What are the two base color genes for horse?
The base color is black/red factors, controlled by the Extension gene. A horse with one or two copies of the Extension gene (Ee or EE) will have black factors. A horse with no copies of the Extension gene (ee) will be chestnut.The Agouti gene acts on the Extension gene by limiting where the black factors are displayed, into points such as the legs, mane, tail, muzzle, and ears. A horse with at least one copy of the Extension gene that doesn't not have a copy of the Agouti gene will be black, provided that no other gene modify the color. One or two copies of the Agouti gene in combination with the Extension gene will result in a bay horse. A chestnut horse (no copies of the Extension gene) can have copies of the Agouti gene, but it will not affect the horse's color, as the horse has no black factors for the Agouti gene to limit.
List the major factors that influence bone growth and development?
nutrition and gene factors
What do regulatory elements in gene control interact with?
Regulatory elements in gene control interact with transcription factors, which bind to specific DNA sequences to either enhance or inhibit gene expression. These interactions help regulate when and to what extent a gene is transcribed into messenger RNA.
How does a healthy gene differ from a gene that causes hemophilia?
A healthy gene does not have mutations that disrupt normal blood clotting factors. A gene that causes hemophilia has mutations that affect the production or function of blood clotting factors, leading to difficulty in blood clotting and increased risk of bleeding.
What is the difference between sigma factors and transcription factors in gene regulation?
Sigma factors are specific proteins in prokaryotes that help RNA polymerase bind to the promoter region of a gene to initiate transcription. Transcription factors, on the other hand, are proteins in eukaryotes that regulate gene expression by binding to specific DNA sequences and influencing the activity of RNA polymerase. In summary, sigma factors are specific to prokaryotes and help initiate transcription, while transcription factors are found in eukaryotes and regulate gene expression.
Do transcription factors bind to enhancers to regulate gene expression?
Yes, transcription factors bind to enhancers to regulate gene expression by controlling the rate of transcription of specific genes.
What is the role of transcription factors in regulating gene expression by binding to enhancers?
Transcription factors are proteins that control the activity of genes by binding to enhancers, which are specific DNA sequences that enhance gene expression. By binding to enhancers, transcription factors can either activate or repress the transcription of genes, thereby regulating gene expression.
What factors have kept gene therapy from becoming an effective treatment for genetic disease?
There are a number of factors which have kept gene therapy from becoming an effective treatment for genetic disease. The viral rectors are the main problems which might make gene therapy to cause diseases.
A short and simple definition of gene?
A gene is a part of the chromosome what is linked to your DNA it carries the proteins which make you, you! Factors that control traits.
Why did gene sneak into the infirmary?
Gene sneaked into the infirmary to retrieve some medical supplies to help his injured friend, Finny. He wanted to take care of Finny and support him during his recovery.
What role do activators, a set of transcription factors, play in regulating gene expression?
Activators, a type of transcription factors, play a crucial role in regulating gene expression by binding to specific DNA sequences near a gene and enhancing the transcription process. This helps to increase the production of mRNA, leading to higher levels of protein synthesis from that gene.
What would likely prevent DNA from producing the proteins coded by a gene?
Possible factors that could prevent DNA from producing proteins coded by a gene include mutations in the gene sequence, epigenetic modifications that block gene expression, improper regulatory signals, or environmental factors that disrupt the transcription or translation process.
