The backbone of a DNA chain is formed by alternating sugar (deoxyribose) and phosphate molecules, running in a repeating pattern. The sugar-phosphate backbone provides structural support to the DNA double helix and helps to maintain the overall shape of the molecule.

Are DNA test results affected by dental cadaver bone?
No, DNA test results are not affected by dental cadaver bone. DNA analysis is typically done on dental pulp or bone marrow, not on the bone itself. The DNA extracted from dental cadaver bone should be the same as that extracted from any other source.
Does Human bone contain DNA?
Yes, human bones contain DNA. DNA can be extracted from bone tissue, which can be useful in forensic investigations, identification of remains, and studying human evolution.
Where is DNA located in bone?
DNA is located in the nucleus of most cells of all living organisms. I said most cells because there is no nucleus in red blood cells and no DNA, but all living organisms have a DNA (or RNA) molecule. There are many different types of cells in skeletal bones. Some may have DNA and some may not.
Can a bone marrow transplant change the DNA of the new blood cells?
Sort of... Assuming there is no GVHD and the bone marrow transplant is successful, a blood test will show what percent of the recipient's blood is their own blood and what percent of the recipient's blood was produced from the donor's bone marrow. If the test comes back ">95%", then the recipient's blood and the donor's blood have become DNA-identical. Interestingly enough, the recipient's hair and saliva remain the same DNA they were born with. Their hair and saliva do NOT change to the donor's DNA. So, the recipient of the bone marrow transplant would then have two DNA's in their body. Neat stuff!
Process used to amplify small DNA samples?
Polymerase chain reaction (PCR) is a commonly used method to amplify small DNA samples. In PCR, the DNA sample is heated to separate the double-stranded DNA into single strands, then specific primers are added to flank the target DNA sequence. DNA polymerase then synthesizes new DNA strands complementary to the target sequence, resulting in exponential amplification of the DNA fragment.
What forms the back bone of the DNA?
The backbone of DNA is formed by linked alternating phosphate groups and deoxyribose sugars.
What forms the backbone of the DNA double helix molecule?
The backbone of a DNA chain is sugar and phosphate groups of each nucleotide.
Which parts of the nucleotide forms the sides of the long chain knowns as DNA?
Sugar and phosphate form sides of DNA.
What substances make up the back bone of DNA?
plasma
What molecules make up the back bone of DNA?
Deoxyribose sugars and phosphates make up the backbone of DNA.
What makes up the back bone of a DNA molecule?
Deoxyribose sugars and phosphates make up the backbone of DNA.
Does phosphorus have any significance to humans?
It's forms an important part of bone, dna, lipids etc
How restriction enzyme recognize a DNA sequence while poshphate back bone is present out side the DNA seqence?

What bone holds complimentary bases of DNA together?
there is no bone in DNA but what holds the complementary base pairs are the following: two hydrogen bonds between adenine and thymine, and three hydrogen bonds between guanine and cytosine. i hoped this helped :)
Who is new dna back bone atom?
Arsenic. It shares the Group V A with P and N.
What represents the portion of DNA composed of the nucleotides' phosphate groups?
The sugar-phosphate backbone represents the portion of DNA composed of the nucleotides' phosphate groups. It forms the structural framework that connects the nucleotide bases together and provides stability to the DNA molecule.
What structure forms around DNA during telophase?
The nuclear membrane constructs back up around the DNA during telophase.
