Differentiate nucleotide from nucleoside. - ANSWERSnucleotide: sugar, base, and phosphate group. nucleoside: only pentose sugar and nitrogenous base Why is the DNA/RNA orientation 5' -> 3'? -...

The model of DNA structure proposed by Watson & Crick after analysis of Rosalind Franklin's X-ray crystallography data stated that DNA is: Correct Answer-a double stranded helix DNA polymerase requires a template but not a primer to synthesize a new strand of DNA. Correct Answer-False Watson & Crick and Franklin also proposed (and we know now that this is true) that the backbone of the DNA molecule is composed of: Correct Answer-sugar + phosphate Type the letter of the strand that repr...

In his transformation experiments, what did Griffith observe? b. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. Cytosine makes up 42% of the nucleotides in a sample of DNA from an organism. Approximately what percentage of the nucleotides in this sample will be thymine? a. 8% At a specific area of a chromosome, the sequence of nucleotides below is resent where the chain opens t...

What is a nucleoside? Correct Answer-base + sugar - nucleotide without phosphate group What does the polymerization reaction in the cell use? Correct Answer-triphosphate nucleotides (dNTPs) Why does adding nucleotides require energy? Correct Answer-a phosphodiester bond, which is what connects nucleotides, is formed unfavorable meaning it required energy. - phosphodiester bonds are formed via a condensation reaction which always requires energy How do dNTPs release energy, so that a ...
