2.7.- COMPARACION ENTRE LAS CELULAS Recuerda que las celulas procarionticas son celulas primitovas que no tienen organelos rodeados por membranas. Su material nuclear se encuentra flotando en el citoplasma. Las bacterias se clasifican como procariontas. Las celulas eucariontas son las mas avanzadas y contienen organelos rodeados por membranas. Su material nuclear esta rodeado por una membrane nuclear. Las celulas de las plantas‚ los hongos y los animals son eucarionticas. Las celulas de las plantas

Shakespeare’s Sonnet 102 Poet and screenwriter‚ Susan Griffin‚ once said‚ “A story is told as much by silence as by speech.” This statement underlines the fact that just because words are not spoken‚ it does not mean that there is no meaning behind the silence. Someone’s lack of words can have as much‚ if not even more‚ power as another’s most persuasive speech. In Sonnet 102‚ Shakespeare explains why he believes in the power of silence regarding his feelings towards his true love. His allusion

1. Do you believe it is still possible that new musical instruments could be invented and widely distributed? Empirically‚ though the diversity of musical instruments has reached a quite high level‚ human has never stopped their exploration into music. So‚ I think it’s highly possible that several new musical instruments can be invented and widely distributed. The musical history has already proved this. Before 19th century‚ the majority of musical instruments are acoustic‚ and most people at

particular places on the chromosomes called loci. During meiosis‚ each pair of alleles splits up or segregates so that only one allele from each pair is contained within a gamete (egg or sperm.) This is Mendel’s Law of Segregation. In sexual reproduction egg and sperm from parents unite to form a new individual or zygote. Thus‚ each parent contributes one allele for each genetic locus. Mendel’s Law of Independent Assortment states that during meiosis‚ each pair of alleles is assorted randomly and inherited

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

Before the chromosomes condense the nuclear membrane goes through meiosis which is cell division between and egg and sperm cell that determines the sex of a baby. The sex is found by the sperm which carries a X and Y sex chromosomes. Before the cell divides two sets of chromosomes pair together and swap segments. The second
