A book contains letters, just like the DNA. It's how the letters are arranged-into words in a book- that makes them mean anything. The same is true of DNA bases. It is how they are arranged that makes them significant.

DNA is like a book because the arrangement of nucleotides in the DNA determines the entire organism’s phenotype.

Further Explanation:

Gene is defined as the linear sequence of the nucleotides that are mainly encoded for a protein having a particular function. The alleles are defined as the variant type of the gene. DNA is mainly made up of the nucleotides and also contains genetic information in the genes. Every nucleotide mainly comprised of the phosphate group, deoxyribose, and nitrogenous base. DNA is mainly composed of four distinct types of nitrogenous base:

Cytosine
Adenine
Guanine
Thymine

The letters in the book are similar to the nucleotide in the DNA. The meaningful combination of letters forms the information that is entitled. Similarly, the arrangement of nucleotides in the DNA is responsible for the structural and functional behavior of the organism. That’s why DNA is considered as a book that enclosed all the genetic information of the body.

Which is part of the spindle apparatus?

professor190 [17]

Chromatin is a part of the spindle apparatus

Explanation:

Chromosome is not only responsible for genetic material. Chromatin is that substance which consists of protein and DNA. Here DNA carries genetic instruction. Histones are main proteins of chromatin. It is also called the packaging of element for the DNA.

In two forms chromatin exist. One is euchromatin and another is heterochromatin. Euchromatin is less condensed and it can be transcribed. Heterochromatin is highly condensed and typically not transcribed. Chromosomal pathway regulates spindle assembly.
