A factor that tends to cause species to change is a?
A factor that tends to cause species to change can be one of two things. It can be either climate change or an invasive species.
What is a change in the sequence of bases in DNA molecules called?
The change in the order of the bases in a DNA molecule is called a mutation. Such changes may happen because of damage to genomes, replication errors, or insertion or deletion of nucleotide bases.
How do you know that there is a process called evolution?
Evolution is the change in allele frequency over time in a population of organisms. Sequence the genomes of enough organisms in that population at two varying points and you will see the fact of evolution.
What type of evolution is a slow change of one species to another?
Isolation of population and impact of climate change creates speciation. It is the method of slow change of one species to another.
The scientific field that studies whole genomes is called?
Genomics
What is the study of genomes with or among species?
Genomics
An understanding of the human genome is aided by an understanding of?
the genomes of model species.
Natural selection leads to changes in both the physical appearance and what of a species?
And changes in allele frequency of populations; genes in genomes. Also in the behavioral repertoire of species.
Are viral genomes larger or smaller as eukaryote genomes?
smaller
What is bioinformatics?
Bioinformatics is basically using computers to organize and analyze biological data, like comparing genomes between organisms or species.
Are scientists done mapping out genes?
Scientists have mapped the whole human genome but are still mapping other species genomes such as mice and worms
Are genomes made of proteins?
No; genomes are made from DNA or RNA, which are nucleic acids,
What do you mean by genomic in situ hybridisation technique?
Genomic In Situ Hybridization refers to use of total genomic DNA from one species as a probe for in situ hybridization to identify chromosomes, chromosome segments, or whole genomes originating from that species in a hybrid or backcross.
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 does Mb mean in genomes?
million bases
