Describe the structures and functions of the digestive system

REY [17]

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

Skin cells reproduce once every day. Liver cells reproduce once every year. Why do you think skin cells reproduce more often?

Artyom0805 [142]

Skins cell reproduce more because let’s say for example you get hurt and the skin falls off in order to protect you it grows back immediately

The secondary structure of proteins results because of _____ bonding between molecules in the protein molecules' backbone.

topjm [15]

Answer:

Hydrogen bonding

Explanation:

The newly synthesised proteins as a result of the process of translation are linear structures formed by linear arrangement of amino acids.

The linear structure of a protein is known as the primary structure which changes its conformation and take the shape of either the helix or the pleated sheet. This helical or pleated sheet structure is known as a secondary structure.

The secondary structure is formed due to the bond formed between the hydrogen of the carbonyl group and the amino group which form the backbone of the protein structure. The hydrogen bond causes the linear polypeptide to form spiral helical or bend pleated sheet.

Thus, Hydrogen bonding is the correct answer.

Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be

REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

T A T A T C T A C G G T C C G G C A T C G A T T T C G

So the RNA sequence for this will be:

A U A U A G A U G C C A G G C C G U A G C U A A A G C.

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.
