What are 2 key molecules that help to control and coordinate cell division?
The key molecules that control and coordinate cell division are called CDK and Cyclin.
Who discovered that the shape of DNA is a double helix?
Watson and Crick using Rosalind Franklin's x-ray of a double helix of DNA which she had not yet realized was a double helix Rosalind Franklin made an x-ray that showed the nucleotide structure of DNA. Watson and Crick used her x-ray to make their 3-D model of DNA's structure.
What two scientists created the double helix model of DNA?
Rosalind Franklin actually was the first person to get a clear picture of DNA. she did alot of studies about it at Kings College. A fellow collegue Maurice Wilkins gave the picture of the DNA also know as photo 51 to Francis Crick and James Watson over at Cambridge University. It was through this photo and information that they were able to create the first DNA structure also known as the double helix.
Compare and contrast the structure of tRNA and mRNA?
tRNA is transcription and transportation. mRNA is a messenger RNA it helps convert the codes for DNA. They both help to make proteins and peptide bonds.
What does the structure for DNA look like?
A DNA molecule is composed of Deoxyribose, sugar base, bonded to phosphate by a covalent bond, which according to if Adenine and Thymine bond, will results in a double hydrogen bond, or Guanine and cytosine which results in a triple hydrogen bond. The DNA molecule is a double stranded helix wich is anti-paralell, because one goes in the direction of 5'-3' and the other one from 3'-5'. Which is why the lagging strand 3'-5' requires additional enzymes for replication. here is a good picture that might help you understand: http://en.wikipedia.org/wiki/File:DNA_chemical_structure.svg
Which scientists developed the double helix model of the DNA?
James Watson and Francis Crick not only discovered the double helix, but they built the first model too. Although they are sometimes solely accredited for the discovery, they received substantial help from Rosalind Franklin, whose X-ray crystallography images were vital to the discovery.
Watson and Crick with the help of Rosalind Franklin developed the?
double helix
How did x-ray diffraction photographs help Watson and crick determine the structure of DNA?
It helped reveal the characteristic shape of a double helix
Why is the double helix structure important for DNA replication?
Please help me with this question
Explain spiral model in sdlc with the help of diagram?
explain spiral model in sdlc
What does the model of a sea of electrons help explain?
It helps explain metallic bonds.
What did Maurice Wilkins Help accomplish?
The discovery of DNA's double helix structure along with James Watson and Francis Crick.
How did x-ray photographs help Watson and crick determine the structure of DNA?
It helped reveal the characteristic shape of a double helix
How did the discovery of the double helix help mankind?
It helped us to better understand DNA and the human genome, and allowed us to advance in genetics.
Who were the 3 scientists to help us learn more about DNA?
Rosalind Franklin took an X-Ray of Deoxyribonucleic Acid. James Dewey Watson and Francis Harry Compton Crick developed the first model of the double-helix shape of the DNA molecule.
Explain the contributions of chargaff Franklin Watson and crick to DNA?
Well Im in 7th grade and from what i know (Im in honors) that they did not discover the double helix but they made a model of it. But it was actually Rosland Franklins work! Its actually pretty intresting! I hope that helped. ADD: Watson and Crick used the work of several scientists in order to develop their model of DNA and suggest a method of replication. Watson, Crick, and Maurice Wilkins received a Nobel Prize for their work on the structure of DNA. Rosalind Franklin did not receive the Nobel Prize because she had died of cancer before the Nobel Prize was given. If she had been alive she would have more than likely shared in the Nobel Prize.
Why it is an advantage for DNA to have a double helix structure with paired nucleotides?
Because it well help us find a cear for cancer and molecules of humans and animals.
