There are three types of genetic disorders: monogenic, multifactorial and chromosomal. Monogenic disorders A mutation occurs in the DNA sequence of a single gene. Most monogenic disorders are rare diseases such as Pompe disease and hemophilia. Multifactorial disorders These genetic diseases are cause...

The idea of genes as beads on a DNA string is fast fading. Protein-coding sequences have no clear beginning or end and RNA is a key part of the information package, reports Helen Pearson. This is a preview of subscription content, access via your institution Relevant articles Open Access ...
Genomics is the study of DNA sequence and how it contributes to the genotype and phenotype of organisms and individuals. We now have an unprecedented ability to analyze the pig genome and we can anticipate that genomics will have an increasingly large impact on genetic improvement and pork ...
Since the sequence of bases carries the instructions for making proteins and also regulates gene functions, the ability to read genetic sequences is enormously valuable to biological research. Because differences in DNA and RNA sequences can distinguish organisms down to specie...
Since the sequence of bases carries the instructions for making proteins and also regulates gene functions, the ability to read genetic sequences is enormously valuable to biological research. Because differences in DNA and RNA sequences can distinguish organisms down to species and individual levels,...
Epigenetics is defined as the study of heritable regulation of gene activity that is not determined by the genetic sequence. Our genes are the combination of four bases or parts labeled A, C, G and T, which when disrupted the call mutations. Today we know that genes are controlled by other...
What is a genetic mutation? Genes: Genes are DNA sequences which have biological function. Most genes are for polypeptide molecules however some genes encode RNA species such as ribosomal RNA. Answer and Explanation:1 Genetic mutations are alterations in the sequence of bases in a gene. Genetic...
(genes) directly dictate amino acid sequences is known ascolinearity(Figure 1). Scientists have confirmed that colinearity is a regular occurrence among many viruses, like the ones Benzer studied, as well as amongbacteria. However, it turns out that colinearity is the exception, not the rule, ...
A promoter sequence is a genetic sequence which governs the transcriptional activation of a certain gene. Generally, promoter sequences bind...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
