The deoxyribonucleic acid (DNA) polymerase of Rous sarcoma virus synthesizes both single- and double-stranded DNA, utilizing the ribonucleic acid (RNA) of the viral genome as the initial template. Results of pulse-chase experiments indicate that the single-stranded DNA serves as unconserved template and precursor for the synthesis of double-stranded DNA. The latter reaction is apparently initiated in association with the viral RNA and may involve a partially double-stranded intermediate form.
劳氏肉瘤病毒的脱氧核糖核酸(DNA)聚合酶以病毒基因组的核糖核酸(RNA)为初始模板,合成单链和双链DNA。脉冲追踪实验结果表明,单链DNA作为双链DNA合成的非保守模板和前体。后一种反应显然是与病毒RNA相关联启动的,可能涉及一种部分双链的中间形式。
