This arrest of division is an example of Density-dependent inhibition. Density dependent inhibition is the process where crowded cells stop dividing; the number of cells in an area force competition for nutrients, space, and growth factors, therefore, when cells are crowded, they get signals to stop dividing. In density dependent inhibition, when density is high there is no cell division and when the density is low cells divide.
Chromosomes from different parents determines the genetic structure of the child (from both parents) only with recessive genes ONLY becoming apparent if they are present in BOTH parents<span />
Answer:
48 amino acids
Explanation:
The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.
It adds bases in only one direction.
