Certain repeated sequences in eukaryotes are flanked by short direct repeats, suggesting that they originated as transposable elements. These same sequences lack introns and possess a string of thymine nucleotides at one end. Have these elements transposed as DNA or through RNA sequences? Explain your reasoning.

A: Hemophilia -- It occurs in about 1 of every 5000 males .     Usually a inherited disorder in which…

Q: Know the name of the RNA molecule that is the initial product of the transcription of a eukaryotic…

A:

Q: do introns or 3′ untranslated regions of a gene have higher rates of nucleotide substitution?…

A: Introns are the regions that include non-coding regions of the RNA transcript. The introns are…

Q: Cystic fibrosis (CF) is an inherited disorder caused by different types of mutations, many of which…

A: CF is caused by a mutation in a gene called the cystic fibrosis transmembrane conductance regulator…

Q: man rhodopsin gene is 2675 nucleotides long from transcription start site to transcription stop…

A: The rho factor provides directions for creating a macromolecule referred to as rhodopsin. This…

Q: The overall structures of RNA polymerase and DNA polymerase are very different, yet their active…

A: DNA polymerase help in DNA replication whereas RNA polymerase help in transcriptions. Both have…

Q: The mRNA sequence 5' AUG AAA CAG GGA UAA 3' encodes a particular peptide of interest to your…

A: Gene is the segment of DNA (deoxyribonucleic acid) that is responsible for heredity and inheritance…

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
