Question
Vectors can transfer DNA sequences into bacterial host cells for cloning DNA sequences into viral bost cells for cloning cloned viral cells into a bacterial host for cloning cloned mitochondria from donor cell to host cell cloned chromosomes from the nucleus of a cell into its cytoplasm Most often, genomic library screening uses a labeled, complementary single-stranded RNA or DNA molecule called a probe colonies of vector bacteria on a Petri dish in order to replicate the desired genome recombinant plasmids containing DNA and DNA ligase cut plasmids containing recognition sites used to carry DNA molecules tRNA polymerase copies with a truncated copy of a DNA template Nuclear transfer is a preferred method of cloning over embryo splitting because it is less technical is more natural results in a large number of cloned offspring produces both male and female offspring from the same clone Uses haploid nuclei The analysis of only one STR is needed to obtain a DNA profile that is statistically unique to a given individual True False Golden rice contains a transgene that allows for increased production of vitamin A True False Before biotechnology became available, human proteins used in treatment of diseases were unavailable synthesized chemically free of contaminating factors harvested from slaughterhouses, donated human blood or cadavers harvested from transgenic plants Embryonic stem cells derived from blastocysts are pluripotent, and therefore useful in stem cell research because they are viable under a wide range of laboratory conditions do not replicate and are therefore stable long-term can form all cells, tissues, and organs of the human body are specialized and therefore arrested in G0 function to replace damaged or diseased body pans in adults Induced pluripotent stem cells (iPS cell, ) are produced by transferring a vitamin A gene into rice plant reprogramming adult cells by transferring certain master control genes into the cells' nuclei mutating certain genes in human blastocysts harvesting multipotent stem cells from umbilical cord bloodExplanation / Answer
Question 9.
Correct option is option a).
Vectors can transfer DNA sequence into bacterial host cells for cloning
Explaination:
Plasmids act as vector to transfer foreign DNA into bacterial cells. Plasmid is circular extrachromosomal DNA, that can independently replicate (becuase they carry bacteria specific origin of replication 'ori'). Foreign gene can be inserted into these plasmids at appropriate site using restriction enzymes and ligase enzymes. The recombinant plasmid thus, formed is transformed into the bacterial host.
