Answer:
Nonspecific immunity is designed to deal only with microbes that are not a threat to the body, whereas, the specific immune system only deals with microorganisms that cause infection.
They became adapted to their new environment and became new species which then were not able to produce fertile offspring.
Answer:
The correct answer is - Genotype : 100 heterozygous (TtRr) and
Phenotype: 100% tall pink.
Explanation:
A cross between dwarf red snapdragon (ttRR) and homozygous tall white plant (TTrr) will form gametes tR and Tr. These gametes fuse and form Heterozygous condition for both traits that is TtRr.
TtRr snapdragons will form tall and pink phenotypically as we know T (tall) is dominant over t (dwarf) and heterozygous condition will be tall. But in condition of color Heterozygous form pink flower.
Thus, the genotype of offspring will be TtRr and phenotype will be all tall and pink for better understanding check punnet square.
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.
