Wild‑type E. coli cells can synthesize all 20 common amino acids, but some mutants, called amino acid auxotrophs, are unable to

synthesize a specific amino acid and require its addition to the culture medium for optimal growth. Besides their role in protein synthesis, some amino acids are precursors for other nitrogenous cell products, such as the purine and pyrimidine nucleotides. Consider the three amino acid auxotrophs that are unable to synthesize glycine, glutamine, and aspartate, respectively. For each mutant, identify the nucleotide product or products which the cell would fail to synthesize by placing the nucleotide in the bin next to the auxotroph.

Answer:

Complete questions include: Answer Bank: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides.

Explanation:

Glycine Auxotroph: Guanine nucleotides and adenine nucleotides (Purine nucleotides)

Glutamine auxotroph: Guanine nucleotides and adenine nucleotides (purine nucleotides)

Aspartate auxotroph: Guanine nucleotides, uridine nucleotides, adenine nucleotides, cytosine nucleotides Both purine and pyrimidine nucleotides)

The amino acids glutamine, glycine, and aspartate provide all the nitrogen atoms of purines in a two ring-closure steps to form the purine nucleus. Pyrimidines are synthesized from carbamoyl phosphate and aspartate.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chrom
Damm [24]

Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

  • G1 (gap 1 phase)-the cell grows and becomes larger
  • S phase- replication of DNA, duplication of centrosomes
  • G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

  • prophase-condensation of chromatin into chromosomes,  the nuclear envelope breaks down, mitotic spindle formation
  • metaphase-the chromosmes line up (metaphase plate)
  • anaphase-the siste chromatides move toward opposite cell poles
  • telophase-the nuclear envelope forms again, cell division is almost complete

Why are some of carl linnaeus’s classifications of organisms incorrect?
madreJ [45]

Answer:

Some of Carl Linnaeus classifications of organisms are incorrect because he classified them base on their appearances and actions

Explanation:

Carolus Linnaeus is the father of taxonomy, which is a system of naming and classifying organisms. He classifies organisms base on their appearances and actions instead of their relationships. He invented a system of classification called hierarchical system of classifications. This system include 8 taxa, dormain, kingdom, phylum, class, order, family,genus and species.

Carine went to the doctor for a physical. Her blood pressure was 80/50. What describes Carine’s condition, and what is the most
Korolek [52]

Hello!! Since there is no mention of weight in the question, I would assume that she is pregnant. Whenever someone's blood pressure is low, it is referred to hypotension. Whenever someone's blood pressure is high, it is referred to hypertension. I would say your best answer is A - She has hypotension because she is pregnant. I hope that is the right answer you are looking for. Have a great day!! :)
