What does DNA pictures under a microscope?
That is when the DNA is condensed, at which time it is called chromosome.
How many time nuclus divided in meiosis?
The nucleus divides twice during meiosis. The first division is known as meiosis I, where homologous chromosomes separate, and the second division is known as meiosis II, where sister chromatids separate. This process results in the formation of four haploid daughter cells.
What phase of mitosis takes the least period of time?
Anaphase is typically the phase of mitosis that takes the least amount of time. During anaphase, the sister chromatids are pulled apart and move toward opposite poles of the cell, a process that occurs rapidly to ensure proper chromosome segregation. The quick separation is crucial for maintaining genetic stability in the daughter cells.
What happens during the cross-over in meiosis?
This is done by one of Mum's chromosomes swapping a segment of DNA with one of Dad's chromosomes. In the first prophase of meiosis (prophase I) each chromosome contains two molecules of DNA. You can see these as the two sister-chromatids of each chromosome. During this prophase, each chromosome pairs with the corresponding chromosome from the other set. In other words, the chromosome 1 from the male parent aligns itself beside chromosome 1 from the female parent, the two copies of chromosome 2 do likewise, and so on. The two copies of one chromosome are called homologous chromosomes.Each pair of chromosomes is called a bivalent, and consists of four chromatids twisted around each other. At various points along this bivalent, two non-sister chromatids will break at the same locus (point along the DNA) and recombine, so that now a stretch of DNA from Mum has attached to a stretch from Dad, and vice versa. On average, this crossing-over happens three or four times along the length of a chromosome, so that one DNA molecule now consists of alternating segments from each parent. Because no two parents are genetically identical, the recombined DNA has a base sequence that is different from that supplied by either parent. It is like a linear mosaic. The positions of crossing-over are pretty well random, so every time meiosis takes place in one individual novel base sequences are generated.
What event typically begins in anaphase and is completed by the end of telophase?
One event that typically begins in anaphase and is completed by the end of telophase is chromosome segregation. During anaphase, sister chromatids separate and move to opposite poles of the cell. This process continues into telophase, where two distinct daughter nuclei are formed.

Should I get a chihuahua at the same time as my sister?
You should not buy it at the same time as your sister. Because if you do your sister's chihuahua will fight with yours. And you need to wait for your sister to buy it first because when you look at your sister's chihuahua you can decide which chihuahua is prettier
In 1901 which car was seen for the first time?
Porsche
Is this sentence grammatically correct This is the first time you see it?
No, I think the correct way is- Is this the first time you've seen it?
How do you make a sentence with the word beleiving?
im believing in my sister for the first time
When a chromosome has been duplicated it consists of two identical pieces attached together called?
Oh honey, it's called a "sister chromatid." Think of them as the ultimate BFFs, always sticking together through thick and thin. So next time you see those duplicated chromosomes, just remember they're twinning like there's no tomorrow.
What was the date the Giant Panda was first seen?
The Giant Panda was first seen by ancient Asians. No written history exists from time that long ago.
When was Jesus first seen?
In his time, in the mid 1-30s A.D
Who saw an atom for the first time?
No one has ever seen an atom
What should you say to a girl that you have not seen in a long time the first time you call her?
lets get together
What was your favorite part of the deadly sister?
Did not watch it yet... Heard name for the first time...
When was settled agriculture first seen in china?
Settled agriculture was first seen in China around 7500 BC. The crops grown at this time were rice and millet.
