Describe the relationship between DNA, chromosomes, and genes,

Biology
1 answer:
damaskus [11]3 years ago
6 0

Explanation:

A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes.

A gene is a molecular unit of heredity. Each gene codes for a polypeptide, which becomes a protein that performs a function in a living thing. The DNA molecules are very long and in order to fit inside the nucleus of a cell, they are highly coiled and condensed. During sexual reproduction, one haploid set of chromosomes is given to the offspring from each parent, forming a diploid amount of chromosomes in the offspring.

Since chromosomes contain all of our genes, an organism that reproduces sexually gets a combination of genes from both parents. Genes that are expressed produce an organism's phenotype.

An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.
