How many bivalents are present during metaphase 1 of meoisis in Drosophila where 2n10?
In Drosophila, which has a diploid chromosome number of 2n = 10, there are five pairs of homologous chromosomes. During metaphase I of meiosis, these homologous pairs align at the metaphase plate as bivalents. Therefore, there are five bivalents present during metaphase I in Drosophila with a diploid number of 10.
Is a centrioles found in all eukaryotics?
Centrioles are not found in all eukaryotes; they are primarily present in animal cells and some fungi and algae. Many higher plants and some protists lack centrioles entirely. Instead, these organisms utilize other structures for organizing microtubules during cell division. Thus, while centrioles play a key role in many eukaryotic cells, they are not a universal feature across all eukaryotic life.
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
How many chromosomes attach to each spindle fiber during metaphase 1?
Two chromosomes attach to each spindle fiber during metaphase I of meiosis.
How many chromosomes would a cell have during metaphase I of meiosis if it has 12 chromosomes during interphase?

In human cell undergoing mitosis how many chromosomes are present in prophase in metaphase in telophase?
In prophase, there are 46 chromosomes present, which are duplicated sister chromatids. In metaphase, there are still 46 chromosomes, but they are aligned along the metaphase plate. In telophase, the chromosomes have separated and there are once again 46 individual chromosomes in each daughter cell.
If the chromosomes number for a chimp is 48 how many dyads will it have in a somatic cell in metaphase?
A chimpanzee with 48 chromosomes will have 24 dyads in a somatic cell during metaphase. In metaphase, each chromosome consists of two sister chromatids, which are referred to as dyads.
Does prokaryotic cell have centrioles?
No, prokaryotic cells do not have centrioles. Centrioles are found in eukaryotic cells and are involved in organizing the microtubules during cell division. Prokaryotic cells lack many of the organelles found in eukaryotic cells.
How many are there in centrioles?
5?
How many chromosomes will it have during metaphase and how many sister chromatids?
During metaphase, a human cell will have 46 chromosomes, as humans have a diploid number of chromosomes. Each chromosome is replicated, resulting in a total of 92 sister chromatids, with each chromosome consisting of two identical sister chromatids joined at the centromere.
How many chromosomes are at the metaphase II equator?
There are two chromosome that are at the metaphase II equator. Chromosomes are already duplicated and are homologous pairs in Metaphase II.
Why is colchicine used for preparing a metaphase spread?
Colchicine is a drug that prevents tubulin polymerisation into cytoskeleton structures called microtubules. Microtubules are essential for many functions of the cell, but importantly are needed for cell division. Specifically, they help align homologous chromosomes on the metaphase plate during metaphase and then separate the chromosome pairs during anaphase. So by inhibiting the production of microtubules, the chromosomes never align on the metaphase plate - they will be fully condensed but spread throughout the cell, a situation called a metaphase spread
