Gene mutations can be positive, negative, or neutral. Suppose that the normal gene in Model 2 produced a polypeptide that was necessary for cellular respiration.
A) Choose a mutation from those in Model 2 that might be positive for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
Genes encoded in our DNA result in the production of proteins that perform specific functions within human's cells and various environmental factors and spontaneous events can lead to changes in genes, these changes are called mutations, can lead to alterations in the structure and activity of the proteins in the cells use. Mutations are the source of all new alleles in nature and arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Therefore,a gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis) within a single coding section of DNA. Variations in alleles lead to variations in organisms within a population, cellular respiration, i.e. the reduction of inspired oxygen to water, which powers cell function, also generates highly reactive oxygen species that can damage DNA, with the purine bases G and A being particularly susceptible to this kind of attack,so Positive mutations lead to the organism having a better chance of survival, which means the mutation may be passed on to the offspring.
B) Choose a mutation from those in Model 2 that might be negative for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.
Due to one's metabolism, the human body replaces every cell within the cellular respiration process and any mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However, these changes are considered to be negative mutations, because they are not permanent changes to the cell, however such mutations may lead to an early death probably before the organism can produce offspring.
Answer: Option A
Explanation:
The correct statement is that the there is a difference in protein which is found in the outer membrane and inner membrane of the mitochondria.
The inner membrane of the mitochondria is folded to allow maximum surface area for the energy production.
The inner part of the mitochondria contains the enzyme ATPase for energy production.
The outer membrane of the mitochondria contains enzymes for the export and import of the various materials with the help of TOM40 complex and TIM23 complex.
The answer for this is legumes.
Answer:
The complementary base pair is ATG TTT GTG ATA TGG CGC ATT TAC TAA
Explanation:
As per the complementary base pairing rule of DNA
C pairs with G and vice versa
A pairs with T (in DNA) or U (in RNA)
Breaking the given strand into triplets, we get -
TAC AAA CAC TAT ACC GCG TAA ATG ATT
ATG TTT GTG ATA TGG CGC ATT TAC TAA
Answer:
Ur answer is D. They should grow native plants on the lodging property to attract local wildlife.
Explanation:
Hope this helps :). Have a great day!
