Nitrogenous bases are located on both strands of the DNA double helix. What is the significance of the nitrogenous bases? * The order of nitrogenous bases determines the ordeer of amino acids in the proteins synthesized The number of Adenines and Cytosines determines the type of RNA that will be produced The type of hydrogen bonding between the nitrogenous bases determines which amino acid will be added to the peptide chain The amount of Thymine and Guanine in the DNA molecules determine the length of the genes

The significance of the nitrogenous bases in the DNA is such that their order determines the order of amino acids in the proteins synthesized.

The order of the nitrogenous bases in a DNA strand will determine the order of the genetic codes in a mRNA transcribed from such a DNA.

Each genetic code represents an amino acid. Thus, the order of the bases will ultimately determine the order of the amino acids in the protein generated during translations.

The order of nitrogenous bases determines the order of amino acids in the proteins synthesized

Explanation: The nucleotide sequence on the DNA strand determines the amino acid sequence of the protein synthesized.

A DNA is first copied into an mRNA in a process known as transcription. Transcription occurs in the nucleus and it is catalyzed by an enzyme RNA polymerase.

The mRNA then moves to the ribosome where it is copied into an amino acid sequence of a protein. The nucleotide sequence on the mRNA are arranged in triplets known as codons. Codons are triplet of nucleotide that code for amino acid. The codons on the mRNA are read by the ribosome and used to make a protein.

Therefore, the order of nitrogenous bases determines the order of amino acid sequence of the protein synthesized.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
