This is because daughter cells are identical to the original cell.
Although during the process of mitosis the number of chromosomes changes, the final number of chromosomes in each daughter cell is always the same number as were in the original cell.
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 number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
Answer:
The cell membrane is an important factor for homeostasis to happen.
Explanation:
Because the cell membrane is a lipid bilayer that prevents that passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
