What structure is present in eukaryotes but not in prokaryotes?
dna
How many more years were prokaryotes present before eukaryotes?
Prokaryotes were present for about 2 billion years before eukaryotes emerged. Eukaryotes are believed to have evolved around 1.5 to 2 billion years ago, while prokaryotes first appeared around 3.8 billion years ago.
To what kingdom did the first eukaryotes most likely belong?
The first eukaryotes are most likely to belong to the Protista kingdom. These are mostly multicellular organisms with the earlier ones including organisms like Kneallhazia solenopsae and many more.
Why are most mutations in eukaryotes recessive?
Most mutations in eukaryotes are recessive because for a mutation to be expressed phenotypically, it typically needs to be present in a homozygous state. In a heterozygous individual, the presence of one normal allele usually masks the effects of the mutated allele, leading to a recessive trait.
What Kingdom first developed a nucleus?
Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.

What is the present tense of feature?
Feature is the present tense. The past tense is featured.
What is the dna in eukaryote?
Eukaryotes have well defiened cell organali and are bounded by membranes. The DNA in eukaryotes are packed in form of chromosomes which are present in nucleous.
Eukaryotic DNA is located in the what?
Eukaryotes have well defiened cell organali and are bounded by membranes. The DNA in eukaryotes are packed in form of chromosomes which are present in nucleous.
Is the plastid in prokaryote or eukaryote?
Plastids are organelles and are present in eukaryotes,in plant cells.
Does eukaryote have mitochondria present?
Mitochondria is a membrane bound organell.It is found only in eukaryotes.
In what locations can proteasome be located?
Proteasomes are protein complexes. These protein complexes are present in eukaryotes, some bacteria and in archaea. The proteasomes are located in the nucleus and the cytoplasm when looking at eukaryotes.
What comes between first eukaryotes and first terrestrial eukaryotes on a timeline?
The first eukaryotes were unicellular organisms that evolved around 2 billion years ago, followed by the first terrestrial eukaryotes that emerged around 1.6 billion years ago. Between these events, there were significant biological and environmental changes, including the development of multicellularity and adaptations for life on land.
What are the similarities and difference between prokaryotic and eukaryote?
Prokaryotes are most primitive organisms. All bacteria belong to thiscategory. Eukaryotes are well developed organisms. All animals and Plants including Fungi, Amoeba, Malarial parasite etc belongs to this class. Prokaryotes have single chromosome in there nucleus but eukaryotes have have multiple chromosomes in there nucleus. Prokaryotes do not have His-tone protein present in there Chromosomes. While it is present in Eukaryotes. Nucleolus is absent in bacteria but present in eukaryotes. Nuclearmembrane is absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Cellorganellesare absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Mitochondria are absent in Prokaryotes and present in Eukaryotes. 70S Ribosomes are present in Prokaryotes and 80S and Ribosomes are present in Eukaryotes. Bacteria have cell wall made up of Peptidoglycan (usually.) but plant cell wall is made of cellulose and animal cell do not have it. (pressure inside the gram positive bacteria are 30 times more than atmospheric pressure and that in gram negative bacteria is 5 times more. Itprobablyindicates that gram positive bacteria has originated in deep sea and gram negative in upper part of sea, where pressure is low.
What do eukaryotes lack?
Eukaryotes lack a cell wall made of peptidoglycan, which is present in prokaryotic cells. Additionally, some eukaryotes lack flagella or cilia for motility, which are common in prokaryotic cells.
What is the difference between prokaryotics and eukaryotics?
Major difference, Prokaryotes have no cell nucleus and eukaryotics do. Prokaryotes have been present before eukaryotes. Eukaryotes are thought to have evolved from prokaryotes throught the process of endosymbiosis.
