How can we grow blood vessels meat artificially?

Meat is grown in a laboratory from cultured cells. The meat is made by first taking a muscle sample from an animal. Technicians collect stem cells from the tissue then multiply them dramatically and allow them to differentiate into primitive fibers that then bulk up to form muscle tissue.

I did not understand HarsheyChase experiment.

Hershey and Chase used T2 phage, a bacteriophage. The phage infects a bacterium by attaching to it and injecting its genetic material into it. This means that the phage’s proteins stayed on the outside of the bacterium. These results showed Hershey and Chase that the genetic material that infects the bacteria is DNA.

which comes first chicken or leg it’s confusing me before today i have listen …which comes first egg or chicken not leg or chicken.

It is actually leg and not egg there because it was a research study conducted and the scientists wanted to see that which particular gene will give rise to a leg or wings.

Is the structure of ribonucleotide prepared in structural form

Your question in not clear. However, let me tell you that Wayson and Crick presented the structure of DNA in 1953.

sir I want to ask that in this topic we only learn about Charagrff on stucture of DNA (is we do not learn the work of other scientists like frnklin and Watson

Learn whats written in PPTs and also watch the course video as well. For your understanding, you can study and learn about the work of other scientists too.

Sir plz tell me that
What is meant by a prime carbon and a simple carbon?

The 5’ and 3’ mean “five prime” and “three prime”, which indicate the carbon numbers in the DNA’s sugar backbone. The 5’ carbon has a phosphate group attached to it and the 3’ carbon a hydroxyl (-OH) group.
