How do genomes of species change?
By mutations in DNA.
The scientific field that studies whole genomes is called?
Genomics
How many genomes does a plant cell have?
The largest genome in a plant cell is DNA in its nucleus. However, two organelles in the cell, the mitochondria and chloroplasts each have their own DNA as well, so a plant cell can have up to three different genomes.
What is the most significant physical component of the theory of evolution?
The genomes of individual organisms and the populations gene pool.
The relationship between electrons and life?
The relationship between electrons and life is the tiny subparticles react with the nuetrons creating a friction that keep are basic genomes going.
What is the function of a vector in biotechnology?
In Biotechnology, vectors are used to transport and insert specific DNA sequences into target genomes.
Chromosome of a bacterium?
Bacterial genomes are termed as chromatid in contrast to complex chromosome structures of eukaryotes
What does geneticly engineered corn do to you?
Makes you less hungry.Keep in mind that humans have been manipulating the genomes of food crops for thousands of years by selective breeding. Modern methods simply speed the process.
Are viral genomes larger or smaller as eukaryote genomes?
smaller
Why Bacterial DNA is used frequently in genetic engineering?
Bacterial genomes are relatively small and some (eg. E. coli) are very well characterised. Also, most bacteria have a very short generation time so any DNA that is inserted can be multiplied quickly.
What is the main component of most bacterial genomes?
double-stranded circular DNA molecules that is associated with a small amount of protein
Are genomes made of proteins?
No; genomes are made from DNA or RNA, which are nucleic acids,
What are the occasional mistakes in copying DNA called and why are they significant for evolutionary change?
Mutations. They, when beneficial, provide variations of organisms genomes for natural selection. Beneficial mutations may confer a slight reproductive advantage to the organism so that genes " promoted " into the next generation change the allele frequency of the population causing evolution.
Where are genomes found?
Genomes are found in the nucleus of eukaryotic cells, which contain the DNA responsible for encoding all the genetic information of an organism. In prokaryotes, such as bacteria, genomes are found in the nucleoid region, which is not a true nucleus but contains the DNA. However, some organisms also have genomes in other cellular compartments, such as mitochondria or chloroplasts.
What is a unique feature of mtDNA?
out of the more than 1,000 mtDNA genomes within the cell, a new mutation in one of the mtDNA genomes can be replicated each time the cell divides, thus increasing the number of defective mtDNA genomes
When was the word genomes created?
around the 1700s
What is the study of genomes with or among species?
Genomics
