b) metaphase)
c)anaphase
d) telophase
I need help!
Prophase: Replication of chromosomes and chromosome become visible x shapes.
Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.
Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.
Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.
Ladies and gents this has been Mitosis.
Answer:
Nucleic acids are important because they make up genetic information in living things. There are two types of nucleic acid and they are DNA and RNA. DNA is the basic instructions for living things. It is passed down from parent to offspring and is found in the nucleus of the cell.
Explanation:
Answer:
store genetic information
Explanation:
Answer:
He discovered the cell nucleus and realized that inside the nucleus there was an unknown chemical substance. That substance was DNA.
Explanation:
Who discovered the DNA was Friedrich Miescher, a Swiss biochemist with great talent. Miescher, using substance precipitation techniques, such as pH changes in the medium, was able to discover and isolate the cell nucleus. Inside the nucleus he was able to isolate a previously unknown substance. It was the nucleic acid, DNA, which, at the moment, with the technology available until then, presented itself only as a white, flocculent precipitate, which Miescher would later call nuclein.
In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.
To sum it up the answer is yes.
