Which is smaller gene DNA or chromosome?
From smallest to largest: nucleotide, gene, chromosome, genome. … A gene is therefore composed of many pairs of nucleotides. A chromosome is a long strand of DNA which is coiled up with various proteins. A chromosome contains many genes.
What is smaller a gene or a cell?
Gene is the basic functional and physical unit of heredity and is made up of DNA. … It is a membrane-bound structure and contains the hereditary information. A cell is the smallest functional unit of life and contains nucleus and cytoplasm in a membrane-bound structure.
Which is the smallest gene?
Thus the mccA gene encodes the peptidic chain of MccC7. To our knowledge, mccA is the smallest gene so far reported.
What is the smallest nucleus gene chromosome or cell?
The correct answer: According to the order from smallest to largest, the order will be: Nucleotide, Gene, DNA, Chromatin, Chromatid, Chromosome.
Why are chromosomes arranged from largest to smallest?
In a karyotype, chromosomes are arranged and numbered by size, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder.
How many genes does a chromosome have?
Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins. Each of the estimated 30,000 genes in the human genome makes an average of three proteins.
Is a genome smaller than a gene?
Both of these are essential bio molecules within all life-forms on Earth. Nucleotides come after genes. From the above explanation it is clear that the series of organisation of genetic material from largest to smallest is Genome, Chromosome, Gene, Nucleotide which is given in the option D.
Is a codon smaller than a gene?
From smallest to largest, the order is nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell. … RNA nucleotides contain a sugar called ribose; DNA nucleotides contain a similar sugar called deoxyribose.
