Could a single mutation cause barbules to form on feather barbs?

Although the cause of barbules to form on feather barbs doesn't sound like a difficult change in evolution, it would likely take more than just a single mutation for such an evolutionary change to occur. Most likely, it would take many mutations.


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.

What would happen if we didn't have junk DNA?

If we didn't have junk DNA any mutation would cause damage to essential sequences of DNA and likely kill the host. It would be to dangerous to be in the sun because uv radiation cause mutations. However most of the mutation occur in the non essentioal junk DNA thus protecting essential DNA.

How many amino acids would this protein have if a mutation occurred and the 7th dna base pair of the dna strand was changed from a-t to t-a?

This mutation would cause a frameshift mutation, shifting the reading frame of the DNA sequence. Most likely, this would lead to a completely different protein being translated, resulting in a protein with a different sequence of amino acids from the original protein. The number of amino acids would depend on the specific changes in the protein sequence caused by the frameshift mutation.


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.


Which kind of mutation is most likely to produce a protein with one extra amino acid?

A frameshift mutation, such as an insertion of one nucleotide, is most likely to produce a protein with one extra amino acid. This type of mutation shifts the reading frame of the genetic code, leading to a change in the entire sequence of amino acids after the mutation site.
