A single-stranded non-circular DNA molecule has two non-identical ends, the 3' end and the 5' end (usually pronounced "three prime end" and "five prime end"). The numbers refer to the numbering of carbon atoms in the deoxyribose, which is a sugar forming an important part of the backbone of the DNA molecule. In the backbone of DNA the 5' carbon of one deoxyribose is linked to the 3' carbon of another by a phosphate group. The 5' carbon of this deoxyribose is again linked to the 3' carbon of the next, and so forth.

∙ 10y ago5' and 3' are referring to the different ends of a DNA strand. The 3' ("three prime") end has a hydroxyl group (OH) and the 5' ("five prime") end has a phosphate group. Every DNA strand has both a 3' and a 5' end.
This means that the two ends of DNA can act differently in relation to things like enzymes (such as DNA Polymerase).

Does the 3' or 5' end of a DNA helix grow?
DNA is linear, so there must be two ends to it. (Prokaryote circular genomes have a 5' and 3' end as well, but only for directional purposes).
Why the strands in DNA are named as 3' and 5?
3' and 5' refer to the ends of a strand. The 3' end will have the 3rd carbon on the deoxyribose sugar unbound. The 5' end will have the 5th carbon on the deoxyribose sugar unbound. As chains are antiparralel in the DNa duplex 5' of one strand will be next to 3' of the other. Hope that helps
DNA how do you tell if a DNA strand begins with the 5 prime or the 3 prime?
The 5 prime end of DNA has phosphate group while the 3 prime end has a hydroxyl group.
In what direction can a DNA polymerase work when catalyzing the addition of nucleotide monomers to build a strand of DNA?
DNA is polymerized in the 5' to 3' direction.
In which direction does RNA polymerase read a DNA strand?
The correct answer is: RNA is synthesized by RNA polymerase that reads one strand of DNA. RNA polymerase reads DNA 3' to 5'. When RNA is made, it is made 5' to 3'. Most polymerases have the 3' to 5' "reading" activity. The created RNA strand is identical to the coding strand of DNA, which is also in the orientation of 5' to 3'.
Match this sequence of DNA 5-caagtggaat-3 with its complementary DNA strand?
3-gttcacctta-5
What is the anti parallel DNA strand of 5'-C-C-A-T-C-T-T-G-3'?
DNA ends 3 to 5, 5 to 3 polarity. opposite ends of DNA synthesis 3 OH, 5 PO DNA always have antiparallel configuration
When DNA replicates what are the new DNA made of?
its made of DNA. Replication just doubles the DNA, just like when bacteria or humans replicate.. the new human is .. well made of human.... It is opposite and anti-parallel.... 5-AATGTC-3 Original strand 3-TTACAG-5 new strand Each new molecule will have 1 original strand, and 1 daughter/newly synthesized strand. DNA replication results in DNA DNA transcription results in a strand of RNA
Complementary strand of dna AAT?
Answer and Explanation: For the sequence 5′-GATTACA-3′, the complementary DNA strand would be 3′-CTAATGT-5′. Often, DNA strands are written in the 5′ to 3′ direction, so the complementary strand would be 5′-TGTAATC-3′ when written 5′ to 3′. What is complementary to mRNA?

What is the complementary DNA chain of 5'-AATGSTA-3'?
Do you mean complementary DNA chain of 5'-AATGCTA-3' (not 5'-AATGSTA-3')A(adenine) bonds with T(thymine) and G(guanine) bonds with C (cytosine). So the complementary DNA strand would be: 3'-TTACGAT-5' .

The 5 prime end of DNA has phosphate group while the 3 prime end has a hydroxyl group.

How does DNA reproduction take place?
In the nucleus of the cell, DNA replicates by the work of DNA Polymerase III copying the 5' to 3' strand while DNA Polymerase II ligates the Okazaki fragments on the 3' to 5' lagging strand.
What is attgcat complementary strand sequence?
In DNA: 5' attgcat 3' 3' taacgta 5'
