Which is the largest gene chromosome or DNA?
Chromosome 1 is the largest human chromosome, spanning about 249 million DNA building blocks (base pairs) and representing approximately 8 percent of the total DNA in cells. Identifying genes on each chromosome is an active area of genetic research.
What is the order smallest to largest for nucleus DNA gene and chromosome?
The correct answer: According to the order from smallest to largest, the order will be: Nucleotide, Gene, DNA, Chromatin, Chromatid, Chromosome.
What is the smallest gene or DNA?
From smallest to largest: nucleotide, gene, chromosome, genome. Nucleotides are the smallest building blocks of DNA.
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.
Which is the correct order of structure from smallest to largest?
From smallest to largest, the order is nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell. What is the function of DNA? The function of much of the DNA in a cell is not known, but some of it encodes the cell’s RNA and proteins.
Are genes smaller than DNA?
A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are variations of the same gene.
Which is the smallest gene?
Chromosome 21 is both the smallest human autosome and chromosome, with 48 million base pairs (the building material of DNA) representing about 1.5 percent of the total DNA in cells….
| Chromosome 21 | |
|---|---|

| Features | |
| Length (bp) | 46,709,983 bp (GRCh38) |
| No. of genes | 215 (CCDS) |
Is a gene smaller than DNA?
What is the shortest gene?
mccA 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 largest gene?
The largest known gene is the human dystrophin gene, which has 79 exons spanning at least 2,300 kilobases (kb).
What is the DNA molecule from smallest to largest?
From smallest to largest: nucleotide, gene, chromosome, genome. Nucleotides are the smallest building blocks of DNA. There are four nucleotides (A, G, T, C) which arrange in pairs to form the long double strands typical of DNA molecules. A gene is a segment of DNA which codes for the amino acid sequence of a particular protein.
Is DNA bigger than genes?
No, gene is not bigger than DNA… Hereditary information found in genes which is located in the chromosomes of each cell. Chromosomes found in the nucleus of the cell that contain dna stretches called as genes. A human cell contains approx. 30,000 genes. Traits which are inherited are determined by one or many genes…
What is the smallest structure of DNA?
The smallest units of DNA are called nucleotides. These are organic molecules that serve as building blocks of DNA and RNA. They are monomers or subunits of nucleic acids like RNA and DNA.
Which is larger genes or DNA?
• Gene is a fraction of the DNA strand while chromosome is the whole strand of DNA. Therefore, it could be said that chromosomes are longer and larger than genes.
