Why Is Kingdom Protista So Diverse? Kingdom Protista is said to be the most diverse kingdom, because each of its members are so individual from each other. If an organism does not belong any particular kingdom, it goes into kingdom Protista. This miscellanous grouping causes the organisms in the kingdom to be very different from
Why Is Modification Of MRNA Done In Eukaryotes? This modification further protects the pre-mRNA from degradation and signals the export of the cellular factors that the transcript needs to the cytoplasm. Why must mRNA be edited? RNA editing in mRNAs effectively alters the amino acid sequence of the encoded protein so that it differs from
Which Of The Following States That All Organisms Are Composed Of Cells? The unified cell theory states that all living things are composed of one or more cells. Cells are the basic unit of life. Another part of the cell theory is that all cells come from pre existing cells. What are all living cells
Where Does DNA Replication Take Place In Bacteria? In bacteria, the initiation of replication occurs at the origin of replication, where supercoiled DNA is unwound by DNA gyrase, made single-stranded by helicase, and bound by single-stranded binding protein to maintain its single-stranded state. Where does DNA replication occur in a bacterial cell? DNA replication occurs
Are Protists Eukaryotic? Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes. Why are protists considered eukaryotes? Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very
Are Prokaryotes Older Than Eukaryotes? Prokaryotes have existed on Earth since at least 3.8 billion years ago. Eukaryotes are organisms with a nucleus. The oldest evidence of eukaryotes is from 2.7 billion years ago. What came first prokaryotes or eukaryotes? The first, simplest life forms were prokaryotes—organisms, like bacteria, that don’t have a nucleus. Prokaryotes
Do Prokaryotes Have A Nucleus Yes Or No? Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes. Do prokaryotic and eukaryotic cells have a nucleus? The primary distinction
How Are Bacteria Prokaryotes Different From Eukaryotes? The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. … In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus. What are two features that distinguish
Who Gave 6 Kingdom? Six Kingdoms may refer to: In biology, a scheme of classifying organisms into six kingdoms: Proposed by Carl Woese et al: Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria. Who gave the 8 kingdom classification? E. Euarchaea and Protista. Hint: The eight kingdom system of classification was given by Thomas Cavalier-Smith. The
How Is DNA Like A Sentence? These four letters are combined into three-letter words. The words make up “genes,” which are like sentences. Each sentence has an important meaning or story to tell. How is a strand of DNA like a sentence? A strand of DNA is much like an extremely long sentence that uses
