If the address book of your old phone is relatively small and you only want to copy the phone numbers to your new cell phone, simply use the SIM card.ransfer Contacts via your Computer.

Introduction to Chromosomes. Chromosomes are made up of a strand of DNA tightly wrapped around proteins called histones. This makes the DNA compact and able to fit inside the cellâs nucleus.A gene is a segment of DNA that encodes for a trait. Therefore, genes are located on chromosomes.ntroduction to Chromosomes. Chromosomes are made up of a strand of DNA tightly wrapped around proteins called histones. This makes the DNA compact and able to fit inside the cellâs nucleus.
Today, researchers know that nucleosomes are structured as follows: Two each of the histones H2A, H2B, H3, and H4 come together to form a histone octamer, which binds and wraps approximately 1.7 turns of DNA, or about 146 base pairs.igure 1: Chromosomes are composed of DNA tightly-wound around histones. Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes.
