The human genome contains approximately 10 6 copies of an Alu sequence, one of the best-studied classes of short interspersed el
sesenic [268]

Answer:

3000

Explanation:

- Human haploid genome >>> 3 x 10⁹ base pairs >>> 3,000,000,000 base pairs

- Human haploid genome >>> 10⁶ copies >>>  1,000,000 Alu Transposable Elements

- Space between each Alu Transposable Element (TE) >>>

3,000,000,000 base pairs / 1,000,000 Alu elements  = 3,000 base pairs

Alu elements are highly repetitive DNA sequences that account for approximately 20% of the human genome. These sequences (Alu) are considered to be non-autonomous Transposable Elements (TEs) capable of transposing within the genome via an RNA intermediary.

Cortisol is a steroid hormone that can pass through the plasma membrane. Complete the flowchart describing the interaction of co
Vedmedyk [2.9K]

Answer:

The flow chart for the cortisol steroid hormone is as follows:

1. Cortisol passes through the plasma membrane into the cytoplasm.

2. Cortisol receptor complex form in the cytoplasm.

3. Cortisol receptor complex enter the nucleus where it binds to gene.

4. Cortisol receptor complex acts as transcription factor.

5. The tranacribed mRNA is translated into specific protein.

Explanation:

Cortisol is small which is hydrophobic steroid hormone which has the ability to move through the plasma membrane of the cells. In the target cells the cortisol binds with the intracellular receptor protein of the cytoplasm which further forms a hormone receptor complex. The hormone receptor complex further moves into the nucleus ad hence acts as a transcription factor which gets bind to the specific gene and thus, activates the transcription into mRNA. The mRNA which is generated subsequently translated into some specific proteins. Proteins which has been produced with response to the cortisol signal function to the stress response.
