Answer:
In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein
Explanation:
Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.
Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense (i.e. warmer) and rises. The cooler air from the land moves in to take its place. Sea breeze: Sea breeze blows during the day and the land heats up faster than the sea
Answer:
46
Explanation:
in mitosis it doubles to 92
NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.
Explanation:
Answer:
All the organisms of one kind in an ecosystem are called a population. For example, a pond ecosystem might have populations of frogs, waterlilies, insects, duckweed, and protists. Populations living and interacting with each other form a community.
