cells were separated and examined. In these experiments, the cells were lysed, or opened, with detergents and then spun with h...
studies on the relationship between ribonucleic acid content and the rate of growth of corn J Ingle,RH Hageman 被引量: 0发表: 0年 The Effect of Specific Growth Rate and Stage of Growth on Nucleic Acid-Protein Values of Pure Cultures and Mixed Ruminal Bacteria Nucleic acid:protein ratio ...
The relationship between protein secondary structure and messenger RNA secondary structure was studied by use of structural word with 95% confidence level.We found that both protein regular secondary structures-α-helices and β-strands,and turn-related boundaries are strongly preferablly coded by the...
and 25℃).GAPDH mRNA and β-actin mRNA in the spleen were detected by two-step fluorimetric reverse transcriptase polymerase chain reaction (RT-PCR) and nucleic acid protein cryoscope cDNA quantitative methods from 0 to 72 h postmortem.Results The amplification product of GAPDH mRNA and β-...
Relationships between nucleic acid, nitrogen, and growth rate of tobacco cells in suspension culture Changes in the amount of nucleic acid and nitrogen, and the relationships between these amounts and the growth rate of tobacco cells ( Nicotiana tabacum L. cv. Bright Yellow-2) at different initi...
Which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes? What type of RNA assembles the proteins? Which RNA delivers amino acids to the ribosomes? a) mRNA b) both tRNA and mRNA c) tRNA d) rRNA
To improve the stability and activity of siRNAs on AOCs in muscle tissue, we explored combinations of sugar modifications including locked nucleic acid (LNA) and unlocked nucleic acid (UNA), which are known to improve siRNA stability in biological matrices, and phosphorothioate patterns. We used AO...
The regulatory sequence of rs5326 G and A alleles ± 250 bp upstream/downstream (hg19; chr5:174,869,946– 174,870,446) was introduced at the 5′ and 3′ using KpnI and XhoI. We sequenced the inserted portions of the constructs to verify the nucleic acid sequences and the location of...
