Answer:
A
Explanation:
ECM proteins are significant in the development of the extracellular matrix which is responsible for supporting and connecting cells together in the formation of tissues. The extracellular matrix is also a major component of connective tissue that is composed of collagen fibers connecting tissues. Mutations of these proteins will result in connective tissue disorders such as scurvy, sarcomas, systemic lupus erythematosus (SLE) and etcetera.
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.
