In 1997, Dolly the sheep was cloned. Which of the following processes was used? transfer of an adult cell's nucleus into an enucleated sheep egg, followed by incubation in a surrogate separation of an early stage sheep blastula into separate cells, one of which was incubated in a surrogate ewe replication and dedifferentiation of adult stem cells from sheep bone marrow isolation of stem cells from a lamb embryo and production of a zygote equivalent Rank the following one-base point mutations with respect to their likelihood of affecting the structure of the corresponding polypeptide (from most likely to least likely). 1. insertion mutation deep within an intron 2. substitution mutation at the third position of a codon in an exon 3. substitution mutation at the second position of a codon in an exon 4. deletion mutation within the first exon of the gene 2, 1,4,3 3, 1,4, 2 4, 3, 2, 1 1, 2, 3, 4 Which of the following statements accurately describes the differences between DNA replication in prokaryotes and DNA replication in eukaryotes? Prokaryotic chromosomes have histones, whereas eukaryotic chromosomes do not. The rate of elongation during DNA replication is slower in prokaryotes than in eukaryotes. Prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many. Prokaryotes produce Okazaki fragments during DNA replication, but eukaryotes do not.
