A gene is a segment of DNA, a condensed DNA molecule makes up a chromosome, a chromosome is inside a nucleus, and a nucleus is contained within a cell. A DNA molecule is a segment of a gene, a gene makes up a chromosome, a chromosome is inside a cell, and a cell is contained within a nucleus. A gene is a segment of a chromosome, a condensed chromosome makes up a DNA molecule, a DNA molecule is inside a nucleus, and a nucleus is contained within a cell. A DNA molecule is a segment of a chromosome, a chromosome makes up a gene, a gene is inside a cell, and a cell is contained within a nucleus.
Answers
The statement “A gene is a segment of DNA, a condensed DNA molecule makes up a chromosome, a chromosome is inside a nucleus, and a nucleus is contained within a cell” is the best suited one among the others.
1. The genetic code is scripted on DNA in a sequence of nucleotides.
2. These DNA strands have coding and non-coding regions.
3. A set of coding and non coding regions with functional importance of protein production are called genes.
4. The DNA strand looks like a chain of beads coiled around in a form of cylinder called Solenoid structure.
5. This further gets tightly coiled along with few proteins to form a structure called chromatin.
6. This chromatin further gets packed into the further condensed form with the help of Histone proteins this forms a Scaffold structure.
7. Apart from the proteins that are involved in packing of DNA, proteins required for the gene expression and DNA repair are also form a part of chromosomes.
8. During the mitotic phase of the cell division these structures form into chromosomes and the genetic information get equally distributed between the two daughter cells.
Answer:
The correct answer is A.
Explanation:
A gene is a segment of DNA, a condensed DNA molecule makes up a chromosome, a chromosome is inside a nucleus, and a nucleus is contained within a cell.
