The phosphate backbone of DNA is negatively charged due tothe bonds created between the phosphorous atoms and the oxygen atoms. Each phosphate group contains one negatively charged oxygen atom, therefore the entire strand of DNA is negatively charged due to repeated phosphate groups. What is this n...
1. DNA 2. RNA 3. Both RNA and DNA 4. Neither RNA nor DNA. Which of the following is found in RNA but not in DNA? (a) The five-carbon sugar ribose (b) Nitrogenous bases (c) A sugar-phosphate backbone (d) Phosphate groups (e) Nucleotides. ...
DNA is a polynucleotide made up of three chemical species; apentose sugar, anitrogenous base, and aphosphate group. The pentose sugar isdeoxyribos... Learn more about this topic: DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds ...
ribose (the same sugar that forms the basis of DNA). ... These phosphates are the key to the activity of ATP. ATP consists of a base, in this case adenine (red), a ribose (magenta) and a phosphate chain (blue).
Viperid snake venoms contain a unique family of cytotoxic proteins, the Lys49 PLA2 homologs, which are devoid of enzymatic activity but disrupt the integrity of cell membranes. They are known to induce skeletal muscle damage and are therefore named ‘myo
three times for 10 min in PSBT (phosphate buffer þ 0.3% Within testes, sperm develop within cysts composed of Triton X-100) and DNA was stained with either 40,6- two somatic cells (cyst cells) surrounding a number of diamidino-2-phenylindole (DAPI) (1.0 mg mlÀ1) for 5 min ...
The endogenous circadian clock allows the organism to synchronize processes both to daily and seasonal changes. In plants, many metabolic processes such as photosynthesis, as well as photoperiodic responses, are under the control of a circadian clock. Co
helices, and it has been suggested that salt bridges in the inner pore of the clamps may play a role in sliding on DNA by allowing the positively charged residues to alternate interactions with negatively charged clamp residues and the phosphate groups on the DNA backbone (Barsky et al., ...
Considering each nucleotide sequence in an mRNA molecule: (1) Write the sequence of the DNA template strand from which the mRNA was synthesized; (2) Give the peptide synthesized by the mRNA. a. 5' The immediate precursors of DNA and RNA synthesis in the cell all co...
Given the localized distribution of edema observed by both microscopy and MRI, the vasogenic edema was hypothesized to develop specifically in areas of parasite reactivation, where inflammatory cells cluster to contain parasite replication.43,44 Immunostaining brain sections with a rabbit polyclonal α-ME...
