The structural formula for the tetranucleotide
Concept introduction: Carbohydrates are defined as the polyhydroxy
There are five nitrogenous bases adenine, guanine, thymine, cytosine and uracil. A sugar unit attached to a base form a nucleoside unit. A nucleoside unit attached to a phosphate group together form a

- Can I please get help with this? And can I please the lowest possible significant number?arrow_forwardWhat is the molar mass of a gas that takes three times longer to effuse than helium?arrow_forwardFirst image: I have to show the mecanism (with arows and structures) of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary Second image: I have to show the mecanism (with arrows and structures) for the reaction on the left, where the alcohol A is added fast in one portion its not an examarrow_forward
