Answer:
3'-GCTATAACTCGATTCGAA-5'
Explanation:
The DNA is a macromolecule formed by two strands of polynucleotides forming a double helix.
These chains are composed of monomers called nucleotides, there are 4 different types in DNA, called nitrogenous bases: two purines, guanine (G) and adenine (A) and two pyrimidines, thymine (T) and cytosine (C). They are joined by covalent bonds in each chain.
These bases are complementary: G with C, and A with T between the two strands by hydrogen bonds making the double-stranded DNA molecule.
A sequence 5'-CGAT-3' is equivalent to a sequence written 3'-ATCG-5' , because the 5' and 3' notation defines the direction of reading. If one strand is noted 5' to 3', then the complementary strand will be from 3' to 5' in the same sense.
So, all we need to do is write the complementary bases from the 3' end to 5':
5'-CGATATTGAGCTAAGCTT-3'
3'-GCTATAACTCGATTCGAA-5' (answer)
D. Things that are kept constant.
Controls are used in an experiment where some variable is being changed. By only changing one thing and keeping the others constant they can make sure that any change in the results is caused by the variable and not the constant, since the constant didn’t change.
Answer:
La interacción biológica entre uno y otro consiste en que el predador o depredador da cacería a la presa y se nutre de la materia orgánica de su cuerpo, obteniendo así la energía y la materia necesarias para subsistir.

Answer:
Las células procariotas están rodeadas por una membrana plasmática y al igual que las células eucariotas tienen ADN, citoplasma y ribosomas. También tienen paredes celulares y pueden poseer una cápsula celular. Los procariontes tienen un solo cromosoma de gran tamaño, que no está rodeado por una membrana nuclear.30-Jan-2013
