Define the term gene mutation​

Biology
2 answers:
lina2011 [118]3 years ago
5 0

Answer:

A gene mutation is an alteration of the nucleotide sequence of a gene. Gene mutations can be caused by errors in DNA replication during cell division by both mitosis and meiosis. In addition, gene mutations are caused by environmental factors such as UV and chemicals. These factors are called mutagens.

Which is a correct interpretation of the cladogram shown below?
nataly862011 [7]

A cladogram is an image or a diagram that shows us an evolutionary relationship between different organisms. Up at the top we find the different organisms and their names. Along the side is where we find their characteristics. Anything that is past each characteristic will have that characteristic as you move up the cladogram. This diagram also shows which organisms are most closely related to one another.



Please see the image for an example. In this example we can see that the Koalas evolved after the trout.



I hope this helps, Regards.

What results from the addition or deletion of nucleotides in any number except a multiple of 3?
eimsori [14]
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.

How does the oyster population
I am Lyosha [343]

Answer:

Analysis of the data shows that the ratio of floating algae to sea floor algae dramatically increased at the same time that oysters were removed from the Bay. ... (It is also possible to infer from the graph that high floating algae levels led to the decline in oysters.

Several groups of protists have variable modes of nutrition: Some species are photoautotrophs, whereas close relatives are heter
Radda [10]

Answer:

The endosymbiotic theory

Explanation:

Protists are the multicellular organisms which possess characteristics of both the prokaryotes and eukaryotes.

The protist can derive nutrition by either heterotrophic mode or photoautotrophic mode. This variation could exist within the same genus and same species.

This variation could be explained with the endosymbiotic origin of the organisms as some species could engulf the photosynthetic bacteria whereas some could have engulfed the chemosynthetic bacteria.

This can be observed in the green and red algae which depend on a different mode of nutrition belonging to the same group.

Thus, the endosymbiotic theory is correct.
