Question

steps of dna replication

1. dna separation

• unwinds the dna helix.
• separates the two strands.
• proteins keep strands apart.

1. temporary fix

• adds rna nucleotide to exposed dna

1. adding new

• adds complementary dna bases.
• works only in the → direction.
• strand = builds dna continuously from 5-3
• strand = built dna from 5-3 in fragments called fragments.

1. putting it together

• dna joins okazaki fragments together into one continuous strand.

Explanation:

DNA replication involves several key steps. Helicase unwinds the DNA helix, single - strand binding proteins keep the strands apart, and DNA polymerase adds complementary DNA bases. Primase adds RNA nucleotides to start the process. DNA polymerase works in the 5' - 3' direction. The leading strand is built continuously and the lagging strand in Okazaki fragments which are joined by DNA ligase.

Answer:

1. Helicase; Single - strand binding;
2. Primase;
3. DNA polymerase; 5'; 3'; Leading; Lagging; Okazaki;
4. Ligase
