my assignment is to draw a restriction map of the fragment and show distances, in base pairs, between HindIII, SmaI, and EcoRI.
A 1000bp EcoRI restriction fragment (linear) contains a gene you are interested in. first, construct a restriction map of the fragment using the enzymes SmaI & HindIII.
HindIII cut at 700bp & 300bp; SmaI cut at 800 & 200.

Okay, so I'm taking Biology this year, and one of the students asked the teacher how we developed a conscience. My teacher said something like our brains evolved over time or something, and then she changed the subject. It didn't sound very convincing.

I honestly don't understand how people could have developed good and bad all by themselves. Like killing a man is wrong type of thing. Like how did humans develop justice? How do we know what is right and what is wrong? And why do some people have different rights that are wrong to others? And how do we know Hitler wasn't right and we're wrong? Since we're ever changing animals wouldn't we have just maintained what the other animals considered good or bad? Could you please explain how it happened?

I simply ask because I want to be able to defend what I believe.
Thanks much.

Does the recent discovery of blood cells and tissue on the bone of a t-rex by scientist from the hall creek institute at montana proove to everyone that the t-rex isn't millions of years old

i mean yes it could be very old

but come on, blood cells and tissue on a bone thats over 70 million years old,

i think this just gies to show even when the evidence is staring at people in the face, they still want to hold onto a theory that the evdience does not support

i mean if you found blood cells and tissue onb a dinosaur bone, the most logical thing to conclude is that its not even up to a million years old

blood cells last that long do they?

we are all educated people, we all studied evolution, and this um somewhat contradicts it

Your thoguhts please:

If natural selection, mutations, polyploidy, and gene replication/duplication do not add new functional genetic information to DNA (they only delete, scramble, and copy existing information), then how exactly do you account for the astronomical increases in information required to arrive at human DNA with over 3 billion base pairs? And when I say that they copy information, this is subsequent to photocopying a page out of a book; no new information is added. Also, assuming you present a mechanism (which we do not currently observe), how would evolution accomplish this even within 3 billion years, unless it added at LEAST 1 necessary, coherent, and functional piece of information to this DNA every year? Finally, this does not even account for the proteins necessary to carry out instructions for the genome, the role that they play in eukaryote cells, the process of meiosis necessary for sexual reproduction, or the replication of 100 trillion cells necessary to produce a human.

I have this project and I cant find any websites that tell me how I can make an animal cell in 3D. Im really looking for a project that uses simple stuff like everyday things. if possible does anyone know a way that I can make it with styrofoam?

Why are there still monkeys if we evolved from them? Surely they would no longer exist.
