What else can I help you with?
Are there more chromosome than genes?
No. Humans have 46 chromosomes " beaded " with about 25,000 genes.
Why did scientists expect that human would have more genes than they actually do?
Scientists initially expected humans to have more genes because they underestimated the complexity of gene regulation and the role played by non-coding regions of DNA. When the human genome was sequenced, it was found that we have around 20,000-25,000 genes, far fewer than the 100,000 or more that was originally predicted. This discovery highlighted the importance of gene regulation and alternative splicing in generating diversity from a relatively small number of genes.
What is the simple subject in the sentence By studying human genes scientists hope to learn more about how to prevent and cure hereditary disease?
Human Genes
Is it true that the more genes you have the more complex of an organism you are?
Not necessarily. The number of genes does not directly correlate with complexity. For example, humans have around 20,000-25,000 genes, while some plants have a lot more. Complexity is more influenced by how genes are regulated and interact with each other.
How long a human survive with thalassemia and with the recessive genes?
Those with thalassemia can expect to live until they are 50 or more.
How do similarities in genes show that humans and yeasts share a common ancestry?
Similarities in genes between humans and yeasts indicate that they share a common ancestor because these similarities suggest that the genes have been passed down from a common evolutionary origin. Genes that perform similar functions in both organisms provide evidence of a shared genetic and evolutionary history. The more similar the genes are, the more closely related the organisms are believed to be.
What do scientists study to learn more about early humans?
Scientists study fossils, ancient tools, and DNA to learn more about early humans. By comparing and analyzing these sources of evidence, scientists can piece together information about the behavior, lifestyle, and relationships of our ancestors.
What are scientists more likely to learn from transgenic animals than from transgenic bacteria or trangenic plants?
How humans genes function. Animal biology is much more similar to that of humans than the others. This means that animals and humans (we are animals BTW) share a more recent genetic relative than the with the other two types of organisms. All life is related, that's why studying bacteria and viruses is very interesting. But from a human medicine standpoint animal studies are the most useful. Yhin Ramirez
What percent of genes are found common between chimps and humans?
The common quote is 98.5% genetic relatedness between humans and chimps. This is based on the shear number of similar genes. However, this number does not take into account gene duplication and the specific proteins produced by these similar genes. If these are accounted for, the number is more like 94%. Despite this, chimps are still our closest living relatives. See the links below for the more accurate figure.
How many genes do homo sapiens have?
~ 25,000 genes but Scientist lower this number as more is known.
When will be first experiment on humans to stop all genes of aging?
It is difficult to predict when the first experiment on humans to stop all genes of aging will take place, as such a development would need thorough testing and ethical considerations. Research is ongoing in the field of aging and genetics, but more time and studies are needed before reaching a point where interventions on all aging genes would be feasible in humans.
What do monkeys have to do with science?
By using monkeys, scientists can find out more about primates and the evolution of humans (cause monkeys are related to humans).
