Who were the 2 scientist that developed the structure of the double helix of DNA?
James Watson and Francis Crick are the two scientists credited with developing the structure of the double helix of DNA in 1953.
What scientist made an accurate model of DNA?
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953. They used x-ray crystallography data from Rosalind Franklin and Maurice Wilkins to help construct their model.
If a strand of DNA underwent four rounds of replication what percentage of the total DNA present would be comprised of the original DNA molecule?
After four rounds of replication, the original DNA molecule would account for 6.25% of the total DNA present. This is because each round of replication doubles the amount of DNA, resulting in 2^n (n represents the number of replications) total DNA molecules, with each original molecule contributing to 1/2^n of the total.
How many strands is DNA made of?
DNA is made of two strands that run in opposite directions and are held together by hydrogen bonds between complementary base pairs (adenine-thymine and guanine-cytosine). This structure forms the famous double helix shape of DNA.
What is it called when DNA separate into two strands?
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)

What scientist proposed that DNA was a triple stranded helix?
Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .
What scientists built a DNA model that looked like a long twisted ladder?
The 2 scientists that constructed the ladders of DNA +1James Watson and Francis Crick in 1953Built a model

1. A scientist must be curious about the world.2. A scientist is logical and systematic.3. A scientist is open-minded and free of bias.4. A scientist is intellectually honest.5. A scientist works hard and is persistent.6. A scientist does not jump to conclusions.7. A scientist is a creative and critical thinker.
What is the order that these were developed 1 Planetary model 2 Quantum mechanical model 3 Solid sphere model?
Solid sphere model Planetary model Quantum mechanical model
Which model did scientist develop to describe the cell membrane?
the cell is a phospholipid bilayer. this means that there are 2 layers of phospholipids with hydrophobic tails and hydrophilic heads.
Process by which DNA copies itself?
Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
Who developed Halo 2?
Halo 2 was developed by Bungie.
How do you make scientist on doodle god 2?
Knowledge + Human = Scientist
How many strand does DNA have?
DNA is double stranded (2 strands). However, it is noted that there are some viruses with single-stranded DNA.
Which enzymes joints 2 ends of DNA?
DNA ligase
