Answer:
All of the answer options are correct.
Explanation:
Chargaff contributed in understanding the structure and composition of DNA with his discoveries. He discovered that purine and pyrimidine bases are in equal amounts in a DNA molecule. He also discovered that amount of Adenine base (A) is equal to amount of Thymine base (T). It means that A pairs with T. Since A is a purine and T is a pyrimidine it also implies that purine base pairs with a pyrimidine base. This conclusion can also be arrived by taking in consideration the other base pair which is G (purine) and C (pyrimidine).
Answer:
The protein that are intake through foods are broken down in the body and is converted into nitrogenous waste products which are eliminated from the body through the process of excretion.
Explanation:
Ammonotelic-Those organisms that excrete nitrogenous waste products in the form of ammonia from the body throuh the process of excretion is called as ammonotelic animals.Ammonia is more soluble in water.
Ex- Bony fish, Octopus, Sepia etc.
Ureotelic-Those organisms that excrete nitrogenous waste products in the form of Urea from the body through the process of excretion is called as Ureotelic organisms.Urea is soluble in water.
Ex- Human.
Uricotelic-Those organisms that excrete nitrogenous waste products in the form of Uric acid from the body through the process of excretion is called as uricotelic organisms.Uric acid is insoluble in water.
Ex- Reptiles, birds etc.
Genetic translation occurs in ribosomes located in the cytoplasm of the cell.
<h3>What is Ribosome?</h3>
To execute biological protein synthesis, ribosomes, also known as Palade granules (after their discoverer George Palade and because of their granular structure), are macromolecular machinery that are present in all cells (mRNA translation). To create polypeptide chains, ribosomes combine amino acids in the order dictated by the codons of messenger RNA (mRNA) molecules.
The short and big ribosomal subunits are the two main parts of ribosomes. Each subunit is made up of numerous ribosomal proteins and one or more ribosomal RNA (rRNA) molecules (RPs or r-proteins). The translational apparatus also refers to the ribosomes and related components.
