Answer:
b. Ngb-H64Q has a higher affinity than hemoglobin for both carbon monoxide and oxygen. However, Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.
Explanation:
A study of neuroglobin (Ngb), a hemoglobin-like protein present in the brain, was done at the University of Pittsburgh by a team of researchers. Upon testing the red blood cells of a mouse that contained carbon monoxide, they found that Ngb-H64Q was significantly better at removing CO from hemoglobin than 100-percent oxygen treatment. Hence Ngb-H64Q binds to carbon monoxide with a higher affinity than to oxygen.
Answer: The fight or flight response
Answer:
See answer below
Explanation:
Hi there,
Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons first.
Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.
thanks,
Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
Answer:
Promoter is located upstream and terminator is located downstream relative to the transcription start site.
Explanation:
Transcription start site is the site from where the transcription starts which is denoted by +1. The sequence of nucleotides which is present backword to them called upstream sequence and nucleotide sequence which is present in the forward direction of transcription start site are called downstream sequence.
Promoter sequences are present upstream to the transcription start site and are denoted with a minus sign and terminator sequence is present downstream to the transcription start site.
