    Have Been/Has Been

    Analysis of the genomes of humans, chimpanzees and macaques indicates that a DNA sequence thought to play a role in the production of these spines have been deleted in humans, but has been preserved in other primates.

    Could you explain me the part ...have been deleted in humans? a DNA sequence is singular, after the comma "has been" used its ok but why "has been" not used at first? I don't see any plural object.

    I'd imagine that it's an error.

    Re: Have Been/Has Been

    So, should have been "has been" right?

    Yes, I would say so.
