What is the relationship between DNA chromosomes genes alleles and proteins?
What is the relationship between DNA chromosomes genes alleles and proteins?
DNA tells a cell how to make proteins. DNA is arranged on chromosomes in segments called genes. One gene tells the cell how to make one protein. Different variations of a gene are called alleles.
What is the relationship among DNA a gene and a chromosome Mcq?
D) A gene is composed of DNA, but there is no relationship to a chromosome.
Does each chromosome contain both DNA and proteins?
Each chromatid contains a single molecule of double-stranded DNA. Each chromatid within a chromosome contains the same set of genes. Each chromosome contains both DNA and protein. There are 12 chromosomes.
What are the differences and relationships between alleles genes and chromosomes?
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. Chromosomes occur in pairs so organisms have two alleles for each gene — one allele in each chromosome in the pair.
What is the main difference between gene and allele?
Gene is defined as a section of DNA that encodes for a certain trait. An allele is defined as a variant form of a gene. It determines an organism’s genotype. It determines an organism’s phenotype.
What is the difference between chromosome and DNA?
A chromosome is a long chain of DNA molecules that contains part of all of the genetic material of an organism. DNA is a fundamental molecule that carries the genetic instruction of all living organisms. DNA is packed into chromosomes with the help of special proteins called histones.
Which of the following best describes the structural relationship between genes chromosomes and DNA?
Which of the following best describes the structural relationship between genes, chromosomes and DNA? Each chromosome consists of a single long DNA molecule, and each gene on the chromosome is a particular segment of that DNA.
How do genes differ from chromosomes?
Genes are the basic units of heredity and are located on chromosomes. Genes are sections of DNA, whereas chromosomes are the structures that DNA folds into before cell division. Each human somatic cell contains 23 pairs of chromosomes.
How many chromosomes are in a gene?
Genes are contained in chromosomes, which are mainly in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.
What is the difference between a chromosome and a gene?
• Gene is a fraction of the DNA strand while chromosome is the whole strand of DNA. Therefore, it could be said that chromosomes are longer and larger than genes.
What is DNA vs chromosome?
Main Difference – DNA vs Chromosome. The key difference between DNA and chromosome is that DNA is the unorganized structure of the carrier of genetic information in most organisms and chromosome is the most organized structure of DNA with histones within a cell. Further, DNA stores the genetic instructions whereas chromosomes allow the gene regulation of a DNA strand.
