Answer:
secondary structure ... hydrogen bonds...
Explanation: Some regions of a polypeptide may coil or fold back on themselves. This is called secondary structure, and the coils or folds are held in place by hydrogen bonds.
The correct statement is D. APICAL MERISTEMS ARE SOMETIMES CHANGED INTO FLORAL MERISTEMS.
Apical Meristems are found in the tips of the roots and in the buds of the shoots. They supply cells for the plants to grow in length.
Apical Meristems are found in herbaceous plants, woody plants, grasses, and flowering plants.
In flowering plants, shoot apical meristem develops into an inflorescence meristem which produces the floral meristem. The floral meristem is responsible for the production of the sepals, petals, stamens, and carpels of the flower.
The best answer is D.
Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.
In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached mRNA is decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.
