The atmosphere had no oxygen it thereby created an environment where only anaerobic organisms could exist. They couldn't make there own food due to lake of oxygen in the atmosphere
Explanation: During the archaea period 3.4 billion years ago after amino acids develop the first living cells the prokaryotes with no nuclei , simple design and no organelles. According to Miller Urey and Sagan these cells were anaerobic as no oxygen was present in atmosphere and they were heterotrophs using fermentation as the process to obtain energy from the molecules formed by the heat and light in early atmosphere this is why these organisms are said to be anaerobic and heterotrophs
Between prokaryotes and eukaryotes, which type of cells are believed to have evolved first? Scientists have concluded that prokaryote life forms preceded the more complex eukaryotes. All organisms on Earth are classified into two basic cell types. Kary means nucleus.
The nucleotide sequence on a section of
DNA where transcription begins is called a promoter.
To add, i genetics, a promoter is a region
of DNA that initiates transcription of a particular gene. Promoters are found along
the transcription beginning sites of genes, on the same strand and upstream on
the <span>DNA.</span>
There are multiple differences between eukaryotic and prokaryotic cells for example: No membrane bound organelles in prokaryotes. Single circular chromosome in prokaryotes, multiple linear chromosomes in eukaryotes. Most prokaryotes are haploid while most eukaryotes are diploid.
