What is a xenologue?
A xenologue (also xenolog) is a gene sequence in which similar sequences can be found in different species, due to horizontal gene transfer.
Does a restriction enzyme generate the same size fragments in genomic DNA of different species?
No. A restriction enzyme cuts DNA when it finds a specific sequence. Different animals will have these sequences occur at different intervals so the length of the fragments won't be the same.
Why is the gene coding for ribosomal RNA or rRNA used for establishing phylogenetic relationships?
rRNA genes are actually conserved among species, they do not largely vary for each different strain or the subtypes of the same species! hence we are using rRNA sequences to identify the bacterium and place them on phylogenetic tree accordingly.
What diversity of species in a community refers to the?
Number of different species
Why the amino acid sequences in the cytochrome c protein of humans and chimpanzees aren't the same species?
because chimpanzes are epic. biology sucks
Two nucleotide sequences found in two different species are almost exactly the same This fact suggests that these two species probably?
May have similar evolutionary histories
When comparing cytochrome sequences among species what species is identical to humans?
Chimpanzee

When comparing cytochrome sequences among species, which of the following species is identical to humans?
Chimpanzee
DNA varies from species to species in its?
Relative amounts of nucleotide bases and sequences of base pairs
Closely related species show more in nucleotide sequences than distantly related species?
similarity
What is notion of homology?
Homology is a concept in biology that refers to similarities between different species due to shared ancestry. In genetics, homology refers to similar DNA sequences found in different species that are inherited from a common ancestor. Homologous structures in anatomy are organs or body parts that have a similar underlying structure but may have different functions in different species.
What is the best evidence that organisms of two different species share a common ancestor?
The best evidence that organisms of two different species share a common ancestor is the presence of homologous structures. These structures have similar features due to shared ancestry, even if they serve different functions in different species. Additionally, similarities in DNA sequences and developmental patterns can indicate a common evolutionary history.
How many spieces of crocodile?
Possibly 24 and growing...up until recently there were believed to be 23 species of crocodilians, but recent information suggests that West African Nile crocodiles are a different species. In addition, it is likely that the Dwarf crocodile will soon be divided into a couple different species.
How can a study of biochemistry help taxonomists?
Recent taxonoic evaluation is done by studying genetics. Genetics is the study of genes and genes have specific sequences now in every species there are some sequences which are similar and are known as consensus sequences that is they show some simillar pattern of sequences now by studying these one can relate to different or same speicies and then genera and so on.
What are the sequences of how cells form into species?
Cells--tissues--organs and organ systems---organisms.
Does a restriction enzyme generate the same size fragments in genomic DNA of different species?
No. A restriction enzyme cuts DNA when it finds a specific sequence. Different animals will have these sequences occur at different intervals so the length of the fragments won't be the same.
