Answer:
Bodies of ice and rock that orbit the Sun and produce a coma and tail of vapor and dust when near the Sun
Explanation:
So if you go to the NASA dictionary it states:
Comet- cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.
So it is most definitely the second option
Have a great day :D
Answer:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Explanation:
Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.
In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the
mRNA sequence from this DNA during transcription will be:
AUG UCC CAC GAU GGG UGA
From this mRNA sequence, the peptide chain that will result following translation is:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.
Somatic mutation - not passed from generation to generations, occurs in body cells.
Both- changes in DNA.
<h3><u>Explanation:</u></h3>
Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.
Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.
