Double-stranded DNA loops around 8 histones twice, forming the nucleosome, which is the building block of chromatin packaging. DNA can be further packaged by forming coils of nucleosomes, called chromatin fibers. These fibers are condensed into chromosomes during mitosis, or the process of cell division.
So, your answer is A
Answer:
Two true-breeding stocks of pea plants are crossed. One parent has red axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower color and location assort independently.
Explanation:
If 1,000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers=190
Among the F2 offspring, what is the probability of plants with white axial flowers=3/16
Answer:
Two phenotypes.
Explanation:
When there is a single gene trait and it shows a simple dominant-recessive pattern then it will result in two phenotypes. As the name suggests, a single gene trait is a trait which is controlled by only one gene.
For example, consider a trait Tallness which is a single gene trait and the two alleles for this gene are T and t where T is dominant and t is recessive. The different phenotypes in different allelic combinations has been shown below -
TT - Tall
Tt - Tall
tt - dwarf
Thus we see here that only two phenotypes Tall and dwarf are present for the all possible genotypes.

Answer: The complementary strand will be TGCAGCT.
Explanation:
Replication is a process of making identical copies of a DNA in the cell. It is a process by which the genetic information in a parent DNA is used to make two identical copies of DNA (daughter DNA) which are complementary to the parent DNA. Four bases are found in DNAs: Thymine, Adenine, Cytosine and Guanine. In forming the complementary strand, the bases in the parent strand pairs with appropriate bases. In base pairing, Adenine pairs with Thymine while Guanine pairs with Cytosine.
A= T while G = C.
