1billion kilometers nice question by the way
Answer:
b. False
Explanation:
Kozak consensus sequence acts as translation initiation site and is involved in the initiation of translation process.
The sequence is 5'-(gcc)gccRccAUGG-3' . AUG in the sequence is start codon and codes for methionine. It is highly conserved. R denotes a purine which means that it can be either adenine or guanine. Significance of bases inside brackets have not been properly confirmed.
Hence, the statement that Kozak consensus sequence defines the location of the transcriptional start site is false.
The answer would be: C - The introduction of an invasive predator that preys on the brightest-colored individuals in the lizard population.
Answer:
Part A: False
Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic
Explanation:
The Ames test, also known as <em>Salmonella typhimurium</em> reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).
