All matching codons in all organisms DNA code for the same amino acids.
Option D.
<h3><u>Explanation:</u></h3>
Codons are defined as group of three nucleotide bases that forms a triplet, and codes for a particular amino acid.
There are four nitrogen bases, so four possible nucleotides. Among them, 3 are stop codons, rest 61 are codons denoting the 20 amino acids. Codons are discrete, meaning no same codon codes for more than 1 amino acid.
And these codons are universal. It means, like AUG denotes for amino acid methionine, and that is same in bacteria, as well as in all organisms. So they are universal.
Chromosomes is the answer I think
Answer:
intracellular is the correct answer
Answer:
Sarcomere
Explanation:
A myofibril or muscle fiber under an electron microscope shows alternate light band and dark bands. These bands give the skeletal muscle and cardiac muscle a striated appearance. The light band is called the I- band or isotropic band, and the dark band is known as A- band or anisotropic band. In the center of the I-band Z-line is present. It is discovered from a German term Zwischenscheibe (between the disc). The portion of myofibril between one Z-line to the next Z-line is called sarcomere.
