What proteins are associated with eukaryotic chromosomes? Give the function of the chromatin. (a) What is the composition of a DNA fragment? (b) What is a DNA fragment made of? 1. What is the composition of a DNA fragment? 2. What is a DNA fragment made of?
What is DNA composed of? Which genetic material came first in the world, RNA or DNA? Which came first, DNA or RNA? DNA and RNA are both made of parts called. What is a complex of DNA and proteins that constitutes eukaryotic chromosomes called? Which bases are found in...
Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have acapsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface. What are the two typ...
Chromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, chromosomes form the nucleoid that is ...

are made up of chromatin. Chromatin made up of the threads of DNA forms the structure of chromosomes. The DNA gets condensed to form chromosomes. Genes are the segments of DNA. The code for proteins. This means chromosomes are made up of DNA which contains many genes in...
A newly made eukaryotic cell begins a life cycle that includes the following phases: G1(first gap phase), S (synthetic phase), G2(second gap phase) and mitosis. In G1, the cell makes duplicates of every component of the cell with the exception of the chromosomes. In S, which takes ...
Deoxyribonucleic acid (DNA)is the blueprint for life. Inside the nucleus of a microscopic eukaryotic cell, chromosomal DNA stores all the instructions needed for making a full-fledged adult organism. Nuclear DNA is organized intochromosomes; humans have 46 total per cell.Haploidvs.diploidrefers to...

This method of vaccination traces its routes to 1989, when scientists at the Salk Institute in California were the first to report the successful transfection of mRNA into a range of eukaryotic cells (cells that make up multicellular organisms). Throughout the rest of the early 1990s, variousin...
