Question

Which of the following statements describes the lysogenic cycle of lambda (lambda) phage? After infection, the viral genes immediately turn the host cell into a lambda-producing factory, and the host cell then lyses. Most of the virus genes are immediately activated by the product of a particular virus gene. The phase genome replicates along with the host genome. Match the lettered choices with the numbered questions. Letters may be used more than once. E site P site A Site New t-RNAs come to the _ of the ribosome. miRNA siRNA pi RNA Both miRNA & siRNA Induce formation of heterochromatin & block expression of transposons Degrade mRNA or block translation Histone Phosphorylation Histone acetylation DNA methylation Condenses chromatin to inactivate (Exs: inactivated X chromosome and genomic imprinting) nucleoid capsid viral envelope specifically surrounds viral genome prions DNA or RNA protein coats. metabolism evolutionary' adaptations Viruses lack _, and thus are generally not regarded as alive. reads mRNA attracts i-RNAs with amino acids catalyzes peptide bonds All of these Ribosome function Alu sequences Long segment DNA L1 sequences transposable elements All of these Repetitive DNA exons introns 5' cap promoter terminator TATA box Removed by spliceosome
