How can you convert sticky ends into blunt ends?
To convert sticky ends into blunt ends, you can use the enzyme DNA polymerase to fill in the overhanging nucleotides. By adding the appropriate nucleotides complementary to the sticky ends, you effectively create blunt ends. Alternatively, you can use exonucleases to trim back the sticky ends, removing the overhangs and resulting in blunt ends. Both methods allow for the subsequent ligation of DNA fragments.
Would it be easier for DNA ligase to reconnect two fragments cut by EcoR1 or one fragment cut by EcoR1 with one cut by Hind111?
It would be easier for DNA ligase to reconnect two fragments cut by EcoR1, as both fragments would have compatible overhangs that can anneal together. In the case of one fragment cut by EcoR1 and one cut by HindIII, the overhangs produced by the two enzymes are incompatible, making it more challenging for DNA ligase to join them together.
Which protein creates DNA fragments with sticky ends?
Restriction enzymes are proteins that can create DNA fragments with sticky ends by cleaving DNA at specific recognition sequences. The sticky ends refer to single-stranded overhangs that are complementary to each other, allowing for the fragments to easily anneal to each other during DNA recombination.
What kind of molecule is EcoR1?
EcoR1 is a restriction enzyme (endonuclease), which splits the phosphodiester bonds of the backbone of DNA.
What happens when a restriction enzyme leaves blunt ends?
The restriction enzymes have ability to cut on a specific sequences that are knwon as palandreomic sequences now they cut in two way i.e. blunt and sticky for e.g. if we have a sequece of ATTCGTAAGC it will be cutted in two way as ...................................................TAAGCATTCG 1. ATTCG......... TAAGC i.e., blunt or straight form all ends ....TAAGC .........ATTCG 2. ATT .................CGTAAGC ....TAAGCAT .................TCG i.e., sticky or uneven ends The reason for this phenomena is still not clear or knwon

Which enzymes does not make sticky ends?
Enzymes that do not create sticky ends include blunt-end cutting enzymes such as SmaI and PvuII. These enzymes produce blunt-ended DNA molecules with no overhangs, making them unsuitable for creating cohesive ends for ligation.
Which protein creates DNA fragments with sticky ends?
Restriction enzymes are proteins that can create DNA fragments with sticky ends by cleaving DNA at specific recognition sequences. The sticky ends refer to single-stranded overhangs that are complementary to each other, allowing for the fragments to easily anneal to each other during DNA recombination.
What is a sticky end?
A Sticky End, referring to Biology is recombinant DNA. After DNA has been cut by a restriction enzyme it has "sticky ends" or recombinant DNA at the ends.
What kind of molecule is EcoR1?
EcoR1 is a restriction enzyme (endonuclease), which splits the phosphodiester bonds of the backbone of DNA.
Why are sticky ends called sticky?
Sticky ends are called "sticky" because the single-stranded overhangs created by certain restriction enzymes can bind to another DNA molecule with a complementary overhang, leading to the joining of the two DNA molecules. The complementary pairing between the sticky ends creates a temporary connection, similar to how something sticky adheres to another surface.
Do cdnas have sticky ends?
Generally, cDNA's do not have sticky ends - also known as overhangs. However, if the research requires it, they can be engineered to have overhangs
What are stick ends?
the enzymes cause sticky ends to form------------------------------------------------the question is WHAT ARE STICKY ENDS, not how are sticky ends formed.the answer is "single stranded pieces of DNA left at the ends of restriction fragmants"-simone :)The actual answer is: single-stranded ends of fragments of double-stranded DNA
How can putting sticky ends onto blunt ended molecules?
Adding sticky ends to blunt-ended molecules involves the use of specific enzymes, such as restriction endonucleases, which create overhanging sequences on DNA fragments. This allows for more efficient ligation during cloning processes, as the complementary sticky ends can base pair with each other, ensuring precise and stable connections between DNA fragments. Sticky ends enhance the specificity and yield of recombinant DNA molecules, making them a preferred choice in genetic engineering and molecular biology applications.

Why there are sticky and blunt end produced in DNA?
sticky ends are more specific and easier to ligate
