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.

carbondioxide last in about 300 to a 1000 years in the atmosphere
<span>A seatbelt should be fastened so as to run diagonally across the chest and to fit low and tight across the waist. This ensures that, during the rapid deceleration experienced during a crash, the seatbelt will perform the intended function, that is, to keep the passenger in place within the vehicle.</span>
The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.
We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.
