What is the size order of a gene cell chromosome and nucleus?

The correct answer: According to the order from smallest to largest, the order will be: Nucleotide, Gene, DNA, Chromatin, Chromatid, Chromosome.

What is the order in size between DNA cell chromosomes nucleus genes and human from the largest to the smallest?

From smallest to largest, the order is nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell.

Which shows the correct order of genetic material from largest to smallest?

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. Thus, the correct answer is option D i.e., Genome, Chromosome, Gene, Nucleotide.

Is nucleus bigger than cell?

He suggests that a cell nucleus will be larger than an atomic nucleus, because a cell is larger than an atom. However, he only think the cell nucleus will be about ten times the size of the atomic nucleus as he suspects the cell is only about ten times the size of an atom – after all they are both “really microscopic”.

Which is smaller nucleus or cell?

Nuclei are smaller than most eukaryotic cells, but bigger than some prokaryotic cells. Chromosomes tend to be smaller than cells or nuclei, and genes are parts of chromosomes.

What is MB in genome size?

Genome size refers to the amount of DNA contained in a haploid genome expressed either in terms of the number of base pairs, kilobases (1 kb = 1000 bp), or megabases (1 Mb = 1 000 000 bp), or as the mass of DNA in picograms (1 pg = 1012 g). … Prokaryotic genomes range from about 500 kb to about 12 Mb.

What are the 4 stages of the cell cycle?

In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.

What is a cellular nucleus?

The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. … A double-layered membrane, the nuclear envelope, separates the contents of the nucleus from the cellular cytoplasm.

Are genes 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.

What is the correct order of the genetic information in the cell?

Genome, chromosome, nucleotide, gene.

What is the order of genetic material?

Chromosome, Gene, Genome, Nucleotide.

What is the correct order of genetic levels of organization?

The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

What is the size of nucleus in a cell?

The nucleus is normally around 5-10 μm in diameter in many multicellular organisms, and the largest organelle in the cell. The smallest nuclei are approximately 1 μm in diameter and are found in yeast cells.

What determines nucleus size?

Factors that affect nuclear volume

One idea, known as the nucleoskeletal theory, is that DNA content influences the volume of the nucleus, which in turn influences the size of the cell (Cavalier-Smith, 2005; Gregory, 2005).

How large is the nucleus of a cell?

The size of the nucleus depends on the size of the cell it is contained in, with a nucleus typically occupying about 8% of the total cell volume. The nucleus is the largest organelle in animal cells. In mammalian cells, the average diameter of the nucleus is approximately 6 micrometres (µm).
