Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.
CLAP YOUR HANDS. Have a nice day lol
Answer:
1 A. amino acid
2 B. Polypeptide chain (protein)
3 C. tRNA (anit-codon)
4 D. codon
Explanation:
The whole diagram explains protein synthesis from transcription to translation.
- The codon, GGU is a codon with a triplet nature coding for glycine, and it consists of three nucleotides
- The amino acid, phenylanine is encoded from the codon, UUU found on the mRNA molecule
- transfer RNA (tRNA) helps to combines covalently with a specific amino acid, threonine and transfers the amino acid to the ribosomes to join the polypeptide chain
- polypeptide chain is a pentapeptide (with five amino acids) and is formed in the final stage of protein synthesis.
