The isolation barriers prevents two of the species to mate, resulting in them evolving into different species
Answer: The answer is C. The arthropods are more easily caught and eaten during the process.
Explanation: If you search the answer you’ll get: Approximately 85% of arthropod deaths occur during molting. The insect is extremely vulnerable to predators during and right after the shedding of its old skin.
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
Answer:
D. Nucleic acids attach to the bases in the DNA.
Explanation:
Transcription begins when an enzyme called RNA polymerase is added to the DNA template and begins a new chain a new chain to produce complementary RNA.
During the RNA synthesis transcription takes place, then the cap and tail is added and then splicing occurs.
RNA polymerase moves from the 3' end to the template strand creating the RNA-DNA double helix or similar the base sequences. This makes a chain with each sugar by the set of bonds called phosphodiaster linkage. Then, the enzyme unwind the DNA and begins the synthesis of RNA.
Therefore, D. Nucleic acids attach to the bases in the DNA.
