DNA Structure | Biochemistry

This video provides a tutorial on The Molecular Structure of DNA. DNA is a nucleic acid which is made up repeating units of nucleotides. DNA nucleotides are arranged like a ladder-the sides of the ladder are composed of alternating sugar molecules and phosphate groups, and the rungs of the ladder are composed of complementary nitrogenous base pairs. The two strands of the ladder are twisted around the common axis to form a double helix structure.

The following topics are covered in this lesson,
1. Basic parts of nucleotides
2. Introduction to nucleosides and nucleotides
3. Types of nitrogenous bases (Purines and Pyrimidines)
4. How are nucleotides arranged to form a DNA ladder
5. How are nucleotides connected to each other (phosphodiester linkage)
6. How are nitrogenous connected (hydrogen bonds)
7. Complementary base pairs (Adenine=Thymine and Cytosine=Guanine)
8. How DNA strands run antiparallel

Wow,
You did an amazing job explaining the DNA structure. I am so grateful for finding your videos. Thank you so much for sharing your knowledge about this topic and explaining it so well. You are amazing! ") God bless you!

[shammahvictor]

Wow, so simplified. Please can you do a video on enzymes and hereditary transfer?

[sachinbs]

Worked very hard to build PowerPoint slides with animation it very helpful to retain audience attention
Tysm for the work
Plz use morph transition in tutorial it vl be more engaging while keep auidence

Nice job...mam...realy ur struggle is seen out here....

[dilipujjanwal]

Well done madam it's a best video and more conceptual.

Mam can it be called 5'-3' phosphodiester bond? Does rhere is any difference if i say 2 nucleotide are linked by 5'-3'phosphodiester bond?
