In: Biology
R-plasmids are plasmid vectors which encode what type of genes? (user thinks genes for replicases)
Homologous recombination results in a protein with which attributes? (user thinks it a protein with amino acid sequence)
Transduction is the process best described as? (the uptake of DNA by infection)
Ribosomal RNA sequencing is utilized to create phylogenetic relationships between organisnms due to the fact these genes are some conserved throughout evolution. T or F ( user thinks true)
5.) What domian contain Chromosomes consist of Exons and Introns (user thinks archea and bacteria)
Can someone just please help me better understand these questions?
ANSWER
enes present on R plasmids grant resistance to antibiotics or other bacterial growth inhibitors. example is bacterial R plasmid for penicillin that provides the resistance to the penicilin. R plasmids can also contain tra genes that allow plasmid to go from cell to cell.
DNA replication and repair of DNA damage are necessary to maintaining genetics of species and ensuring its transmission from progeny to offspring. this is he part of DNA homologous recombination Recombination plays role in this process by allowing genes to be sorted into different combinations. For example, genetic recombination results in the exchange of genes between paired homologous chromosomes during meiosis, increasing genetic diversity is one of its key role and DNA damage repair is also a role of homologous recombination.
Transduction is the transfer of DNA from one bacteria to another by means of bacteriophage. it is an efficient means for transferring the genetic information of one bacterial cell to another..
Ribosomal RNA sequencing is utilized to create phylogenetic relationships between organisnms due to the fact these genes are some conserved throughout evolution. this statement is true (T) accourding to endosymbiotic theory.
ANSWER
An exon is a coding region of a gene that have information needed to encode a protein. In eukaryotes, genes are made up of coding exons interspersed with non-coding introns. the (mRNA) is formed and nocoding region of the gene is removed that can be translated into a protein. this is also present in eukaryotes.
