B. plant cells do not have any centromeres in their cells. Also plant cells have a cell plate, but animal cells do not.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
- How to bring the information from the nuclear DNA to the place of protein synthesis?
- How to convert this DNA information into amino acids and then into proteins?
Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
<h3>How to bring the information from the nuclear DNA to the place of protein synthesis?
</h3>
The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
<h3>How to convert this DNA information into amino acids and then into proteins?</h3>
Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.
Answer:
Tropical forest recieve large amounts of rain every year, about 60mm at least. Tropical forests also have no dry season. Plants that grow in this type of forest must adapt to the extremely wet conditions. For instance, trees in this type of forests grow long and thin trunks to reach the sunlight easier.
Coniferous forest typically have long winters and high precipitation levels. However, unlike Tropical rainforests, Coniferous forests have diverse seasons and no all year rainfall. It still rains a lot though. For example, trees in this forest grow relatively short and thick trunks to protect from the cold winters months.
Explanation:
No, what determines a dominant gene is how many copies of that gene exists within the parent. This doesn't mean it will be the most common because of recessive genes. It doesn't matter how many copies a dominant gene has, a recessive gene can still appear in the offspring.
