1. Option C is correct. RNA nitrogenous bases sometimes bond with other bases.

2. Option D is correct. Genetic code is the 3 letter code of ordered nitrogenous bases.

The RNA form bonds with another strand also found in the human cell.

It's true that RNA is usually single-stranded and DNA is double-stranded.DNA forms a helical structure while RNA does not.

So Option A and B can be eliminated.

The genetic code:

It is the 3 letter code of ordered nitrogenous bases that are found in the RNA. This code for amino acids.

So we can conclude that the Genetic code is the 3 letter code of ordered nitrogenous bases.

Answer from: f1refoxx

RNA and DNA are the nucleotides found in the cell. These nucleotides code the genetic information and play a crucial role in the central dogma of molecular biology.

The Correct answers are:

Option C: The nitrogenous bases of RNA are never hydrogen-bonded to other basesOption D: The order of nitrogenous bases

DNA is a double-stranded helical structure that consists of genetic information. The nitrogenous base, a pentose sugar, and phosphate backbone make up the DNA molecule.

On the other hand, RNA is a single-stranded molecule, that consists of a nitrogenous base, a pentose sugar, and a phosphate group. The nitrogenous base pairs in the DNA and RNA are similar, such that purines and pyrimidines form hydrogen bonds that are complementary to each other.

The genetic code is the three-letter code, which forms the ordered nitrogenous base pairing in the DNA and RNA. The genetic codes are made up of amino acids.

These codons are transcribed and translated to convey the information present in DNA and RNA.

Therefore, DNA and RNA have nitrogenous bases bonded by hydrogen bonds and the order of nitrogenous bases is complementary in these nucleotides.

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa.which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
