What are the different types of DNA that make up the human genome (one example ""DNA transposons"") Name at least 5 types.
Diano4ka-milaya [45]

Answer:

The correct answer will be-

1. Mobile elemests- LINEs and SINEs

2. Exons

3. Non-coding RNA genes

4. Introns

5.  Repetitive DNA sequence

Explanation:

The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.

The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.

The non-coding sequence includes the  Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.

Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.

someone has their blood tested and finds that their blood sugar level is 138. this is equivalent to 1.38%. How much glucose is i
disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.
