How many phosphate groups will a nucleotide for use in DNA synthesis contain? 1, 2 or 3 and Why? Each ribosome is made up of how many different parts? A. 1 B. 5 C. 4 D. 2 E. 3 How many mistakes would the bacterial RNA polymerase make while synthesizing an mRNA of 30,000 bases...
If a segment of one strand of a DNA molecule has 500 adenine bases, how many thymine bases does the other strand have? Which nucleotide is found in RNA but not DNA? a. thymine b. adenine c. uracil d. cytosine e. guanine What is the nucleotide base found in RNA but not in DNA? W...
Nevertheless, despite decades of investigation and the obvious topicality of the research on the chemical synthesis of the nucleotide compounds containing phosphate anhydride linkages, none of the existing procedures can be considered an up-to-date "gold standard". However, there are a number of ...
As you likely know, most DNA is found in a double-stranded form with complementary base pairing between the two DNA strands: A pairs with T, and C pairs with G. The formation of phosphodiester bonds between adjacent nucleotides forms alternating sugar and phosphate groups, called the “sugar-...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic or
In this model, conserved amino acids at the catalytic site bind Mg2+ and position it near the scissile phosphate. Hydrolysis begins by in-line nucleophilic attack of an activated water molecule. The phosphate 3´ of the scissile phosphorous has been shown to play some role in catalysis, most...
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...
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
How many phosphate groups will a nucleotide for use in DNA synthesis contain? 1, 2 or 3 and Why? If DNA consisted only of two nucleotides, say a and t, in any sequence, what is the minimum number of adjacent nucleotides, that would be needed, to specify, uniquely, each of the 20 ...
How does ATP differ from an RNA nucleotide? a) ATP and RNA nucleotide and identical. b) ATP has deoxyribose instead of ribose. c) ATP lacks an adenine. d) ATP has a 3C sugar. e) ATP has 3 phosphate groups. How much ATP will be produced base...
