What is a chromosome composed of quizlet?
Chromosomes are made up of DNA and support proteins.
What are the two main parts that make up a chromosome?
Chromosomes mainly constitute DNA and histone proteins. DNA is wrapped around a core of histone octamer to form a nucleosome. Nucleosomes are the repeating unit present in the chromatin.
What is a chromosome and what does it contain?
Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the building block of the human body. Chromosomes also contain proteins that help DNA exist in the proper form.
Are chromosomes composed of DNA and histones?
Figure 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.
What are chromosomes made of quizlet mastering biology?
Chromosomes are made up of protein and nucleic acid. Chromosomes are found in the nucleus. Genes are made of DNA. Genes are located on chromosomes.
What are chromosomes made up of Brainly?
Each chromosome is made up of protein and a single molecule of DNA (deoxyribonucleic acid). RNA is synthesized in nucleus but found mainly in the cytoplasm of the cell. Hence, chromosomes are not made of RNA. Therefore, chromosomes are made of DNA and protein.
What are the main parts of a chromosome?
A chromosome has generally 8 parts; Centromere or primary constriction or kinetochore, chromatids, chromatin, secondary constriction, telomere, chromomere, chromonema, and matrix.
Which are the two main parts that make up a chromosome a DNA and protein B DNA and RNA C RNA and phosphate D sugar and phosphate?
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.
