So I went to it and found a lot of people doing it soooo I went it saw 222 +-5 and cancer treatments are
Answer:
a. eukaryotes have three different RNA polymerases, whereas prokaryotes only have one RNA polymerase
Explanation:
The initiation represents the beginning of RNA production. Initially, RNA polymerase (transcription catalyzing enzyme) recognizes in DNA the so-called promoter regions. In prokaryotes, there is only one type of RNA polymerase; In eukaryotes, three RNA polymerases are described, and thus the transcription process in this group is more complex.
In the initiation step, we also observe the opening of the DNA strand, a process known as unfolding. This opening occurs because of the rupture between the connections that arise between the bases.
They provide evidence of genes coding for structures that are present not because they are useful, but because they were once useful to an ancestor.
<span>One example is the plantaris muscle. This is a long, thin muscle in the human foot and calf that serves no significanl purpose in humans ... in fact, it is regularly removed by doctors harvesting muscle tissue to use in reconstructive heart surgery, because its removal leaves no loss of function in walking or balance. </span>
<span>However this same muscle is found more fully developed in the feet and calves of other primates. It is the muscle used for grasping with the feet.</span>
Answer: Almost certainly have no effect.
Explanation:
Most mutations that happen to your dna will barely ever show themselves in any way. And they probably won't even be passed to your children, because only mutations that happen in your gametes will get passed.
