References Chapter 1: Problems Studies of existing cells to determine the minimum number of genes for a living cell have suggested that 206 genes are sufficient. If the ratio of protein-coding genes is the same in this minimal organism as the genes of Escherichia coli (0.980), how many proteins are represented in these 206 genes.

201.88 ≈ 202.

Explanation:

Genes are the functional segment of DNA that are responsible for the phenotype and genotype of the organisms. Different number of genes are present in different organisms.

The number of the genes that are sufficient in the living cell is 206.

The ratio of protein-coding genes in Escherichia coli is 0.98.

Number of proteins = No. of genes × Ratio of protein coding genes.

Number of protein = 206 × 0.98

Number of protein=201.88 ≈ 202.

Thus, the answer is 201.88 ≈ 202.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
