Genetics is the study of genes and heredity, while DNA (deoxyribonucleic acid) is the molecule that contains the genetic information in living organisms. DNA is made up of genes, which are the units of heredity that determine traits by providing instructions for making proteins. Genetics explores how these genes are inherited, expressed, and mutated, providing insights into the role of DNA in shaping an organism's characteristics.
Genes are smaller than DNA
DNA is the substance which exists in the form of long strands of 'bases' (4 different types) which combine to form 'codes' to enable cells to grow and function as appropriate for each species, and the body part within each organism. 'Genes' are chunks of code, each of which forms part of a strand of DNA. Each strand of DNA is called a Chromosome, and the number of strands/chromosomes is fixed in each species, but varies from one species to another. Each organism has 2 sets of chromosomes, one from each parent. Where an organism has different genes from each parent (say brown eyes from one parent, blue eyes from the other parent), one or the other gen will be dominant, although it does get more complicated than that - you need to read some genetics books). In this example, brown is dominant to blue because the brown eye gene actively makes pigment, wheras the blue gene simply doesn't, or at least, not much. Therefore in a person with one brown gene and one blue gene, the brown gene will make enough pigment to give brown eyes, although they might be a lighter shade of brown that a person with 2 genes actively producing pigment. (Before anyone says, yeah, yeah, grossly simplified I know, just trying to get the basic concept across.)
Every cell in a body has the whole set of DNA for the species, but there are mechanisms, governed by HOX genes, which normally regulate things so that each cell only activates those genes relevent for where it is in the body. For example, all heart muscle cells carry the genes for (say) eye colour, but they only actually use the genes relevent for being a heart muscle cell.
You may have seen those breeds of fancy chickens & pigeons (at an agricultural show or petting zoo perhaps?) with feathery feet. This is an example of how selective breeding has managed to over-ride normal HOX gene controls, by bringing feather growth genes which would normally only be active on wing cells on legs as well.
DNA (Deoxyribonucleic Acid) consists of nucleotides. Each Nucleotide contains a Nitrogenous base. The sequences of nucleotides is a gene in basic terms. Overall the sequence of the DNA nitrogenous bases are the general code for protein/amino acids in cells. The DNA is copied through transcription and creates RNA. The mRNA goes into the cytoplasm and compines with a ribosome. This ribosomes assists in the synthesis of proteins.
DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information. DNA (deoxyribonucleic acid) is the double helix molecule which encodes many millions of different combinations of nitrogenous bases which make up a genotype. A gene is a section of this. Genes are masses of DNA that direct certain things - think of genes as orders in the military and DNA as the words in those orders.
genes are the segments of dna. dna is the whole genome and it contains coding sequences as well as non-coding sequences and the coding sequences are the genes. A gene codes for a protein. A full single gene can be present at one place on dna, or fragments or parts of a single gene may be present at different locations on dna with non-coding region in between.
A DNA paternity test can be used to trace men's genetics by analyzing specific genetic markers to determine biological relatedness between individuals. This test compares the genetic information of the man with that of the child to establish a father-child relationship with a high degree of accuracy.
The study of genes and DNA is known as genetics. It involves examining how traits are passed down from parents to offspring through DNA, and how variations in genes can lead to differences in characteristics among individuals. Genetics plays a crucial role in understanding inheritance, evolution, and various genetic disorders.
The field of biology that focuses on heredity and DNA is genetics. Genetics involves the study of genes, genetic variation, and inheritance patterns in living organisms to understand how traits are passed from one generation to the next.
It is someone who helps to find cures for diseases, and does stem cell research, DNA pathology, splices DNA, and helps to manipulate DNA. There are many many more functions and applications a Genetics research scientist does on a regular basis, but this is the gist of it.
The type of genetics that studies genes and chromosomes is called molecular genetics. This field focuses on how genes are structured, how they function, and how they are regulated within the DNA molecule.
genetics correlate with drug dependence
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
No, DNA is the substance from which genes are made. Genetics is the study of genes and their expression.
Chromosomes are in DNA (Deoxyribo Nucleic Acid)

DNA molecules are arranged by genetics
The relationship between Cancer and DNA cancer begins when mutations distrupt the normal cell cycle, causing cells to divide in an uncontrolled way.

White peoples dna. They live longer. it is in there genetics.
