zepelin [54]3 years ago
6 0

Answer:

Does Every Cell in the Human Body Contain the Same DNA? With few exceptions, all cells in a person's body have the same DNA and genes. As cells divide and grow different genes are expressed, resulting in different cell types.

Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change
Nata [24]

Answer:

The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.

Explanation:

As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.

Answer:

1. DNA

2. Nucleus

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific  tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.
