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.
Answer:
The Clean Water Act (CWA) can be considered as one of the effective program which impacted the water quality in the United States. Under this Act, quality standards for surface water were generated.
This Act has set wastewater standards for the industries and it ensures that industries do not pollute the clean water. The Clean Water Act (ACT) made it unlawful to discharge any pollutant in waters and set a fixed amount for it. Beyond that amount, polluting water is considered to be illegal.
The correct option is C.
if two organisms are in the same class then they will be in the same phylum. The biological classification hierarchy is arranged in such a way that, two organisms who belong to a lower division on the hierarchy will automatically be in the same group in the higher division.
The arrangement from the smallest to largest hierarchy is this: specie, genus, family, order, class, phylum and kingdom.
The density of the clay plate is 1970 kg m⁻³
the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams
so,V= 30 cm⁻³=3x 10-5 m and M= 59.1grams= 0.0591 kg
Therefore, the density of the plate is: M/V
=>d = 1970 kg m⁻³
