Designer Chromosome One of the ultimate aims synthetic biology is to build designer organisms from ground up. Rapid advances in DNA synthesis has allowed assembly complete bacterial genomes. Eukaryotic organisms, with their generally much larger and more complex genomes, present an additional challenge biologists. Annaluru et al. (p. 55 , published online 27 March) designed a eukaryotic chromosome based on yeast III. The chromosome, shorn destabilizing transfer RNA genes transposons, ∼14%...
Whether synthetic genomes can power life has attracted broad interest in the biology field. Here, we report de novo synthesis of largest eukaryotic chromosome thus far, synIV, a 1,454,621-bp yeast resulting from extensive genome streamlining and modification. We developed megachunk assembly combined with hierarchical integration strategy, which significantly increased accuracy flexibility construction. Besides drastic sequence changes, further manipulated 3D structure synIV to explore...
The retroviral Gag polyprotein directs budding from the plasma membrane of infected cells. Until now, it was believed that proteins type C retroviruses, including prototypic oncoretrovirus Rous sarcoma virus, were synthesized on cytosolic ribosomes and targeted directly to membrane. Here we reveal a previously unknown step in subcellular trafficking protein, transient nuclear localization. We have identified targeting signal within N-terminal matrix domain facilitates active import...
We designed and synthesized synI, which is ∼21.6% shorter than native chrI, the smallest chromosome in Saccharomyces cerevisiae. SynI was for attachment to another synthetic due concerns surrounding potential instability karyotype imbalance now attached synIII, yielding first yeast fusion chromosome. Additional chromosomes were constructed study nuclear function. ChrIII-I chrIX-III-I have twisted structures, depend on silencing protein Sir3. As a smaller chromosome, chrI also faces special...
A major challenge in undergraduate life science curricula is the continual evaluation and development of courses that reflect constantly shifting face contemporary biological research. Synthetic biology offers an excellent framework within which students may participate cutting-edge interdisciplinary research therefore attractive addition to curriculum. This new discipline promise a deeper understanding gene function, order, chromosome structure through de novo synthesis genetic information,...
The retroviral Gag polyprotein orchestrates the assembly and release of virus particles from infected cells. We previously reported that nuclear transport Rous sarcoma (RSV) protein is intrinsic to pathway. To identify cis- trans-acting factors governing nucleocytoplasmic trafficking, we developed novel vectors express regions in Saccharomyces cerevisiae. localization proteins was examined wild type mutant strains deficient members importin-beta family. confirmed Crm1p dependence identified...
ABSTRACT The Rous sarcoma virus (RSV) Gag polyprotein undergoes transient nuclear trafficking as an intrinsic part of the assembly pathway. Nuclear export is crucial for efficient production viral particles and accomplished through action a leptomycin B (LMB)-dependent signal (NES) in p10 domain (L. Z. Scheifele, R. A. Garbitt, J. D. Rhoads, L. Parent, Proc. Natl. Acad. Sci. USA 99: 3944-3949, 2002). We have now mapped activity to C-terminal portion sequence identified four hydrophobic amino...
Mobile elements are important components of our genomes, with diverse and significant effects on phenotype. Not only can transposons inactivate genes by direct disruption shuffle the genome through recombination, they also alter gene expression subtly or powerfully. Currently active highly polymorphic in host populations, including, among hundreds others, L1 Alu humans Ty1 yeast. For this reason, we wished to develop a simple genome-wide method for identifying all any given sample. We have...
Abstract Animal remains represent ephemeral resources that provide nutrients to a wide range of organisms. On death, vertebrate carrion is immediately colonized with variety microorganisms (typically obligate or facultatively anaerobic bacteria from the air, insects, corpse itself), which produce odors through breakdown tissues, alteration volatile chemicals present in environment, both. Within minutes, certain necrophagous flies are attracted by these chemical signals, resulting waves...
ABSTRACT Nucleocytoplasmic shuttling of the Rous sarcoma virus (RSV) Gag polyprotein is an integral step in particle assembly. A nuclear export signal (NES) was previously identified within p10 domain RSV Gag. mutants containing deletions NES or mutations critical hydrophobic residues at positions 219, 222, 225, 229 become trapped nucleus and exhibit defects efficiency release. To investigate other potential roles for trafficking replication, we created viruses bearing mutant proteins....
Yeast and mammalian genomes are replete with nearly identical copies of long dispersed repeats in the form retrotransposons. Mechanisms clearly exist to maintain genome structure face potential rearrangement between repeats, but nature this machinery is poorly understood. Here we describe a series distinct “retrotransposon overdose” (RO) lineages which number Ty1 elements Saccharomyces cerevisiae has been increased by as much 10 fold. Although these RO strains remarkably normal growth rate,...
The highly specialized nature of scientific research has erected substantial barriers between professional scientists and the laity, who have become distanced from process discovery. Do-It-Yourself Biology movement seeks to remove these impediments, with community laboratories serving as vehicles for public engagement participation in inquiry. We describe our experience establishing maintaining BUGSS lab Baltimore. While each is distinct its structure, culture, programming, we hope that this...

The COVID-19 pandemic has challenged undergraduate instructors and students in an unprecedented manner.
Synthetic biology projects aim to produce physical DNA that matches a designed target sequence. Chemically synthesized oligomers are generally used as the starting point for building larger and sequences. Due error rate of chemical synthesis, these can have many differences from As joined together make synthetic intermediates, it becomes essential perform quality control eliminate intermediates with errors retain only those molecules free respect target. This step is often performed by...
ABSTRACT Budding of C-type retroviruses begins when the viral Gag polyprotein is directed to plasma membrane by an N-terminal membrane-binding (M) domain. While dispersed basic amino acids within M domain are critical for stable association and consequent particle assembly, additional residues or motifs may be required specific targeting binding. We have identified assembly-defective Rous sarcoma virus (RSV) mutant that retains significant affinity despite having a deletion fourth...
