How can one identify the 3' and 5' ends of DNA?
The 3' end of DNA has a free hydroxyl group on the third carbon of the sugar molecule, while the 5' end has a phosphate group attached to the fifth carbon. These structural differences can be used to identify the 3' and 5' ends of DNA molecules.
How many pieces of DNA would result from this cut?
Two pieces of DNA would result, one with 5' ends and another with 3' ends.
Does the 3' or 5' end of a DNA helix grow?
The 3' end of a DNA helix grows during DNA replication. The enzyme DNA polymerase adds nucleotides to the 3' end of the growing DNA strand.
Can you explain what is meant by the 5' and 3' ends of the nucleotide in DNA structure?
The 5' and 3' ends of a nucleotide in DNA refer to the specific positions on the sugar molecule within the nucleotide. The 5' end has a phosphate group attached to the 5th carbon atom of the sugar, while the 3' end has a hydroxyl group attached to the 3rd carbon atom. These ends are important for the directionality of DNA strands during replication and transcription processes.
What is 5' and 3' in DNA?
In DNA, 5' and 3' refer to the orientation of the carbon atoms in the sugar-phosphate backbone of the DNA strand. The 5' end has a phosphate group attached to the 5' carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3' carbon. DNA synthesis occurs in the 5' to 3' direction.

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

What sticky ends does EcoR1 create?
EcoR1 creates sticky ends with a sequence of 5'-GAATTC-3'. This results in protruding ends with a 5' overhang on both strands of the DNA.
What is 5' and 3' in DNA?
In DNA, 5' and 3' refer to the orientation of the carbon atoms in the sugar-phosphate backbone of the DNA strand. The 5' end has a phosphate group attached to the 5' carbon of the sugar molecule, while the 3' end has a hydroxyl group attached to the 3' carbon. DNA synthesis occurs in the 5' to 3' direction.
What enzyme pastes the sticky ends of a DNA?
It is called DNA ligase. Catalyzes the formation of a phosphodiester bond between a 3'-hydroxyl group and a 5'-phosphate group in DNA. This enzyme catalyzes the joining together of two single-stranded DNA segments which may be either parts of the same duplex or parts of different duplexes. This enzyme functions in DNA replication and in DNA repair by linking DNa fragments together.In biotechnology, is widely used the DNA ligase from bacteriophage T4 that catalyzes the formation of a phosphodiester bond between adjacent 3'-OH and 5'-P termini in DNA.
Why the strands in DNA are named as 3' and 5?
The strands of DNA are named 3' and 5' based on the carbon atom numbering of the sugar molecules in the DNA backbone. The numbering starts at one end of the sugar molecule (the 3' end) and proceeds to the other end (the 5' end). This naming convention helps to indicate the directionality of the DNA strands during processes such as replication and transcription.
List three ways that DNA technology could be used to improve the lives of humans?
1. Identify humans 2. Identify human remains 3. Trace human origins
What 3 letter number ends in e?
one
Why exonucleases are not used in r DNA technology?
Endonucleases are used in biotechnology because they are able to be applied to a specific part of a DNA sequence and will cut the DNA only in these locations. Exonucleases on the other hand have the following issues: 1) An exonuclease will digest and entirely consume DNA/RNA. As opposed to cut a specific location of DNA, they will eat the entire strand if they are not stopped. 2) They will only begin digestion at the ends of the DNA/RNA molecule. Circular plasmid DNA will not be affected by an exonuclease, because there are no beginnings or ends to the DNA sequence. 3) More over, as mentioned in (2) they will only begin digestion at the ends of the DNA sequences, thus they are much less accurate in where they begin cutting the DNA/RNA. Because of this lack of control of exonucleases, they are difficult to use and generally not used in biotechnological techniques.
