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.

How does mutations occur during DNA replication and transcription?
During DNA replication, mutations can occur due to errors made by DNA polymerase when copying the DNA template. These errors can result in base substitutions, insertions, or deletions in the new DNA strand. During transcription, mutations can occur if RNA polymerase inserts the wrong nucleotide into the messenger RNA (mRNA) strand, leading to incorrect genetic information being transcribed from the DNA template.
Does transcription occur in DNA or RNA?
Transcription occurs in DNA to produce mRNA.
What are known as gene mutations and occur at a single point in the DNA sequence?
Gene mutations that occur at a single point in the DNA sequence are called point mutations. These mutations can involve substitutions of one nucleotide for another (missense mutation), insertion of an extra nucleotide (insertion mutation), or deletion of a nucleotide (deletion mutation). Point mutations can have various effects on the resulting protein, ranging from no impact to severe functional changes.
What type of base pairing occur during transcriptions?
the types that occur are complementary and antiparallel. For example, DNA A will pair with RNA U and DNA C will pair with RNA G.
Which in DNA often occur during replication. During which phase of the cells cycle do such mutations occur?
Interphase

How do birds get mutations?
Mutations are a rare but ordinary occurance in DNA RNA replication. Radiation and chemical damage.
What is a facets of life?
Mutations that occur in DNA
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.
Where is the process of making rna from DNA occur?
rna protein chains
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase
Mutations occur because of?
errors in DNA replication
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
What are the differences between single-stranded DNA and RNA?
Single-stranded DNA and RNA are both nucleic acids, but they have some key differences. DNA is typically double-stranded, while RNA is single-stranded. DNA uses the base thymine, while RNA uses uracil. Additionally, DNA is more stable and less prone to mutations compared to RNA.
Do most mutations occur when DNA is being replicated?
yes
Does transcription occur in DNA or RNA?
Transcription occurs in DNA to produce mRNA.
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
