Answer:
It is most likely formed underground
Explanation:
Chemosynthesis is the biological conversion of one or more carbon- containing molecules.
Probiotics are healthy bacteria which live in the human body, in particular in the intestines, and help fight disease. They are living microorganisms which, when ingested, have beneficial effects on the human body. The most common form of probiotic is Lactobacillus Acidophilus.
It is estimated that there are several trillion friendly bacteria comprising over four hundred species in the average human gastrointestinal tract. By body weight, each of us carries around approximately four pounds of intestinal microflora!
They counteract damage done to the body due to antibiotic use and stimulates the immune system to function better when you are relatively healthy, but when you’re sick, they can also contribute significantly to relief of health problems ranging from indigestion and diarrhea to colon and liver cancer.
Lactobacillus Acidophilus is also involved in the production of B vitamins (niacin, folic acid, and pyridoxine) during the digestive process.
Some of the ways probiotics appear to improve health include: alleviating lactose intolerance, reducing and preventing diarrhea, defending against infections, enhancing the immune system, reducing inflammation, preventing allergic reactions, and reducing chronic constipation
Answer:
4. c. Deletion/ frameshift mutation
5. a. Tyr Tyr Asp Ser Gly
6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.
Explanation:
4)
A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.
5)
The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly
6)
The wild type DNA sequence is:
5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
The mutant i.e. mRNA with the added G will be
5'
ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.
