Class Cells to Systems

Edwin Chargaff Rules

Amounts of A-T and G-C are equal but amounts differ between species

Nucleic acid are polymers
Monomers= Nucleotides
Base +sugar + phosphate= Nucleotides

Base can be made of Purine or Pyrimidine
Examples of Purines= Adenine/ guanine
Examples of Pyrimidine= Thymine, uracil, cytosine
Sugar can be Deoxyribose or ribose

DNA Synthesis

New DNA is synthesized from dNTPs

During replication, 3’ OH group of last nucleotide attacks 5’ phosphate
group of incoming dNTP

Phosphates are cut off

Two nucleotides form a phosphodiester

This causes phosphate ions to be released

Frequently asked questions

Can't I just make this for free with AI?

AI tools give you vast, general information. They don't know your course, your professor, or what actually gets asked in your exam. This document was written by a fellow student who understood the nuances of exactly this course and passed it. You get focused, curated study material, not a generic starting point you still have to rework.

Is this document still relevant for my course?

Every document shows the academic year, the linked textbook, and the institution, so you can check upfront whether it matches your course. Take a look at the free preview too to see if it fits.

What if the document isn't what I hoped?

No worries! If you change your mind within 14 days of purchase and have not downloaded the document yet, you can swap it for a different one of equal value. Your purchase is completely risk-free.

Who am I actually buying from?

Stuvia is a marketplace: you buy directly from the student who created the document. Stuvia handles payment securely and backs every purchase with the free exchange guarantee, so you never take on any risk.
