Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

Answer:
Wind blows from areas of high pressure toward areas of low pressure.
Explanation:
Wind blows from areas of high pressure toward areas of low pressure.
it doesn't blow in a straight line and winds blow clockwise around an area of high pressure and counter-clockwise around low pressure.
high,low
is the correct choice blood
brine pools, and anaerobic black organic mud. Which of these groups are
the students most likely researching?
Archaebacteria
Eubacteria
Plantae
Protista
Answer:
Its about Archaebacteria.
Explanation:
Archea means ancient. Archaebacteria are unicellular organisms. All the living forms initially were classified into five kingdom classification which includes: Monera (includes all prokaryotes), protista, fungi, plantae and animalia. Later several genetics and molecular biology studies revealed that a class of prokaryotes is different from all other modern bacteria, these were called archaebacteria. They live in extreme environments like volcanic hot springs, extreme salty or very acidic surroundings.
