A strand of replicated DNA formed during prophase is a?
To put it simply, during Mitosis the chromosomes are first replicated (copied) and then distributed into 2 new "daughter" cells. They are replicated during the S phase of interphase, and in the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at which point the cell divides. idkidk the strand of chromosomes split like the cell during mitosis. They split in half.
When a DNA molecule replicated what is the relationship between the original strand and newly formed strands of DNA?
Not in general replication as the leading strand is replicated straight away. The lagging strand is replicated in pieces that need ligase to affix them, one to the other. However, in a replication bubble, when a lagging strand runs into a leading strand, and later the primers are replaced, ligase is still needed. Therefore, technically, the leading strand does need the ligase once.
Okazaki fragments are created during DNA replication because DNA Polymerase can only add nucleotides in a 5' to 3' direction. This means that one strand (the leading strand) can be continuously created, but the other strand (the lagging strand) runs in the opposite direction. This means that loops must be created and shorter parts of DNA replicated one at a time. This creates fragments on the lagging strand. The RNA primers on this strand are…
