In the list of four terms below, which term is the second most inclusive.?
a. | Genome |
b. | Allele |
c | Chromosoe |
d | Gene |
Introduction:
Cells of living organisms contain genetic material that determines the whole composition of an organism. Genetic material is present in the nucleus of the eukaryotic cells. This hereditary material is inherited by offspring from their parent. Genetic material in prokaryotes is contained in a central area of the cell known as the nucleoid, which is not enclosed by a nuclear membrane.
Answer to Problem 1MCQ
Correct answer:
A chromosome contains the folds of deoxyribonucleotide (DNA) sequence. Gene and allele are small hereditary units located in a chromosome. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
Option c. is given as, “Chromosome.”
A chromosome is a hereditary unit that consists of long strands of deoxyribonucleotide coiled up with the various type of proteins. It is considered as the second most inclusive term after the genome because chromosomes represent the subset of the genome.
Reason for incorrect answers:
Option a. is given as, “Genome.”
Genome is the whole genetic content of an organism. Genome is the collection of the entire DNA present in the cells of an organism. Genome is considered the most inclusive because it encompasses all the genetic information of a cell. Hence, option a. is incorrect.
Option b. is given as, “Allele.”
An allele refers to a variant of a gene that is present on the same loci of a chromosome. New alleles arise due to different mutations. Hence, option b. is incorrect.
Option d. is given as,“Gene.”
Gene is the small hereditary units present on a chromosome that determines the inherited characters. A gene is a portion of deoxyribonucleotide (DNA). Hence, option d. is incorrect.
Hence, the options a., b., and d. are incorrect.
A chromosome is the second inclusive term among genome, allele, and gene. Thus, the correct answer is option c.
