Question

short segments of newly synthesized dna are joined into a continuous strand by
primase
dna polymerase
ligase
helicase
single - strand binding protein

Explanation:

• Primase: Synthesizes RNA primers, not joining DNA segments.
• DNA polymerase: Synthesizes DNA strands by adding nucleotides, not joining short segments.
• Ligase: Catalyzes the formation of phosphodiester bonds between adjacent DNA fragments (Okazaki fragments), joining them into a continuous strand.
• Helicase: Unwinds the DNA double - helix, not involved in joining segments.
• Single - strand binding protein: Stabilizes single - stranded DNA, not for joining segments.

Answer:

ligase
