Hint:Chromosomes 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 contain...
Chromatids are produced fromchromatinfibers during both meiosis and mitosis. Chromatin is composed ofDNAand skeletalproteinsand is called a nucleosome when wrapped around these proteins in sequence. Even more tightly wound nucleosomes are called chromatin fibers. Chromatin condenses DNA enough to fit w...
called chromatin. Chromatin consists of DNA and proteins that serve to compress and relax the overall structure of chromosomes depending on the cell's state of division. Most of these proteins are calledhistones, which are octamers of eight subunits, each of which is paired with another...
Why is chromatin packaged after DNA replication? a-What is the purpose of the mRNA transcript? b-Explain why the term ''transcription'' is used to describe this part of the process cells use to make proteins. 1- What is the purpose of the mRNA transcript? ...

During this process, atoms are rearranged but nothing new is made and nothing is destroyed. The reactants in a chemical reaction are the substances that are used in the reaction and are turned into something else. Reactants show up on the left side of the equation before the arrow. The...
What component of DNA is referred to by a 5' carbon? What is the primary level of DNA structure? What has nucleic acids? Which organic molecules are nucleic acids? What are the basic building blocks of DNA and RNA? What is the basic unit of DNA packaging in chromatin?
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
acrosome. The DNA of the spermatid turns highly condensed, experiencing packaging. Packaging of DNA with particular nuclear basic proteins is the first step that is later substituted during the elongation of spermatids by the protamines. The packed chromatin hence produced is inactive transcriptionally...
How is DNA structure similar to a protein? What is the primary function of DNA? What makes one DNA molecule different from another? What is the basic unit of DNA packaging in chromatin? How does water affect DNA structure? How is the information within our DNA structured?
