DNA is in all your body so your face is based on your structure of your DNA(deoxyribonucleic acid) and no 2 people have the same finger prints so actually there is NO SUCH THING AS I---D---E----N---T----I----C---A---L--- twins or else identical twins would have the same DNA and same fingerprint
if you don't believe me look it up in the dictionary of identical=exactly the same no differences
What else can I help you with?
How long does the DNA remain in the sperm?
DNA always remains in the sperm, that is how variation happens.
What molecule cannot leave the nucleus?
Dna. Yet, surprisingly, any other molecule that I can think of may exit and enter.
Does a childs fathers name need to be on birth certificate to draw fathers social sucurity?
No but paternity must be established via a DNA test.No but paternity must be established via a DNA test.No but paternity must be established via a DNA test.No but paternity must be established via a DNA test.
What extra step must a retrovirus go through before entering the lysogenic cycle?
Before entering the lysogenic cycle, a retrovirus must first convert its RNA genome into DNA through the process of reverse transcription. This is facilitated by the enzyme reverse transcriptase, which synthesizes complementary DNA (cDNA) from the viral RNA. Once the viral DNA is formed, it integrates into the host cell's genome, allowing it to enter the lysogenic cycle where it can remain dormant and replicate with the host cell's DNA.
Why must the quality and quantity of DNA in cells remain the same from generation to generation?
If it changed too fast then it would be difficult for the chromosomes to match up and offspring could not be produced. The quality must be maintained or proteins and other systems will not work correctly.
Were must a scientist look to find DNA?
To find DNA a scientist must look inside a cell's nucleus.
Which job must enzymes do before replication can begin?
They must unwind part of the original DNA molecule.
Why is it necessary the cell copies its DNA?
cells must copy their DNA to replicate
Why use isotonic solution in DNA?
Isotonic solutions are used in DNA experiments to maintain the osmotic balance of cells and prevent them from bursting or shrinking due to osmotic pressure changes. This stability is crucial during processes like DNA extraction, where the integrity of the cell membrane must be preserved to effectively isolate DNA without damaging it. Additionally, isotonic conditions help ensure that cellular components remain intact for accurate analysis and manipulation of DNA.
Which step of mitosis involves the condensing of DNA into chromosomes?
The prophase phase is when DNA winds up into chromosomes. It winds up to remain organized. Cytokinesis is when the DNA unwinds again.
Why can only certain parts of DNA be used as DNA fingerprinting?
The parts must be unique to the person.The parts must be unique to the person
