The sequence could code for the incorrect amino acid during translation if a cytosine base is changed to a thymine base in a DNA segment during DNA replication. The right response in this case is option C.
A base substitution in a DNA sequence during replication compromises the genetic information in the area where the change took place. The base replaced is also transcribed along with the genetic information from DNA into RNA during transcription. Adenine instead of guanine is transcriptionally transcribed if cytosine is replaced with thymine.
Due to the substituted base, the incorrect amino acids may wind up being translated during the translation of the genetic instructions, resulting in a defective protein.

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.
<h3><u>Answer;</u></h3>
B.introduced species
<h3><u>Explanation;</u></h3>
- <em><u>Animals become extinct for a number of reasons. Currently many animals are endangered or have become extinct due to human activities or human influence.</u></em>
- Extinctions may be caused by reasons;<em><u> such as pollution; loss of habitat due to human activities such as agriculture, introduced species, hunting and poaching for meat and other animal products such as feathers, horns and skins, and also over-harvesting among other influences.</u></em>
- In this question; <em><u>Introduced species occupies the largest percentage, that is 39%, from the pie chart (Attached).</u></em>
- Hunting and poaching; 23 %, Habitat loss; 26%, and Others; 2%.
