Answer;
a segment of chromosomal DNA
Explanation;
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell.

With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
Answer:
UAGCAGUUAGUUUU
Explanation:
The sequence matches up with the corresponding bases. Because it is RNA A goes with U not T but T still goes with A.
A T
U A
The Golgi bodies are the empty structure in the cytoplasm. The Golgi apparatus or Golgi complex is found in most cells. It is another packaging organelle like the endoplasmic reticulum<span> (ER). It was named after Camillo Golgi, an Italian biologist. It is pronounced GOL-JI in the same way you would say squee-gie, as soft a "G" sound. While layers of membranes may look like the rough ER, they have a very different function.
