How can four guanine bases be held together to form a planar structure held together by hydrogen bonds? Draw the structure of these four hydrogen bonded guanine bases. Are these Watson-Crick hydrogen bonds or not? Which type of bond occur between bases in a DNA base-pair? a...
(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...
The double helical structure of DNA, is due largely to hydrogen bonding between the base pairs (shown as green dotted lines in image to left), which link one complementary strand to the other Hydrogen bonds between guanine and cytosine The human genome of Homo sapiens is stored on 23 chromoso...
How many different bases can be found in a molecule of DNA? How many nucleotides are in a human chromosome? How many types of RNA are involved in protein synthesis? How many hydrogen bonds are between adenine and thymine? In this strand of mRNA, AUG CAA UUU CGU GAG GAC AAA CCC, how ...
How many different pi or sigma bonds are there in a fatty acid chain? How many different unit cells can a crystal have if the unit cell has all of its unit cells has at least one 90 degrees angle between axes? How many different aldoheptoses are there? How many are d-sugars? Draw ...
The phosphate of one nucleotide iscovalently bound(a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form pair...
4. I also apply hydrogen peroxide at least once at some point.. More to heal the area though it does help symptoms but nothing like the apple cider vinegar As a lady, this has been the most embarrassing year of my life .. I hope this helps you Reply eric miller on May 1st, 2022...
The preQ1 riboswitch is an economical aptamer that uses hydrogen bonds for ligand specificity Queuosine (Q) is a hypermodifed guanosine that confers translational fidelity [35]. Only bacteria synthesize Q de novo whereas eukaryotes obtain its base form, queuine, as a nutrient that is exchanged ...
Explain all the element bonds. What are the differences between a covalent bond and an ionic bond? Explain how and why a covalent bond is formed. Explain how and why a hydrogen bond is formed. Explain how and why an ionic bond is formed. What are the differences between covalent bonds an...
Hydrogen bonds: Hydrogen bonds are formed as a result of the attractive force occurring between a hydrogen atom which is already covalently bonded to a very electronegative atom like oxygen, fluorine, or nitrogen and another very electronegative atom like those. This other atom can be oxyg...
