Answer:
The formula for calculating population density is Dp= N/A. In this equation, Dp is the density of population, N is the total population as a number of people, and A is the land area covered by that population.
Explanation:
a statistic that tells you how many people live in a certain area. ... density is reported in square miles or kilometers, and may or may not include bodies of water. This type of measurement is called arithmetic density, and is reported as the total number of people per land.
Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
The hypothalamus controls the secretions of the pituitary gland
Answer:
codon
Explanation:
As in the DNA, the mRNA which contains the genetic information is in sequence of the nucleotides, <u>that are arranged into the codons which consists of three base pairs each.</u>
<u>Codon with three base pairs encodes for a specific amino acid (except stop codons). </u>
The process of the translation of the codons into the amino acids requires two types of RNA which are:
Transfer RNA (tRNA) : It is the RNA which mediates the recognition of codon and provides corresponding amino acid.
Ribosomal RNA (rRNA): It is the RNA which is the central component of ribosome's protein.
