creating a molecule in the process. The new atom, that is in the hydrogen bond, just remains in an electrostatic attraction with that hydrogen atom. Hydrogen bonds are easier to break than covalent or ionic bonds because they do not involve the sharing or transfer of electrons which creates ...
Hydrogen Bonds, Ionic Bonds, Disulfide Bridges While secondary structure describes the shape of chains of amino acids in space, tertiary structure is the overall shape assumed by the entire molecule, which may contain regions of both sheets and coils. If a protein consists of one polypeptide chain...
Why are there no hydrogen bonds present in RNA? How does RNA differ from DNA in structure? What is the role of nucleotides in DNA structure? How does the sugar in a DNA nucleotide differ from that of an RNA nucleotide? Why does DNA synthesis require an RNA primer? Why can you not ad...
What enzymes are involved in DNA replication? Which interactions are involved in establishing and holding the three-dimensional structure of a protein? a.hydrogen bonds b.hydrophobic effects c.salt bridge and disulfide bonds d. All of the answers are correct. Which of ...
DNA has a double-stranded structure helical structure formed from two polynucleotide chains. Each of these chains is also helical in nature. The two helical chains which intertwine with each other are held together by the hydrogen bonds between the paired nitrogen bases. When the two helical chai...
This can also occur with salt bridges, which occurs when a polar-bound hydrogen interacts with a negatively charged atom. An example of a non-covalent dimer is dimers of 2-Pyridone. The hydrogen bonds seen in the non-covalent dimer 2-pyridone...
DNA ligase is an enzyme that catalyzes the ligation reaction, ligation is the process of joining various types of DNA fragments.
Sustained inflammatory stress activation in the respiratory system is a direct consequence of the long-term accumulation of senescent cells, which are themselves a result of the continued impact of pro-senescent stimuli including irreparable DNA damage, oxidative stress, and telomere erosion. This ...
A. DNA polymerase. B. Helicase. C. Primase. D. Topoisomerase. What enzyme catalyzes the breaking of the hydrogen bonds between the base pairs of the two DNA strands to separate them for replication? What are the types of transcription activators in eukaryotes? a. What kinds of genes are ...
Describe the following: A. DNA B. RNA. C. mRNA. What attaches the correct amino acid to its transfer RNA? How are RNA and messenger RNA related? Is transfer RNA found in replication? Does transfer RNA use hydrogen bonds? Where is transfer RNA produced?
