Cloning will not lead to designer babies because clones are a complete copy of the person being cloned. The clone would need to be genetically modified to be considered designer
Answer:The number of daughter atoms increase and the number of radioactive (parent) atoms decrease.
Explanation:
In the process of radioactive decay the unstable atom nuclei of the parent nucelus breaks down and split so as to release the daughter atoms or nuclei along with release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of daughter atom increases.
D. 90%
Cells prepare for mitosis in Interphase and spend most of their lives in this phase. It is also called the "daily living" state of the 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.
the relationship between abotic and biotic environment is called ecosystem.
