Which is smallest gene or 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 largest DNA gene or chromosome?
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.
What is a chromosome compared to DNA?
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Are proteins bigger than DNA?
DNA contains the genetic information of all living organisms. Proteins are large molecules made up by 20 small molecules called amino acids. All living organisms have the same 20 amino acids, but they are arranged in different ways and this determines the different function for each protein.
How much DNA is in a single cell?
A human cell contains about 6 pg of DNA.
How much DNA is in the human body?
The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.
