Is a gene bigger than a chromosome?
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.
What is the largest chromosome gene 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.
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.
Is a gene bigger than DNA?
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
How many genes are in a chromosome?
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.
What is the correct order of genetic material from smallest to largest?
The correct answer: According to the order from smallest to largest, the order will be: Nucleotide, Gene, DNA, Chromatin, Chromatid, Chromosome.
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.
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.
Which is larger chromatin or DNA?
Thus, within the nucleus, histones provide the energy (mainly in the form of electrostatic interactions) to fold DNA. As a result, chromatin can be packaged into a much smaller volume than DNA alone.
