_______ are regions in an organism's DNA that encode information about heritable traits.
A gene is the region of DNA which encodes heritable trait. A gene is the basic unit of hereditary in living organisms. A gene comprises short regions of DNA which encodes for a particular protein.
Gene can acquire mutation in their sequence leading to different variants called alleles in the population. Alleles may be more than two in number in population but in an individual they cannot be usually more than two.
Gene is first transcribed into mRNA then it is translated into protein. Thus gene is expressed.
_______ are regions in an organism's DNA that encode information about heritable traits.
The continuity of life is based on heritable information in the form of DNA. Explain how the process of mitosis faithfully parcels out exact copies of this heritable information in the production of genetically identical daughter cells.
How does the major groove encode information about the base pair sequence of DNA? Please explain throughly, I will rate well for an informative answer!
Why is heritable variation among individuals an important factor for natural selection? All the hereditary information of an organism, including the totality of the DNA (I.e. coding and noncoding regions alike) is called
IS. The scientific meaning of the term "evolution" is: a) Any change in the heritable traits within a population across generations @ The creation of new traits to meet an environmental need An individual adapting to their environment during their lifetime
Natural selection is differential success in reproduction from interaction between individuals that vary in heritable traits and their environment? True or False
I need help with this one. Changes in heritable traits in a population through multiple generations is called Multiple Choice O heredity mitosis phenotype evolution genotype.
Topic 6. DNA Replication, Repair and Recombination Some retrotransposons and retroviruses integrate preferentially into regions of the chromosome that are: (a) packaged in euchromatin and; (b) located outside the regions of genes that encode the amino acid sequences of proteins. Why might these mobile genetic elements have evolved this strategy?
compare selection and mutation 1. DNA molecules in the cells exist as a........ 2. DNA carry the information to build and maintain the cells life by four letters of genetic language True False 3. The term phenotype is used to describe all of the organism's genetic information True / False 4. All of the organism DNA encode genes True/ False 5. Bacteria have one chromosome which is circular structure associated with proteins (no histones) True False 6. In the process...
Mutations are heritable changes in DNA. They are essential to the study of genetics and are useful in many other biological fields. How are mutations used to help in understanding basic biological processes? What is the SOS system and how does it lead to an increase in mutations? What is the purpose of the Ames test? How are his- bacteria used in this test?
Repin ma regions associated with a trait by GWAS are often nS containing no transcribed/translated genes, because 3- they are centromeric. they encode transcription factors they contain no DNA. there are only about 25,000 genes. e. they are probably Neanderthal DNA remnants.
