During Prophase chromosomes condense, and mitotic spindle form, chromosomes are copied, and the nuclear membrane disappears, spindle fibres pull the sister chromatids apart.
Explanation:
Prophase is divided into 2 sub-phases as early Prophase and late prophase.
Early Prophase:
In early prophase distinct thick chromosome like structures, Centrioles move to the opposite poles and, nuclear membrane disappears
By late prophase:
Astral rays and spindle fibres are formed. Spindle fibres attach to the chromosome. Contractions occur in the attachment and sister chromatids are pull apart towards the equator.
Metaphase will follow the prophase.
Answer:
DNA stores biological information in sequences of four bases of nucleic acid
Explanation:
DNA stores biological information in sequences of four bases of nucleic acid — adenie (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix. ... Taken as a whole, this package of DNA serves as its owner's complete genetic blueprint.
Light intensity, wind, temperature, humidity
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
