8. DNA transposons a. infrequently rearrange chromosomal DNA b. experience a grand frequency of recombinations as well as disunions of nucleotides at chromosomal termini. c. infrequently participate in inversions of a sector of DNA d. tend to participate in distant (as opposed to local) transpositions e. possess transposase, which tends to transpose into open reading frames of genes 9. DNA transposons a. contain transposase, which is able to induce the union of termini of distinct copies of a transposon, which may be followed by partial or complete cut-and-paste actions b. contain transposase, which may induce inversions or duplications, but not deletions c. include representatives that are currently active in humans d. contain transposase (gene), whose derivatives (rag1 and rag2) participate during embryogeny in the positive selection of antibodies and T-cell receptors that are able to recognize "self" tissue e. originate V(D)] recombinations in genic sectors of interleukins and interferons 10. V(D)J recombination. a. is a term whose letters denote "virtual," "dual" and "joining" b. is an adult process in which B-cell receptors and T cells experience genic selection c. produce as many as 500,000 (maximum) permutations of genes d. occurs in reproductive cells e. occurs in T-lymphocytes and B-lymphocytes, producing millions of genes that experience selection that prevents the T-cells and B-cells from recognizing a body's own tissues 11. SETMAR a. encodes a single-domain protein b. possesses one domain that is a transposase and another domain that methylates lysines of a particular histone asqo no c. confers vulnerability of its host to ionizing radiation d. exists in prosimians e. minimizes nonhomologous end-joining (alligation of termini of genic sectors) 12. Retroviruses. a. are unable to enter the genome of their hosts oganso soubory b. reverse transcribe a single-stranded copy of their genome into the DNA of their host c. that exists in hosts' chromosomal DNA (as opposed to existing external to hosts) are universally denominated endogenous retroviruses (ERVs) d. include ERV-9, whose copies number = 700-1500 in the human genomen e. include ERV-9, which engender activity of enhancer/promoter complexes 13. ERVS. a. exhibit transcriptional control on a novel transcript of p63 b. regulate p63, which is a recent member of the p53 (PT53) family of tumor suppressor genes c. include ERV-9, which regulates isoforms of p63 that participates in replenishing human stem cells of muscle d. are less prevalent in the human genome than protein-coding genes are e. maintain the stability of the male germ line in cancerous testicular cells 14. ERV-9s(). a. which control RNA transcripts spatially and temporally, maintain stability of both female and male salutary germ lines b. may be suppressed by recombinations or mutations, but not by epigenetic actions c. exist either on one side or the other of long terminal repeats d. control the transcription of "germ cell-associated transcriptionally active" p63 (GTAp63), which is expressed in spermatozoa (mature sperm) e. control the transcription of GTAp63 that is expressed in cancerous testes 8.
