In the nucleus, DNA wraps around proteins called histones to form structures known as nucleosomes which further condense into chromosomes during cell division.
In the nucleus of eukaryotes, the DNA is wrapped around proteins called histones to form structures known as nucleosomes. These nucleosomes are likened to 'beads on a string' where the 'beads' are the histone proteins with DNA wrapped around them, and the 'string' is the DNA linking each nucleosome. These nucleosomes further condense into a 30 nm fiber and eventually form the tightly compacted structure of a chromosome, particularly during the metaphase stage of cell division.

Since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, option C is correct. as there would be four different types of gametes possible in this system.
In a system where skin color in a certain species of fish is inherited via a single gene with four different alleles, the number of different types of gametes that would be possible can be determined using the principle of independent assortment.
The principle of independent assortment states that during gamete formation, the alleles for different traits segregate independently of each other.
Since there is only one gene involved in determining skin color in this case, we can assume that the alleles for skin color segregate independently as well.
With four different alleles for the skin color gene, let's label them as A, B, C, and D. Each individual gamete will carry only one allele. The possible combinations of alleles in the gametes can be calculated by multiplying the number of alleles for each gene together.
In this case, since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, the correct answer is C) 4, as there would be four different types of gametes possible in this system.

Explanation:
Charles Darwin in the Galapagos. Perhaps our first association with the word "Galapagos" is the name "Darwin." Darwin's visit to the Galapagos Islands had a resounding impact on the formation of his Theory of Natural Selection. ... After surveying the coasts of South America, the ship stopped over in the Galapagos Islands.
Answer: visited and took samples to right about his book
Explanation: hope that helped
Answer:
Everything living would die
Answer:
Without DNA, cells could not reproduce, which would mean extinction of the species. Normally, the nucleus makes copies of chromosomal DNA, then segments of DNA recombine, and next the chromosomes divide twice, forming four haploid egg or sperm cells.
Explanation: GOOGLE
B:Fever increases body temperature and speeds up the body's reaction to pathogens.
C:Phagocytes identify cells invaded by pathogens and mark them for destruction.
D:Mucus traps pathogens and destroys them before they can enter the body.
Hey there! I took the test, and I can confirm that A. Cytotoxic T cells are activated and destroy cells that pathogens have invaded. is the correct answer
God bless ❤️
