Answer:
A-Antibodies protect us from getting the exact same virus twice
Explanation:
Answer:
Transcription and RNA processing (splicing)
Explanation:
Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.
This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.
Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.
Selective breeding on food crops may create stronger, and more healthy crops. The idea is to find your best crops, and breed them with other crops sharing the traits you want.
Homeostasis is the property of living organisms in which internal systems are kept in balance. Plants stay cool in the desert heat through their reflective surfaces, reduced leaves, or leaves that are parallel to the sun.
