What are the two parts of the backbone of DNA?
The two parts of the backbone of DNA are sugar and phosphate molecules. These molecules alternate in a pattern, forming the structure of the DNA double helix.
What factors is most likely caused a mutation in DNA?
There are two main factors that cause a mutation in DNA. These factors include: the DNA fails to accurately copy itself and external influence cause a breakdown in the DNA.
Can be described as alternate forms of a particular gene Chromatids Alleles Chromosomes DNA molecules?
Alleles are alternate forms of a particular gene, which can lead to variations in traits. Chromatids are duplicated copies of a chromosome that are joined at the centromere. Chromosomes are structures composed of DNA and proteins that contain genes. DNA molecules are the chemical building blocks that make up chromosomes and carry genetic information.
What factors that can affect a person appearance?
Genetic factors(DNA)
What is a alternate forms of a particular gene called and they rise as a result of what?
Alternate forms of a gene are called alleles. These alleles arise as a result of mutations in the DNA sequence of the gene.
Name two molecules which alternate to make the upright or side portion of a DNA molecule?
The two molecules that alternate to form the backbone of a DNA molecule are deoxyribose sugar and phosphate groups. These molecules form a repeating pattern along the length of the DNA strand, with the nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the deoxyribose sugar molecules.
What are some factors that can cause DNA damage during cell division?
Factors that can cause DNA damage during cell division include exposure to mutagens like radiation or chemicals, errors in DNA replication, and oxidative stress from metabolic processes. Additionally, environmental factors such as pollution, UV radiation, and certain lifestyle choices like smoking can also contribute to DNA damage.
Can outside factors damage DNA?
Yes, outside factors such as ultraviolet radiation, certain chemicals, and ionizing radiation can damage DNA by causing mutations or breaks in the DNA strands. These damages can lead to errors in DNA replication or repair, potentially leading to diseases like cancer or genetic disorders.
What factors influence a person's appearance?
DNA
What specific sequences do transcription factors bind to on DNA?
Transcription factors bind to specific DNA sequences called enhancers and promoters to regulate gene expression.
What can inhibit transcription by blocking the binding of positively acting transcription factors to the DNA?
The binding of negatively acting transcription factors, chromatin remodeling complexes, DNA methylation, or histone deacetylation can inhibit transcription by preventing the binding of positively acting transcription factors to the DNA.
DNA mutations can lead to genetic disorders diseases or even the death of an organism Which of the following factors is most likely to cause a mutation in DNA?
Exposure to harmful environmental factors such as radiation, chemicals, or toxins is most likely to cause mutations in DNA. These factors can damage the DNA structure and lead to errors in the replication process, increasing the risk of genetic disorders or diseases in organisms.
