Consumers must obtain their nutrients and energy by eating other organisms. Decomposers break down animal remains and wastes to get energy.
A DNA sequence that is 15 nucleotides long would normally give rise to a polypeptide sequence that would be 5 amino acids long. This is assuming that all the nucleotides in the DNA sequences are strictly coded to form only sense codons and not a single nonsense codon, also called termination codon
A sense codon is a set of three nucleotides also called a triplet, that codes for a particular amino acid. A DNA sequence of 15 nucleotides has 5 codons.
A nonsense or termination codon is one that does not code for any amino acid. There are three nonsense codons found on mRNA, and these are UAA, UAG and UGA. So if the DNA sequence has one of these, then the amino acids in the polypeptide chain will be 4 in number
We could explain the consequences of not recycling, composting, and conserving in different campains. We could also make it a requirement to learn in science class so children become aware of it and change it for the better later on.
Answer:
Mutation plays an important role in evolution. The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Answer:
The term gene expression means the process by which the information encoded in our DNA is used to synthesize a functional product, such as a protein molecule or other cell structures.
