Select one:
a. The two strands form continuously, catalyzed by DNA polymerase.
b. The two strands form continuously, catalyzed by DNA ligase.
c. One strand forms continuously, the other forms in short segments
spliced by DNA polymerase.
d. One strand forms continuously, the other forms in short segments
spliced by DNA ligase. - ,,,answer,,,,..d. One strand forms continuously,
the other forms in short segments spliced by DNA ligase. There is a
leading strand and a lagging strand; they don't both form continuously.

a. Actin and myosin filaments remain stationary.
b. Actin and myosin myofilaments shorten.
c. Sarcomeres and myofibrils contract.
d. Sarcomeres and myofibrils lengthen. - ,,,answer,,,,..c. Sarcomeres and
myofibrils contract. The shortening of sarcomeres is responsible for
contraction, and thus myofibrils (sarcomeres joined end to end) also
shorten
