What is the difference between genes DNA and chromosomes?

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.

What is the difference between RNA and DNA in terms of nitrogenous base?

DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.

What are the differences between genes and DNA?

DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division. Genes are the DNA stretches which encode for specific proteins. Regulates the traits of an organism.

What is the difference between a gene and RNA?

A gene is composed of DNA that is “read” or transcribed to produce an RNA molecule during the process of transcription. One major type of RNA molecule, called messenger RNA (mRNA), provides the information for the ribosome to catalyze protein synthesis in a process called translation.

What is the difference between homozygous dominant heterozygous and homozygous recessive?

An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. People with CF are homozygous recessive.

What are the three basic differences between DNA and RNA?

So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.

What is the relationship between DNA and chromosome?

The chromosomes serve as the structure that holds the DNA. The DNA acts as a complete set of instructions that tells our bodies how to develop. Storing more data than any computer, each chromosome contains all the information needed to give you a base for your physical (and emotional) characteristics.

What is the difference between genegene and chromosome?

Gene is segment of DNA molecule made up of nucleotides. A mitotic chromosome consists of a centromere, pair of telomeres and an origin of replication. The position of each gene on a chromosome is called loci. Chromosome is a long strand of DNA containing many genes.

What are the similarities and differences between DNA and RNA?

DNA and RNA share the nitrogenous bases A, G, and C. Thymine is usually only present in DNA and uracil is usually only present in RNA. Only some of the genes in cells are expressed into RNA. The following are the types of RNA wherein each type is encoded by its own type of gene:

What is the Order of the nitrogenous bases in DNA?

The order of the nitrogenous bases – thymine (T), guanine (G), cytosine (C), and adenine (A), is crucial in determining the genetic code. Genes are formed by the order of the nitrogenous bases present in the DNA which is crucial for protein synthesis. The RNA is another nucleic acid that translates genetic information into proteins from DNA.

What is the structure of gene?

Gene is segment of DNA molecule made up of nucleotides. A mitotic chromosome consists of a centromere, pair of telomeres and an origin of replication. The position of each gene on a chromosome is called loci.
