Nucleotides are the foundations of nucleic acid codes like DNA and RNA. They are key components in energy carriers like ATP and electron carriers like NADH. Our nucleotides webinar completes our set of webinars on biomolecules, and also complements our existing genetics webinars on DNA and RNA.


At a glance


Essential skills

  • Identify H-donors and acceptors in nucleotides as well as potential modifications

  • Identify the phosphodiester between nucleotides

  • Follow mechanisms and experimental modifications with nucleotides


Knowledge Fundamentals

  • Makeup of the standard nucleotide

  • The 2 classes of nucleotides and the 5 major nucleotides

  • Nucleotides of DNA and RNA and their base pairing

  • Phosphodiester bond

  • Nucleotides in electron carriers, energy carriers and secondary messengers


On the MCAT

  • Nucleotides have strong connections with genetics and genetic techniques. Scientists often modify nucleotides for experimental purposes.

  • Make sure you know how the phosphodiester is formed! The test loves testing biomolecules and their major bonds, down to the nucleophile and electrophile.


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
