The enzyme that makes RNA knows where to start transcribing the DNA by knowing where to start transcribing at the promoter site. For example,<span> TATA Box in Eukaryotes. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
There are approximately 4.7 to 5.5 liters and 1.2 to 1.5 gallons of blood in a human's body.
Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
Mitochondrial DNA can be traced for generations. It is because of the fact that unlike nuclear DNA, mitochondrial DNA rarely gets mutated. The frequency of mutations in the mitochondrial DNA is approximately one every 3,500 years per nucleotide. That is why mitochondrial DNA of a person is almost similar to his/her direct maternal ancestor. So, it can be used to match lineages amongst people.
