검증된 단계별 안내1
Begin by understanding the structure of DNA. DNA is composed of long chains of nucleotides, which are the basic building blocks.
Recognize that chromosomes are large structures within cells that contain many genes and are made up of long strands of DNA.
Understand that genes are specific sequences of nucleotides within the DNA that code for proteins or functional RNA.
Learn about Okazaki fragments, which are short segments of DNA synthesized on the lagging strand during DNA replication. They are later joined together by the enzyme DNA ligase.
Identify that nucleotides are the individual units that make up DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
