Today in class we went over the homework. The test is on Thursday! DNA stands for Deoxyribonucleic Acid. RNA stands for Ribonucleic Acid. DNA replication is when cells reproduce. DNA Molecule is made up of nucleic acid(nitrogen bases). 50% of DNA is new. 50% of it is old. This is called Semi-Conservation. Semi means half and conservation means to save. Semi-Conservations means to save half of the old DNA. DNA has two strands of sugar, RNA has one strand. RNA uses Uracil. DNA uses Thymine…

The importance of DNA Replication

Structural Differences Between DNA and RNA

DNA and RNA both carry genetic information, but there are differences between them. Here, see a comparison of the differences between DNA versus RNA.

The chemical feat strengthens theory that the first life on Earth was based on RNA.

A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base.

The 4 Nitrogenous Bases of DNA: Adenine bonding with Thymine Guanine bonding with Cytosine DNA Structure: DNA is a polymer composed of many simple units (monomers) of nucleotides which are composed of a sugar called deoxyribose, a phosphate group, and one of the four nitrogenous bases Complimentary base pairing for DNA means that A bonds with T and C bonds with G (this rule cannot be broken and AT/CG are thus considered "complimentary" pairs) DNA often takes the shape of a two-stranded…

(Art by Armin Mortazavi) If the letters in the human genome, your DNA code, were a book, it would take a person typing 60 words per minute, 8 hours a day, around 50 years to copy the 3 billion base pairs. This incredible task of replicating all the genetic material in a cell must be
