I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.

During translation, the tRNA molecule carrying the correct amino acid corresponding to its anticodon sequence must base pair wit

katovenus [111]

Answer:

The tRNA would be unable to read the mRNA CODON, and will be unable to carry its corresponding amino acid

Explanation:

Protein synthesis occurs in two major stages; transcription and translation. Transcription involves the synthesis of a mRNA molecule while translation involves reading the sequence of the mRNA in order to synthesize amino acids that forms protein. Let's look at translation in details. Translation occurs with the help of a type of RNA molecule called transfer RNA (tRNA) present in the RIBOSOME (site of protein synthesis).

The tRNA possesses a group of three nucleotides called ANTICODON, which it uses to read the mRNA codon that is complementary to it i.e. an anticodon UAC will read mRNA codon AUG. The tRNA binds to the mRNA molecule in order to assess its nuceleotide sequence. Once, a complementary anticodon succesfully reads a particular mRNA codon, it carries the amino acid encoded by the mRNA codon it reads to the growing polypeptide chain. This is the normal translation process.

However, as stated in the question, that if a wrong anticidon successfully binds to a codon. This means that the anticodon that binds to the mRNA codon is not complementary to it. What would happen in this case is that the Anticodon will be unable to read that particular codon it binds to because the complementary base pairing rule is used to read i.e. A-U, G-C. Once, the anticodon cannot read the mRNA codon, the tRNA will also be unable to carry the amino acid that is encoded by that CODON.

Which sequence best represents the relationship between DNA and the traits of an organism? A.DNA-mRNA-Protein-Amino Acid-Trait B

andrezito [222]

Answer:

D.DNA-mRNA-Amino Acid-Protein-Trait

Explanation:

The relationship between DNA and the trait of an organism involves a process called GENE EXPRESSION. DNA is a molecule that contains information needed for the survival of an organism. However, this information must be expressed in order to be used.

The process of gene expression involves two major processes namely: transcription and translation. Transcription involves the synthesis of mRNA from DNA template while translation involves the synthesis of amino acid sequence from mRNA. The amino acid sequence encodes PROTEIN, which determines the TRAIT of an organism.

Based on this explanation, the correct sequence that best represents the relationship between DNA and the traits of an organism is: DNA-mRNA-Amino Acid-Protein-Trait
