8. Produces sperm and reproductive hormone - Testis

Explanation:

This question is asking to correctly match certain digestive organs with their respective function. The organs and their function are as follows:

- Small intestine: Small intestine is the major organ that digests food chemically, and also absorbs nutrients and minerals from food.

- Stomach: This breaks down and physically digests food.

Which of the following statements regarding restriction enzymes is NOT true? See Section 15.1 (Page 554) . Which of the followin

irinina [24]

Answer:

Most restriction enzymes recognize sequences of 20-25 bp in length

Explanation:

Sequences of DNA that are recognized by restriction enzymes are called recognition (or restriction) sites are usually are between 4 and 8 bases long. Many of them are palindromic, which means that they are the same when you read it backwards and forwards (mirror-like).

Restriction enzymes are endonucleases, which means they cut phosphodiiester bonds within DNA. These enzymes are from prokaryotic organisms (archea and bacteria) which use them as defending mechanism against viruses. Prokaryotes protect their own DNA via methylation, performed by methyltransferase.
