Nucleic acid’s polymers are usually just referred to as RNA or DNA, depending on the variety of nucleic acids present.
Answer:
Crossing over between segments of homologous chromosomes.
Explanation:
Crossing over happens during prophase I of meiosis I
<h2><u>Answer:</u></h2>
The primary stage is prophase. The nucleolus vanishes and the two centrosomes start to frame the mitotic spindle. The axle extends between two inverse shafts f the cell. Next is the metaphase. The centromeres of the chromatid sets adjust at the focal point of the thematic axle.
At that point anaphase, the centromeres will part that isolates the chromatid combine. They are presently called chromosomes. The last stage is the telophase. The chromosomes will at that point frame a string like chromatin and for throb envelope, a nucleolus shows up.
