It will affect protein synthesis. mRNA uses DNA (a gene) as a template and mRNA is a template to join amino acids together. If the DNA sequence (gene) is changed, the mRNA will be changed, and the polypeptides will be changed - usually with harmful consequences. Proteins produce phenotypes in organisms, so a mutation in DNA causes abnormalities.

How do DNA mutations affect cells?

Cells are dividing through the processes of Mitosis and Meiosis. DNA mutations directly affect cells by making them divide non-stop. This is known as Cancer. Proto-oncogenes, a gene involved in cell division mutates and becomes oncogenes that orders cell mechanism of division to go on continously even though the DNA found in a cell's nucleus is already damaged. this causes abnormal cell division.


What are the key differences between cis and trans mutations in genetic variations?

Cis mutations occur on the same strand of DNA, while trans mutations occur on different strands. Cis mutations affect nearby genes, while trans mutations can affect genes located far apart.

Ultraviolet radiation can cause mutations in the DNA of skin cells that have been overexposed to the sun This mutated DNA has no effect on future offspring because?

mutations in skin cells do not affect germline cells, which are responsible for passing DNA to offspring. Only mutations in germline cells can be passed down to future generations. Skin cell mutations typically only impact the individual with the mutation.


What DNA mutations are directly linked to inherited diseases?

Some common DNA mutations directly linked to inherited diseases include the CFTR gene mutation in cystic fibrosis, the BRCA gene mutations in breast and ovarian cancers, and the HTT gene mutation in Huntington's disease. These mutations can be inherited from one or both parents and increase the likelihood of developing the associated disease.


Can you tamper with DNA?

Not directly. Radiation can cause mutations in DNA. Excess heat (as in the case of a fever) can denature (destroy) the DNA sequence as well as other proteins which will usually result in cell death.


How can mutation affect the mRNA?

Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.


Does a DNA mutation always result in a change to the protein?

No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.


How does chemestry affect cancer?

Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.


What role does substitution in DNA play in genetic mutations and inheritance?

Substitution in DNA can lead to genetic mutations, which are changes in the genetic code. These mutations can affect how traits are inherited from one generation to the next. Substitutions can alter the instructions for making proteins, potentially causing genetic disorders or variations in traits.


Can mutations occur in DNA and rna?

Yes, mutations can occur in both DNA and RNA. In DNA, mutations can arise from errors during replication, environmental factors, or harmful chemicals, leading to changes in the genetic code. Although RNA is usually more stable and transient, mutations can still occur during transcription or due to viral replication processes. These mutations can affect gene expression and protein synthesis, potentially leading to various biological consequences.
