What is the name given to cancer-causing genes?

Pathogens.


How can poor genes lead to extinction?

Poor genes can lead to extinction by causing lives to become shorter due to higher incidences of death by disease or weakness. These poor genes combine with other poor genes to create people or animals that are unable to live long and healthy lives.


Do autosomes have lethal recessive genes?

Yes, autosomes can carry lethal recessive genes. These genes can result in lethal genetic disorders when a person inherits two copies of the mutated gene, one from each parent, causing the disorder to manifest.


In fruit flies eye color is determined by?

Eye color in fruit flies is determined by the combination of genes they inherit, specifically genes located on the X chromosome. Mutations in these genes can lead to changes in eye color, with different alleles causing variations in pigmentation. The interaction of these genes ultimately determines the specific eye color of a fruit fly.


What is a organism that carries disease transport genes into a host cell refers to the term?

A vector is an organism that carries disease-causing genes into a host cell, allowing the genes to be incorporated into the host's genome. This process often occurs in genetic engineering and gene therapy techniques.


What change in genes or chromosomes that causes a new trait to be inherited?

Mutations create variation in the gene pool by causing new traits to appear


How does the gene lead to the color?

Genes carry information relating to physical traits, such as eye and hair colour. If the environment is correct, these genes will be expressed - causing the production of certain colour pigments in the eye and/or keratin in hair in order to produce a colour.


Explain how the bacteria in griffith's experiment were transformed?

The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.


What does recessive albinism mean?

An Autosomal recessive pattern is one in which certain genes of the X sex chromosome are turned off, autosomal is in reference to the X chromosome and the fact that the genes are turned off is indicated by the recessive. So in the case of Albinism the pigmentation genes in the X chromosome are turned off causing the various side effects.


Transcription of the structural genes in an inducible operon?

In an inducible operon, the structural genes are transcribed only when an inducer molecule is present. The inducer molecule binds to the repressor protein, causing it to be released from the operator region. This allows the RNA polymerase to bind to the promoter region and initiate transcription of the structural genes.


What genes have been implicated in causing lissencephaly?

The first gene causing lissencephaly, LIS1, was identified in patients with Miller-Dieker syndrome, a genetic syndrome caused by deletions of chromosome 17 that is a combination of lissencephaly and other facial deformities


What prevents e coli from expressing the lac genes in its DNA all of the time?

The lac genes in E. coli are regulated by the lac operon, which is controlled by a repressor protein. The repressor binds to the operator region of the DNA, blocking the transcription of the lac genes. When lactose is present, it binds to the repressor, causing a conformational change that releases the repressor from the operator, allowing for the expression of the lac genes.
