What enzyme joins pieces of DNA together?
Ligase is used to join DNA strands together
What is the difference between the Helicase and DNA polymerase enzme?
The helicase in a way unzipps the wound DNA. DNA Polymerase then matches the nucleotide bases with free floating one so that A matches with T (or in RNA U) and G matches with C. Creating two new strands of DNA and completing DNA replication.
How are restriction enzymes used to look for differences between DNA samples?
Restriction enzymes cleave, or open, the DNA so that a sample can be taken and gel electrophoresis can separate the strands of DNA. From there, DNA probes bind to certain strands in each sample and DNA fingerprints can show the differences.
If the DNA strands are matched up what does that mean?
This means the two strands of DNA are complementary.
What are the two strands DNA held by?
The two strands of DNA are connected by hydrogen bonds.
What must happen to DNA strands before transcription can begin?
DNA strands must unwind and the two strands must separate prior to transcription beginning. Once transcription is complete, the two strands join back together.
What occures when 2 strands unzip and the nitrogen bases pair with different nitrogen bases?
This is the process of DNA replication. A DNA strand in the nucleus of a cell, starts off by being "unzipped" by helicase (an enzyme). Then another enzyme, DNA polymerase matches the nitrogen bases (which are freely floating in the nucleus), of each half with their matches, this forms two identical strands, of DNA.

How many DNA strands do goldfish have?
10000 DNA strands.
What type of biology do DNA ligase belong to?
DNA ligase is a very specific enzyme used in microbiology. The enzyme is used to help join DNA strands together and is used for DNA replication and repair.

Restriction enzymes cleave, or open, the DNA so that a sample can be taken and gel electrophoresis can separate the strands of DNA. From there, DNA probes bind to certain strands in each sample and DNA fingerprints can show the differences.
How many strands is DNA made of?
DNA is composed of two strands of DNA nucleotides.
How many strands are there at the beginning of DNA replication?
At the beginning of DNA replication there are two strands of DNA nucleotides.
How many strands of nucleotides make up DNA double helix?
In dna there are 4 strands which join each part of the dna together, these are t and a , and g and c each one of these contains 200-3000 atoms depending on wether it dna or mrna
