During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs.
Arboreal
Explanation:
Arboreal Definition:
Arbor is a Latin word meaning “tree”. Thus, arboreal means “related to or pertaining to trees”. The other similar words (synonyms) include arborous, arboraceous, arborary. Arbiform is the word used for expressing the term “resembling a tree”
Arboreal Animals
Arboreal animals : are those animals that spend most of their life on trees. They feed, travel, play, and sleep on trees. They prefer to grow their young ones on the trees, which is a difficult task because the newborns are always prone to fall on the ground from height. However, they have adapted themselves in such a manner that these animals can now easily live on such heights. Examples of such animals include chameleons, lizards, green tree pythons, tree snails, koalas, squirrels, cats, monkeys, parrots, sloths, and a variety of insects. Leopards and goats are also considered arboreal because of their excellent ability to climb the trees. Leopards can carry their kills to the top of trees to avoid other predators and scavengers.
Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
