Marshall Nirenberg and Heinrich Mattaeis contributed to out current understanding of the genetic code by discovering genetic codons. Their experiment deciphered the first of the 64 triplet codons in the genetic code by using nucleic acid homopolymer to translate specific amino acids. Their experiment cracked the first codon of the genetic code and showed that RNA controlled the production of certain types of proteins.<span />
True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
4 cells would be created after meiosis and each cell would have 7 chromosomes.
<h3>Meiosis</h3>
Meiosis is the division of non-vegetative cells. It is a reductional division during which the ploidy level of the parent cell is halved in the daughter cells.
Thus, a cell with 2n = 14 that undergoes meiosis will produce daughter cells with n = 7.
Usually, 4 daughter cells are produced at the end of meiosis.

Answer:
The main natural carbon sinks are plants, the ocean and soil. Plants grab carbon dioxide from the atmosphere to use in photosynthesis; some of this carbon is transferred to soil as plants die and decompose. The oceans are a major carbon storage system for carbon dioxide.
