Answer:

1. The true statement about the relationship between an organism's traits and its genes is that genes encode the proteins that determine an organism's traits (option B).

2. A DNA mutation can cause the structure of the protein to be changed (option C).

Explanation:

DNA contains the genetic information necessary for the structure and function of living beings. It is a molecule that, once transcribed into mRNA, dictates the rules for protein synthesis.

1. Chromosomes are composed of a DNA molecule, whose segments form the genes that contain specific base sequences to determine a trait.

The information from the DNA is transcribed into the mRNA, which is responsible for carrying it to the cytoplasm where protein synthesis occurs. These proteins formed from the genetic code determine the different traits in living beings. So, genes encode the proteins that determine an organism's traits.

2. Since the DNA contains the information needed to transcribe it into the mRNA and for the mRNA to initiate protein synthesis, any alteration in the DNA base sequence -due to mutation- can be produced:

A transcription of the mRNA with the alteration
That during mRNA translation, the codon that forms an amino acid, or that determines the stop of protein synthesis, is changed.
The alteration or change, consequently, of the synthesized protein.

There is a relationship between the DNA mutation and the structure of the protein being changed.

What molecule is responsible for carrying the acetyl group from pyruvate into the citric acid cycle?

Airida [17]

During Glycolysis, one molecule of glucose is converted into two molecules of pyruvic acid in the cytoplasm of the cell. Pyruvic acid is then moved into the inner matrix of the mitochondria, which is the organelle within the cell responsible for the generation of energy. The pyruvic acid molecule is converted into acetyl Co-A, which is the molecule that enters the Krebs Cycle. In the Krebs Cycle, acetyl Co-A is attached to oxaloacetate acid to form citric acid; the Krebs Cycle is alternately known as the citric acid cycle.

slavikrds [6]

The ribosomal RNA studies that led to the division of prokaryotic organisms into the bacteria and the archaea were begun by Woese.

Ribosomal RNA makes the maximum portion of RNA in the cells. However, it is not translated into proteins. But it plays a major role in the translation of m-RNA. They are responsible for deducing the order of the amino acid sequence and linking the amino acids together to form the polypeptide.

Archaea are a group of organisms that are similar to bacteria, yet have evolutionary differences. They are found in extreme locations like hot spring, salty water bodies, or areas where methane if formed. Therefore, they are also known as extremophiles.
