Infektionszyklus und … T=2 icosahedral capsid protein ~ ViralZone Please click on a letter to go to that letter's table. 18.2). In this, gene expression, protein synthesis & genome synthesis occurs. The long tail fiber genes (genes 37 and 38) from the genome of T2 were replaced with those of the IP008 phage by homologous recombination. T2 phage is more properly called Enterobacteria phage T2.It is a virulent bacteriophage which infects Escherichia coli bacteria.It contains linear double-stranded DNA, and is covered by a protective protein coat. It encodes about 300 gene products. T2 was the first phage to be observed under the electron microscope (1942, Luria and Anderson), and it was utilized in the famous Hershey-Chase experiment (1952). T4, with a genome of 166 kbp, is the best-known of all the T phages. About 300 of its genes have been characterized. [Genome size is the total length of DNA in an organism. 3.2.A2 –Comparison of genome size in T2 phage, E.coli, D. melanogaster, H. sapiens and Parascaris equorum. 11. phage Virus (bacteriophage) T2 Phage. specific recombination of T2 phage Delbrück, S.E. The T2 phage is a typical one common group of phages. Bacterium. Nematode (roundworm) Caenorhabditis elegans … (A) The parts of the T4 sequence that are homologous to phage T2 gene 39 are shown as open boxes.The carboxyl-terminal 43 amino acids of T4 gene 39 and the amino-terminal 30 amino acids of gene 60 are contributed by the insertion (gray bars), and the presumed mobA homing … Protein sets from fully sequenced genomes. piece of chromosome breaks off and attaches to another chromos…. The smallest known genome is possessed by the … The largest known genome is possessed by the canopy plant Paris japonica – 150 billion base pairs.
