Which of the following is an example of how taxon classification might change?
Scientists recognize a new sub-species of tiger based on newly discovered DNA patterns.
What is a following reactions that is used to radioactively label DNA?
Synthesis of new DNA.
At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
What enzyme builds new DNA strands from existing strands during DNA replication?
DNA Polymerase III is responsible for adding new nucleotides to the strand being synthesised. Also involved in DNA replication are DNA Polymerase I which replaces primers with nucleotides, and DNA Ligase which joins fragments of DNA together.
Which enzymes catalyzes the elongation of a new DNA strand?
DNA polymerase catalyzes the reactions that are responsible for synthesizing new DNA strands in the 5' to 3' direction. The parent DNA strand is read in the 3' to 5' direction but the daughter strand is extended in the opposite direction.
How do new traits arise to create genetic variability?
Random mutations of DNA happen and these get inserted into the gene pool as the species breed.
Which of the following is an example of how taxon classification might change?
Scientists recognize a new sub-species of tiger based on newly discovered DNA patterns.
How is sympatric similar to allopatric speciation?
They both are mechanisms by which new species arise grad point
If you agree with B F Skinner as to the nature of personality you would also agree?
humans are infinitely changeable because they can learn new behavior patterns.
Difficulties that might arise in creating a new business?
what are the difficulties that might arise in setting up a new business
When human DNA is spliced into bacterial DNA what is the new DNA called?
The new human-bacterial DNA is known as recombinant DNA.
How do new specie arise?
Because new species have to adapt to their newly acquired surroundings.
Most polyploid species arise from?
Aliens .... They come in UFO's and arise new polyploid species.
Why is recombinant DNA a new form of DNA?
Recombinant DNA is a new form of DNA because it is created via introduction of the relevant DNA into the existing organismal DNA.
Why is recombination DNA a new form of DNA?
Recombinant DNA is a new form of DNA because it is created via introduction of the relevant DNA into the existing organismal DNA.
What enzyne produces a new DNA strand during DNA replication?
The DNA polymerase enzyme produces a new DNA strand during DNA replication
When DNA splits a new 'what' of DNA is formed?
A new strand of DNA exactly alike to the original is created.
