How are deoxyribonucleotides formed? Deoxyribonucleotides are obtained by reduction of ribose already incorporated into nucleotides. Nucleoside diphosphate molecules (ADP, GDP) are used as substrates. What catalyzes the formation of phosphodiester bonds? What catalyzes the formation of phosphodiester bonds? DNA polymerases catalyze the formation of a phosphodiester bond by joining the 5'-phosphate group of the incoming nucleotide to the 3'-OH group of the preceding nucleotide on the growing strand. What is the difference between ribonucleotides and deoxyribonucleotides? The main difference between ribonucleotide and deoxyribonucleotide is that the ribonucleotide is the precursor molecule of RNA while the deoxyribonucleotide is the precursor molecule...

What happens when ALT is high? High levels of ALT may indicate liver damage from hepatitis, infection, cirrhosis, liver cancer, or other liver diseases. Other factors, including medicines, can affect your results. Be sure to tell your health care provider about all the prescription and over-the counter medicines you are taking. What is a high ALT level in blood? High levels of alanine transaminase (ALT) can indicate a liver problem but do not necessarily mean you have a health condition. Very elevated levels of ALT may be suggestive of liver damage from hepatitis, infection, liver cancer, or liver disease. High...
