Answer:
Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.
Explanation:
DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.
Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.
Thus, the correct answer is option (b).
An organelle is any number of organized structures inside a cell
Answer:
plants need protein for healthy growth and development. One of the critical roles of protein in plants is regulating phototropism and mediating the response of plants to light-dark cycles. Proteins are also involved in energy-generating reactions, intracellular structure and membrane transport.
Explanation:
A nucleotide is made up of a base, a sugar and a phosphate group.
Answer:
There is a basic observation that similar sequences from the same evolutionary family often adopt similar protein structures, which forms the foundation of homology modeling. So far it is the most accurate way to predict protein structure by taking its homologous structure in PDB as template.
