Frequent question: Does the number of chromosomes determine the complexity of an organism explain?

Is chromosomes number a good predictor of organism complexity explain?

The answer is no. The chromosome number is not correlated to the complexity of an organism. … It is because larger chromosomes contain more genes than the number of genes found in the smaller ones. If there are more genes that contain coding or instructions for a particular trait, then an organism is more complex.

Does the number of genes determine the complexity of an organism?

Even so, genome size and the number of genes present in an organism reveal little about that organism’s complexity (Figure 1). Figure 1: Chromatin has highly complex structure with several levels of organization. The simplest level is the double-helical structure of DNA.

Do chromosomes mean more complex?

Does the number of chromosomes determine the complexity of the organism? Answer 1: No, the number of chromosomes is actually barely related to complexity at all. For instance, humans have 46 chromosomes (2 sets of 23) whereas small deer have 6 chromosomes, and carp have over 100.

What is more complex DNA or chromosomes?

The same thing is true with your chromosomes except instead of pages, they are made up of DNA. More DNA does not mean more complexity. You have just over three billion base pairs of DNA (base pairs are just one way to measure the amount of DNA).

What makes the complexities of an animal as an organism?

Animals vary in complexity and are classified based on anatomy, morphology, genetic makeup, and evolutionary history. All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue.

Why do organisms have different numbers of chromosomes?

Species (and individuals) are unique because of the content of the DNA that makes up the chromosomes, not the number of chromosomes. As you may already know, chromosomes are made of tightly packed DNA, and DNA is made of incredibly long strands of chemicals called nucleotides.

How are the complexity of an organism and the number of genes in its genome related quizlet?

The complexity of an organism is proportional to the number of genes in its genome. Only 2.5% of the human genome actually codes for proteins.

Which gene structure is more complex?

Eukaryotic gene expression is more complex than prokaryotic gene expression because the processes of transcription and translation are physically separated. Unlike prokaryotic cells, eukaryotic cells can regulate gene expression at many different levels.

What has the most complex DNA?

According to the Johns Hopkins scientists, bread wheat has one of the most complex genomes known to science, containing an estimated 16 billion base pairs of DNA and six copies of seven chromosomes.
