A mutant bacterial cell has a defective aminoacyl synthetase that attaches a lysine to tRNAs with the anticodon AAA instead of t

he normal phenylalanine. The consequence of this for the cell will be that:_____________a) none of the proteins in the cell will contain phenylalanine.b) proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.c) the cell will compensate for the defect by attaching phenylalanine to tRNAs with lysine-specifying anticodons.d) the ribosome will skip a codon every time a UUU is encountered.e) none of the options will occur; the cell will recognize the error and destroy the tRNA.

Answer:

Proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.

Explanation:

Mutation may be defined as the sudden or heritable change in the genetic sequence of the organisms. The mutation can change the phenotype and genotype of the organisms.

The AAA codes for the lysine. The mutation attaches the anticodon AAA instead of normal phenylalanine. The aminonacids AAA will code for the lysine and no phenylalanine is observed in the cell as phenylalanine is coded by UUU and not by AAA.

Thus, the correct answer is option (b).

What pattern of growth will a population with limited resources show?
Paladinen [302]

Answer:

b. logistic

Explanation:

Logistic growth occurs when growth begins as exponential but then slows and flattens out (or becomes constant) at a certain point. The growth of a population is logistic because at the beginning all populations growths are exponential. This is because there are more than enough resources when a population is small. However, once a population reaches carrying capacity, which is the limit an environment can hold, resources begin to run out and the growth becomes slower and constant. Logistic growth is also known as an "S curve" because on a graph the growth resmbles an S.

the grouping that includes turtles, lizards and snakes, crocodiles and alligators, birds, and bats is: polyphyletic. monophyleti
nevsk [136]

The grouping that includes turtles, lizards and snakes, crocodiles and alligators, birds, and bats is monophyletic.

Monophyletic taxon : A team composed of a collection of organisms, together with the most current frequent ancestor of all these organisms and all the descendants of that most latest common ancestor. A monophyletic taxon is also called a clade.

​if the carbohydrate content of the diet is insufficient to meet the body's needs for glucose, what can be converted to glucose?
BigorU [14]
The answer is "amino acids<span>".
 
Carbohydrates are easy to breakdown to make energy. But, if there is a carbohydrate deficiency, then the body will start to breakdown amino acids to make energy. The main energy sources are carbohydrates, fats and proteins. In order to keep the body alive, body will breakdown nucleic acids (RNA, DNA) when there is not enough food to make energy.</span>

Can plants or animals in an ecosystem use energy after it leaves its ecosystem
Tom [10]

The word ecosystem refers to the all of the living species as well as non-living elements in a particular environmental area. For instance, a lake, swamp, coral reef, forest, or a prairie would each be considered an ecosystem. Ecosystems can vary greatly in size and individual characteristics -- for instance, the ecosystem of a puddle differs greatly from that of a swath of tundra.

Despite these disparities, all ecosystems function similarly in the way in which energy flows into, through, and out of them through the energy cycle.
