There is not really such a thing as a mirror image of DNA in nature. DNA polymerase may be the "molecule" that you are thinking of, it is an enzyme that replicates DNA. When the polymerase makes a new strand of DNA, it uses an existing strand of DNA as a template. The new strand of DNA is not in fact a mirror image of the template strand, but it is the closest thing possible. The new strand is called a complementary strand, not a mirror image.
Existing DNA (template for polymerase): ATC TGA CCG GAC TAG GGT
New strand (made by polymerase): TAG ACT GGC CTG ATC CCA
Alternatively, by mirror image of DNA you may be thinking of RNA, a ribonucleotide that is made by RNA polymerase. The process is similar to that described above, but the new complementary strand is made out of ribonucleic acid rather than deoxyribonucleic acid.
What else can I help you with?
Is plasmid located in the nucleus or cytoplasm?
No they are not in the nucleus. They are in the cytoplasm.
When does DNA replicate during the cell cycle?
DNA replicates during the S phase of the cell cycle.
Molecules of extrachromosomal DNA are also known as?
Extrachromosomal DNA molecules are also known as plasmids. These are small circular DNA molecules that replicate independently of the chromosomal DNA in bacteria and other organisms. Plasmids often carry genes that provide additional functions to the host cell, such as antibiotic resistance.
At what specific stage of the cell cycle does DNA replicate?
DNA replicates during the S phase of the cell cycle.
Small DNA loops are called?
Small DNA loops are called plasmids. Plasmids are small, circular DNA molecules that are separate from the chromosomal DNA of a cell. They are often found in bacteria and can replicate independently.
How does the cell replicate DNA?
Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.
What is the principal function of dna?
The function of DNA is in HeridityThe genetic information store in the nucleotide sequence of DNA serves two purposes-1. It is the source of i for the synthesis of all protein molecules of the cell & organism2. it provides the information inherited by daughter cells or offspring.To store a cell's genetic information, and to replicate and pass on genetic information to offspring.
Why must cells be able to both transcribe and replicate their DNA?
The DNA only needs to replicate if the cell is going to divide. In a dividing cell the DNA must replicate in order to provide a complete copy of the genome to each new cell.
Where does DNA replicate occur in the cell?
In the cell nucleus
What does DNA do to a cell?
DNA is the genetic "instructions" for how the cell should replicate. It also controls the behavior of the cell.
Is plasmid located in the nucleus or cytoplasm?
No they are not in the nucleus. They are in the cytoplasm.
When does DNA replicate during the cell cycle?
DNA replicates during the S phase of the cell cycle.
Where does a virus replicate its DNA?
A virus replicates its DNA in a cell when it infects the host
Why is it necessary the cell copies its DNA?
cells must copy their DNA to replicate
Molecules of extrachromosomal DNA are also known as?
Extrachromosomal DNA molecules are also known as plasmids. These are small circular DNA molecules that replicate independently of the chromosomal DNA in bacteria and other organisms. Plasmids often carry genes that provide additional functions to the host cell, such as antibiotic resistance.
How many molecules would there be after four DNA molecules unzip and replicate?
When four DNA molecules unzip and replicate, each original molecule produces two new strands, resulting in a total of eight molecules. Specifically, each of the four original DNA molecules yields two identical daughter molecules, leading to 4 original + 4 new = 8 DNA molecules in total.
Where does DNA replicate take place in the cell?
DNA replication takes place in the chromosome which is located in the nucleus of a cell.
