The correct answer is D) The codon AUG must be identified.
What must occur for protein translation to begin is that the codon AUG must be identified.
The process starts when the 5AUG or start codon is identified. In the polypeptide chain, the 5AUG is the first amino acid. We are talking about Transition, the process when the genetic code in an RNA molecule has to be decoded in a polypeptide chain in order to deliver an amino acid sequence. In this complex transition system, there are important components included such as ribosomes, transfer RNA, and mRNA.
Answer:
Radiation from the lamp reaches the soil and causes the soil to warm.
Answer: Polyphyletic
Explanation: The kingdom Protista is considered Polyphyletic because their taxa do not share a common descendant that is many are developed by from many ancestral lineage. Protists are difficult to classify. They may be unicellular, colonial or multicellular. Polyphyletic groups mess up organizational systems.
As eukaryotes, protists can have many diverse organelles which includes a nucleus, mitochondria, contractile vacuoles, eyespots, plastids, pellicles, and flagella. The protists nuclei consist of chromosomes, with DNA linked with proteins. Protists can undergo sexual and asexual reproduction, meiosis, and mitosis. Protists can be free-living, or live symbiotically with another organism. This symbiosis can be mutual or parasitic. Many protists are economically beneficial to humans, while several others can cause fatal diseases. Protists make up the most of the planktons in aquatic life, where they areas the primary producer of the food chain. Many protists are motile using cilia, flagella, or pseudopodia (false feet) to move, while others are sessile( non-motile). They may be producing their own food from sunlight (autotrophs) or using a outside source of nutrition from outside (heterotrophs) . Researchers are currently comparing the RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) sequences of the protists with that of plants and animals, but no conclusive evidence has been reached. It is unknown to many researchers whether protists were the precursors to plants, animals or fungi or bacteria.
Answer:
Osmosis is a process in which molecules pass from semipermeable membrane.
Explanation:
Osmosis is a biological process. The solvent molecules pass through semipermeable membrane and then solute particles move through the membrane with the help of water. These molecules are not capable of passing through the membrane in absence of water.
