Oct 4, 2019 · Function of a Chromosome The chromosome holds not only the genetic code, but many of the proteins responsible for helping express it. Its complex form and structure dictate how often genes can be translated into proteins, and which genes are translated.
Aug 15, 2020 · Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique. The term chromosome comes from the Greek ...

A chromosome is a package of DNA with part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes. Google Classroom. DNA, chromosomes, and genomes. Homologous chromosomes, sister chromatids, and haploid/diploid. Introduction. When a cell divides, one of its main jobs is to make sure that each of the two new cells gets a full, perfect copy of genetic material.
- So cells go under mitosis and meiosis. DNA is copied and split, but wouldn't that mean the other org...There is a production of cellular organelles and proteins during the life of the cell prior to replication. And, in fact, some of the cellular orga...
- sperms have 1 sex determining chromosome x or y or it has 2 both x and y?Sperm cells contain either an x chromosome or a y chromosome, not both. They have only one sex determining chromosome, and that can be x or y.
- The general concept of mitosis is one cell splitting into two. But, the text does not discuss how an...In addition to what Aleksandr has said here, you may also wish to consider that mature organs contain many cells which no longer reproduce, but sim...
- how does DNA get to the cells in the body?All cells start from the original fertilized zygote. The two gametes (sperm and ovum) contain 23 chromosomes(n) each and when the sperm fertilizes...
- How many DNA are there in a chromosomes?A chromosome has many genes, a combination of genetic information that gives rise to characteristics, but it is only _one_ extremely super long DNA...
- In the first paragraph (DNA and Genomes), it says that _almost_ all cells in the human body have DNA...Yes - red blood cells are enucleated to make more space for hemoglobin, the protein that binds to oxygen.
- what is the difference between chromatin, chromatid and chromosome ?Chromosomes are the largest out of those 3, with an "X" shape. Chromatids are each half of the Chromosome, if it was cut vertically. Finally, chrom...
- _Cancer cells divide after death but why doesn't a normal calls divided after death?_Communication Cancer cells don’t interact with other cells as normal cells do. Normal cells respond to signals sent from other nearby cells that sa...
- chroma means colored and soma means body. . . It means chromosomes are colored, right?It actually comes from the fact that chromosomes can easy accept/take up dye. Heres a link I found: https://www.vocabulary.com/dictionary/chromosome
- Can you explain me the basic understanding about mitosis and meiosis? I am always getting confused b...Meiosis is for sex cells or gametes (these cells don't have the same genetic makeup as the original germ cell), and mitosis is to copy and reproduc...
Genes are pieces of hereditary material that are passed from parents to offspring. Genes are part of cell structures called chromosomes. In multicellular organisms, chromosomes are found in the nucleus of the cell. Each of these chromosomes contains one, long molecule of DNA, or d eoxyribo n ucleic a cid.
Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division. This ensures that our inner workings proceed smoothly and efficiently.
