Answer: Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein. ... And when the amino acids of a protein stay the same, researchers believed, so do its structure and function.
The answer for this problem is B
Answer:
NO
Explanation:
Sunlight is an electro-magnetic wave not a substance therefore it does not have a chemical compound
The structure of the rye chloroplast DNA, which contains psbC gene coding for 43-kDa chlorophyll(a)-binding subunit of photosystem II, is determined. The sequence of trnS (UGA) gene encoding tRNA Ser is located at a distance of 140 bp downstream from the stop codon of psbC gene on the opposite DNA strand. The 5'-terminal part of psbC gene, like in other plants, overlaps by 50 bp the 3'-terminal region of psbD gene coding for D2 protein of photosystem II. The amino acid sequence of the psbC gene product reveals common features with the structure of the psbB gene product (CPa-1 protein). The structural similarity of these two proteins seems to reflect their similar functions.
