A change occurs in one nucleotide of a triplet within a protein-coding portion of a gene. This change results in a new triplet that codes for a stop codon. What is this mutation called? - -Nonsense mutation A point mutation occurs in which a single nucleotide change results in a codon that codes for a different amino acid. What is this mutation called? - -Missense mutation A single nucleotide is changed. What is this mutation called? - -Point mutation A point mutation occurs in which a sin...

TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

A change occurs in one nucleotide of a triplet within a protein-coding portion of a gene. This change results in a new triplet that codes for a stop codon. What is this mutation called? Nonsense mutation A point mutation occurs in which a single nucleotide change results in a codon that codes for a different amino acid. What is this mutation called? Missense mutation A single nucleotide is changed. What is this mutation called? Point mutation A point mutation occurs in wh...

Most of the cell membrane's specific functions are controlled by: - Proteins Alcoholic Fermentation is a form of: - Anaerobic Respiration Phagocytosis is a form of: - Endocytosis What is a pyruvate? - Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. What are the small spher...
