<span>Tertiary</span> structure - three-dimentional structure of one polypetide chain.

Proteins are considered as for their conformation in four different stages:

Primary structure is referred solely to the sequence of amino acids<span> in the polypeptide chain.
</span>Secondary structure is the immediate basic folding of a protein and it can be α-helix and β-sheets.
Tertiary structure is the three-dimentional folding of a singles polypetide.
Quaternary structure is the thee-dimenional structure that results from the combination of two or more individual polypetides working as single protein.

Compare and contrast the structure and function of DNA and RNA.
Ratling [72]

Answer:

DNA has a double- helix structure which means it has two strands. The DNA strands are made from sugar (Deoxyribonucleic), phosphates and nitrogenous bases. There are 4 nitrogenous bases, 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. The pyrimidine bases are Thymine and Cytosine. DNA gives our genes.

RNA is a single strand unlike DNA. The strands are made from sugar (ribonucleic), phosphate and the nitrogenous bases. There are 4 nitrogenous bases 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. However, the 2 pyrimidine bases are Uracil and Cytosine. The function of RNA is to contribute to releasing proteins based on our rRNA and tRNA and mRNA. This process is known as RNA and transcription.

Which of the following best describes how genes produce traits in an organism? A. Genes are produced by chromosomes during trans
Vaselesa [24]
The correct answer is D. The genes are coded to produce specific proteins, by the process of transcription and translation.
These proteins then, lead to the production of characteristic traits like eye color, hair color etc. 
So genes indirectly control the traits

Study the following statements, which compare the method of fermentation preferred by yeasts to they type of fermentation that m
Volgvan

Answer:

Only one of the three statement is true; and that is,

(ii.) Different metabolic end products result from the two types of fermentation

Explanation:

Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.

Fermentation is carried out by many organisms including man.

In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.

In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.

From the options provided in the questions, the correct option is:

Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.
