What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What is the difference between the target cell DNA and source DNA?
DNA is deoxyribo nucleic acid chains. If the DNA is taken from a source such as a micro organism or a plant is known as source DNA. Targe cells are where your construct is going to be transfected, target cells posses their own target cell DNA.
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.
What molecule is the source of information for transcription?
The molecule which carries the source of information is DNA. The process of stretching a DNA molecule into an RNA is the process known in genetic terms as the act of transcription.
What component of the DNA is the source of this information?
The genetic information in DNA is encoded in the sequence of nitrogenous bases (adenine, thymine, cytosine, and guanine) within the DNA molecule. These bases form specific sequences that determine the genetic instructions for an organism.
What are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
Describes flow of genetic information?
genetic information starts in the DNA, and moves to the polypeptide chain Source: Dr. Bruce Biegler PhD
Is DNA genetic code or genetic blueprint?
DNA is the genetic code
How long does DNA in hair last before it degrades?
DNA in hair can last for centuries before it degrades, as hair is a durable source of genetic material.
What did Oswald Avery's experiment prove?
Oswald Avery proved that DNA and not proteins were the source of genetic material.
Is a source of genetic variation that refers to a random error in the genetic code?
A genetic mutation is a source of genetic variation that refers to a random error in the genetic code. Mutations can occur spontaneously during DNA replication, as a result of environmental factors, or due to mistakes in cellular processes. These mutations can lead to changes in the DNA sequence, potentially resulting in genetic variation within a population.
