<h2>Answer:</h2>
Salivary amylase breaks the chemical bonds of starch to form sugar monomers.
<h3>Explanation:</h3>
- Amylase is one of the digestive enzymes which catalyze the breakdown of starch molecules into its monomers.
- A starch molecule is made of the Glucose molecules which are bonded with each other with glycosidic linkages.
- Salivary glands secrete saliva into the mouth cavity.
- Saliva contains amylase for the digestion of starch are known as salivary amylase.
- Steps in the digestion of sugars start from the action of this enzyme.
Answer: Genetic variability is beneficial for the survival and adaptation. But a flaw in DNA Replication Control or check may leads to the death of cell or may contribute in the disease or cancer.
Explanation:
Almost every species comes with the diversified collection of genes (genome). And some of the diversity comes from the spontaneous mutation but it occurs on a very low frequency. The genes either express constitutively or occasionally for an important task like genes responsible in the generation of ATP by glycolysis, tricarboxylic acid cycle, electron transport chain etc. While some of the genes are inducible that is only activated in a response to an external stimuli. Genetic variations in inducible genes might account for the adaptability or negligible change in a species genetic expression but genetic variation in constitutive or house keeping genes leads to cancer cell formation or even cell death. like mutation occur in p53 genes dysregulate the cell cycle or mutation occur in DNA polymerase enzyme that is responsible for the incorporation of NTPs (nucleotide tri-phosphates) according to wobble base pairing rule in order to make a complementary new strand from the old or parent strand, will eventually leads to cause mutations ultimately results in cell death or cancerous cell formation.
You can mix them by the same thing of generic
Three questions that focuses on the cause and effect relationship between the genetic code and gene expression, mechanisms of gene regulation and/or the role of DNA segments that is not involved in coding the proteins are:
i. Illustrate the process of translation and explain it with the help of a diagram.
ii. What are codons? Name the stop codons in eukaryotes.
iii. What are exons and introns? Explain what happens to the introns during the process of transcription and translation?
I think A. It’s the only one that’s really makes since for this question.
