All the proteins that make up the DNA in our bodies were found and named.
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
<span>A. Classical Conditioning
Little Albert was initially exposed to a variety of stimuli and displayed no fear towards them.
In the next step of the experiment, when Little Albert was again exposed to a rat, the experimenters hit a pipe to make a loud noise, causing Little Albert to cry. This pairing of the stimuli of loud noise and rat was continued repeatedly. After enough repetitions, Little Albert began to cry just by seeing the rat.
The experiment involved the unconditioned and conditioned stimuli and responses of classical conditioning.
Unconditioned stimulus: loud noise
Unconditioned response: fear
Conditioned stimulus: rat
Conditioned response: fear</span>
