Explanation:
1698 is the minimum number of nucleotides required in the coding region of the LDS2B mRNA molecule to produce and terminate the 565-amino acid polypeptide.
TWO reasons why the number of nucleotides in the mature RNA may differ from the number of base pairs in the gene are:
i) because gene contains non coding sequence also called as introns +exons while mature mRNA contains only exons.
ii) genes have promoter region while mature mRNA does not have so.
Explanation:
The minimum number of nucleotides in the coding region of a mRNA sequence or molecule is number of amino acids multiplied by three. There are triplet codon or 3 nucleotides which code for an amino acid.
number of nucleotides = number of amino acids x 3
number of nucleotides = 565 x 3
number of nucleotides= 1695 nucleotides
The stop codon would also be added as it is a part of mature RNA so
1695 + 3 = 1698
The coding region or exons carry only the nucleotides which code for amino acid polypeptide chain.
The two reasons why number of nucleotides in mature RNA and gene is different:
1) Because the gene carries both introns (non-coding regions) and exons (coding region) and mature mRNA after spicing removes the introns and has only exons which are read by the tRNA to carry amino acids in translation.
2) Genes consist of promoter region which are not transcribed hence not transferred to mRNA. Although mRNA is transcribed using the promoter region.
Answer:
Inspiration
Explanation:
Pulmonary ventilation (breathing) can be defined as the flow of air into the lungs during inhalation (i.e., inspiration) and the inverse process where the air out of the lungs during exhalation (i.e., expiration). The lungs are active during the process of inspiration, while they are passive during expiration. Inspiration happens when the intrapulmonary pressure is below the atmospheric pressure, thereby the lungs expand and air enters the lungs.
Answer:
Steam.
The burning coal warms water in a boiler, resulting in the production of steam. Steam from the boiler rotates the turbine engine's blades, converting thermal energy from the burning coal into mechanical energy that powers the turbine engine.

Answer:
The success of an individual organism in passing on its genes to the next generation is a measure of its biological success. A person's genetic information is passed down through the generations through their offspring.
