3.3 The Nucleus and DNA Replication – Anatomy
WebWe have inserted a yeast nuclear DNA fragment bearing the TRP1 gene and its associated origin of DNA replication, ARS1, into the functional mitochondrial chromosome of a strain carrying a chromosomal trp1 deletion. TRP1 was not phenotypically expressed within the organelle. However, this Trp- strain … WebAlthough most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA. In humans, mitochondrial DNA spans about 16,500 DNA building blocks (base pairs), representing a small fraction of the total DNA in cells. mcdonald\\u0027s 96th street surrey
