Why would cells die if they were unable to make (or otherwise obtain) the amino acid arginine?

Answers

Answer 1
Answer:

Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.

Explanation:

Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.

Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.

Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning. So the cell dies because it cannot function properly.

Answers

Answer:

UUU

Explanation:

A codon is a sequence of three nucleotide bases in a mRNA molecule that specifies an amino acid. During the process of translation, the mRNA strand is read in a group of three nucleotides at a time. A type of RNA called transfer RNA (tRNA) posseses in its structure another group of triplet nucleotides called ANTICODON, which is complementary to the sequence of bases in the mRNA codon.

The tRNA anticodon recognizes and binds to the particular mRNA codon it is complementary to in order to carry the amino acid it specifies to the growing polypeptide chain In this case, the mRNA codon reads AAA. This means that the anticodon on the tRNA that will bind to this codon is UUU.

Answers

Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.

Multicellular organisms use cell division, mitosis, for growth and the maintenance and repair of cells and tissues. There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. Single-celled organisms may use cell division as their method of reproduction. Regardless of the reason for mitosis, the process ensures genetic continuity. Consider the model of the cell cycle. Which detail(s) from the model best support the argument that cell division promotes genetic continuity?

Answers

Final answer:

The model of the cell cycle provides details about how cell division promotes genetic continuity, including DNA duplication, accurate segregation of chromosomes, and cytokinesis.

Explanation:

The model of the cell cycle provides several details that support the argument that cell division promotes genetic continuity:

  1. During interphase, the cell grows and the nuclear DNA is duplicated. This ensures that each daughter cell receives an exact copy of the genetic material, maintaining genetic continuity.
  2. In the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. This process ensures that the genetic information is accurately passed on to the next generation of cells.
  3. Following mitosis, the cytoplasm is divided through cytokinesis, resulting in two genetically identical daughter cells. This further ensures that each cell receives a complete set of genetic information.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?a. They absorb carbohydrates through the soil.
b. They absorb dissolved carbohydrates via water.
c. They make carbohydrates through the process of photosynthesis.
d. They make carbohydrates through the process of cellular respiration.

Answers

I believe the correct response would be C. Plants acquire carbohydrates by producing them through the process of photosynthesis. This allows plants to then use the formed carbohydrates to build structural polymers, such as cellulose.
