Imagine you discover a yeast mutant that exhibits a general inability to grow and thrive compared to wild-type yeast. You predic

t that the mutant has a defect in a basic process necessary for survival and therefore examine the cellular levels of 50 common proteins, as well as the levels of tRNAs and rRNAs. You discover that tRNA and rRNA levels are normal, but the levels of all of the proteins you examine are much lower than they are in the wild-type yeast.
a) This suggests that there is a general defect in ____________.
O Transcription
O DNA Replication
O Polyadenylation
O All of the above

Answer:

The answer is all of th above.

Explanation:

Proteins are produced through mRNA which is coded from the DNA copy, and then taken to the ribosomes which produces the actual protein. Whether there is a mistake in the coding of the process does not affect the tRNA or rRNA levels. For the protein levels to be much lower, there needs to be a defect in DNA replication, which leads to the defects of transcription and polyadenylation. So the answer is all of the above.

I hope this answer helps.

if the effective rate of reproduction of an asexual lineage is 12 per year, what would be the effective rate of reproduction of
allsm [11]

The effective rate of reproduction of an asexual lineage is 12 per year, what would be the effective rate of reproduction of a lineage are 3.

Although the primary replica quantity, R zero, is beneficial for information the transmissibility of a ailment and designing diverse intervention strategies, the conventional threshold amount theoretically assumes that the epidemic first takes place in a totally inclined population, and hence, R zero is basically a mathematically described amount. In many instances, it's miles of realistic significance to assess time-structured versions withinside the transmission capability of infectious diseases.

R(t) indicates time-structured version because of the decline in inclined individuals (intrinsic factors) and the implementation of manipulate measures (extrinsic factors). If R(t)<1, it indicates that the epidemic is in decline and can be seemed as being beneathneath manipulate at time t (vice versa, if R(t)>1). T

Cellular respiration is the process that converts nutrients into ATP (adenosine triphosphate), a storage molecule that provides
Genrish500 [490]

Answer:

Plants perform photosynthesis and cellular respiration.

Explanation:

  • Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
  • Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
  • Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
  • Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.

If you wanted to see a cell wall, where could you look?.
tatyana61 [14]

Answer:

A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.

Explanation:

A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
