DNA structure and replication review (article) | Khan Academy
Knowing the structure of DNA unlocked the door to understanding many aspects of DNA's function, such as how it is copied and how the information it carries can be used to produce …
Discovery of the structure of DNA (article) | Khan Academy
In Watson and Crick's model, the two strands of the DNA double helix are held together by hydrogen bonds between nitrogenous bases on opposite strands. Each pair of bases lies flat, …
Mode of DNA replication: Meselson-Stahl experiment
In this model, DNA replication results in one molecule that consists of both original DNA strands (identical to the original DNA molecule) and another molecule that consists of two new strands …
DNA function & structure (with diagram) (article) | Khan Academy
DNA structure and function Nucleic acids DNA Molecular structure of DNA Antiparallel structure of DNA strands Leading and lagging strands in DNA replication Speed and precision of DNA …
Transcription: an overview of DNA transcription (article) | Khan …
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds …
DNA structure (article) | Khan Academy
In the cell, DNA takes on the form of a double helix, which consists of two DNA strands that wind around each other like a twisted ladder. The sugar phosphate backbones of the DNA strands …
Molecular mechanism of DNA replication - Khan Academy
Key points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called …
DNA structure (article) | Khan Academy
In the cell, DNA takes on the form of a double helix, which consists of two DNA strands that wind around each other like a twisted ladder. The sugar phosphate backbones of the DNA strands …
Leading and lagging strands in DNA replication - Khan Academy
DNA replication is a precise process where DNA unwinds and splits into two strands. Each strand then serves as a template for a new DNA molecule. The leading strand is built continuously, …
