Is there any difference between DNA profiling and DNA sequencing?
And are co dominance and incomplete dominance the same thing?
DNA profiling is a means of comparing individuals and determining whether or not they are related. It usually uses Short Tandem Repeats (STRs) which are repeated sequences of hypervariable, non-coding DNA. However, DNA sequencing is used to determine the exact order of bases of DNA. So this could be like using probes to determine the specific base sequence of target DNA.
Co dominance occurs when two different alleles are equally dominant and thus equally and independently expressed in the phenotype, whereas incomplete dominance results in an intermediate form of the two alleles.
However, we need not know about incomplete dominance.
Aerobic respiration results in the production of ATP. In aerobic respiration, pyruvate:
a) passes through the outer membrane of the mitochondria
b) is a product of the ETC reactions
c) is a reactant of the glycolysis reactions
d) enters the Krebs cycle unchanged
Sorry for the noob question... forgetting the basics
A) as pyruvate is a product of glycolysis, which occurs in the cytosol, and is a reactant of the Krebs cycle, which occurs in the mitochondrial matrix. It is first converted into Acetyl co-A before entering the Krebs cycle.
