Homework Answers
When DNA melt and form an open helix that is 2 single-stranded DNA then single strand binding proteins bind to the single strands and stabilizes it. so the answer is Proteins.

44. During DNA replication, the double helix is unwound, creating two single strands. One of these is called the strand, on which the progress of DNA Polymerase III is – 45. The other strand is called the strand, on which the synthesis is 16. During DNA replication, synthesis of a new sequence on the Leading Strand is continuous. Why is synthesis on the Lagging Strand discontinuous? 47. Generation of Okazaki fragments proceeds in three steps. Indicate which of the following...

If this is right can you explain why others are wrong?
Question 1 Which of the statements about DNA replication is true? Single-strand binding proteins stabilize the open conformation of the unwound DNA. O Okazaki fragments are DNA fragments synthesized on the leading strand. ODNA polymerase adds dNTP monomers in the 3-5' direction. ODNA gyrase unwinds the DNA double helix.
