Answer:
RNA and DNA wouldn't be read in the proper order and would code for different proteins, with devastating consequences.
Explanation:
Directionality is important in DNA and RNA because it ensures that all transcription and translation occurs in an organized and uniform manner. Without directionality, the DNA and RNA machinery would get confused and read the nucleotides into the machinery backward, which would give the sequence an entirely different meaning.

de que sustancia esta lleno el cromosoma
Answer:
Los cromosomas están compuestos por dos cadenas largas de polinucleótidos asociados a proteínas histonas
Explanation:
Un cromosoma es una molécula lineal de ácido desoxirribonucleico (ADN) la cual está compuesta por dos cadenas de nucleótidos dispuestas en forma de doble-hélice. En el ADN, cada nucleótido está formado por una azúcar desoxirribosa, un grupo fosfato y un tipo de base nitrogenada (los cuatro tipos de bases nitrogenadas que forma nucleótidos en la molécula de ADN son Timina, Guanina, Citocina y Adenina). La molécula larga de ADN en doble hélice se encuentra asociada a proteínas histonas para formar las fibras de cromatina. Aproximadamente 150 pares de bases de la molécula del ADN se encuentran enrolladas con las histonas H2A, H2B, H3 y H4 (dos subunidades de cada una) para formar un nucleosoma, la unidad básica de la cromatina. Finalmente, es importante indicar que la molécula de ADN contiene regiones no codificantes y regiones codificantes, es decir, fragmentos de ADN los cuales son utilizados como templados para producir moléculas de ARN mediante un mecanismo conocido como transcripción. Los ARN mensajeros (ARNm) son un tipo especial de ARN sintetizados a partir de fragmentos codificantes de ADN conocidos como 'genes'. Posteriormente al proceso de transcripción, estos ARN mensajeros sirven a su vez como templados para la síntesis de proteínas en los ribosomas, mediante un mecanismo conocido como 'traducción'.

Based on what you know about the relationship between the burning of fossil fuels (coal, oil, gasoline) and CO2, how could this also contribute to the cyclic nature of CO2 concentrations throughout the year?
Explanation:
levels of the carbon dioxide in the atmosphere rise and fall each year as plants through photosynthesis and respiration take up the gad in the spring and summer and release it in fall and winter. Now the range of that cycle is expanding as mire carbon dioxide is emitted from burning fossil fuels and other human activities

A. asexually buy the process of MEIOSIS
B. sexually by the process of MITOSIS
C. sexually by the process of MEIOSIS
D. asexually by the process of MITOSIS
Answer:
D
Explanation:
Asexual reproduction (requiring one parent) forms exact copies of the parent cell. The type of cell division that produces exact copies is mitosis. Therefore the answer is D.
Answer:
D. asexually by the process of Mitosis
Explanation:
Amoebas make exact copies of themselves. Therefore, they reproduce asexually by the process of Mitosis.
What is the name of one convection cell that forms because of the Coriolis effect? How does the air move in that convection cell?
Answer:
Hadley CellsWarming air causes it to ascend. The cool air will sink. The action eventually results in a convection cell, with air rising, traveling to the side, dropping, and returning. This heat-driven air movement circulates heat throughout the atmosphere.OAmalOHopeO

prairie dogs north america Indirect relationship (between keystone species and other organisms): Preservation Status:
Answer:
Indirect relationship.
Explanation:
There is indirect relationship between keystone species and other organisms because both species affect each other not directly but indirectly. The keystone predation was the most common of the indirect effects on other abundance of other species. The predation of keystone species decrease the population of keystone species which indirectly increases the population of competitors in that environment.

what scientific term is used to describe all the genes of one organism?
Answer:
The scientific term used to describe all of the genes in an organsim is the genome.
Genome term is used to describe all the genes of one organism, it forms the genotype of an organism.
What is a genome?the entirety of an organism's genetic makeup, or DNA. Nearly every cell in a person's body has a complete copy of its genome. Everything a person needs to grow and develop is encoded in their genome.
Each and every one of the body's cells, such as the skin cell or the liver cell, carries the following set of instructions: DNA makes up the instructions in our genome.
The genome's main job is to preserve, express, and store the genetic material that gives rise to a cell's structural and functional machinery. The genome is a significant part of the cell's structural makeup, nevertheless. Hence, the Genome term is used to describe all the genes of one organism.
