which codon in the sickle cell DNA is altered: 1st , 2nd or 3rd
Answers
Answer:
Mutation in one exon: 1 amino acid will be replaced by another one; variable consequences depending on the amino acid: most of the time a silent mutation; but the Sickle-cell anemia is due to a mutation at the 6th codon of the β gene (Glu->Val).
Explanation:
i googeld it
Codon in the sickle cell DNA is altered by a single nucleotide substitution that is from GAA to GUA that is in option 2, which is a change from the nucleotide adenine (A) to uracil (U) and this takes place in the beta-globin gene. option 2 is correct answer.
What is the significance of sickle cell anemia?The codon for glutamic acid is GAA is present in normal hemoglobin and changes to GUA in the sickle cell variant due to the A to U substitution at the nucleotide of the codon, and this single nucleotide substitution in the beta-globin gene leads to a change in the amino acid sequence of the protein and a change in the cell structure . This can lead to a variety of health problems, such as anemia and pain and other kidney related diseases.
Hence, a codon in the sickle cell DNA is altered by a single nucleotide substitution that is in option 2 , which is a change from the nucleotide adenine (A) to uracil (U) in the beta-globin gene, so here option 2 is correct answer.

through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
These predators would belong to keystone species. The correct option is B.
Thus, Predators at the highest levels are frequently regarded as keystone species in an ecosystem. Compared to their biomass or abundance, keystone species have a disproportionately strong influence on the composition and operation of their ecosystem.
They are essential in maintaining the ecosystem's balance and preventing the overpopulation of particular species by controlling the populations of other species there.
The dynamics and biodiversity of the ecosystem can be significantly impacted by the removal of a keystone species.
Thus, These predators would belong to keystone species. The correct option is B.

Which is a reason for antimicrobial resistance being higher in a biofilm than in free-floating bacterial cells
Answers
Biofilms are resistant to antimicrobial chemicals due to genetic diversity.
How do biofilms increase antibiotic resistance?Biofilms are considered as a reservoir of genetic diversity. The emergence and spread of antibiotic resistance genes increase in biofilm due to horizontal gene transfer (HGT).
HGT can happen through the transfer of plasmids among microorganism cells in a biofilm through conjugation so that's why the antimicrobial resistance is higher in a biofilm than in free-floating bacterial cells.
