Digestion of nutrients begins in varying places. For carbohydrates it begins in the ________, for proteins in the _____ and for
aniked [119]

The correct answer for this question is 'Mouth, Stomach, Small Intestine'.

what is Digestion?

Digestion is the process of breakdown of large insoluble food molecules into small water soluble molecules for absorption is called as digestion

The digestion of Carbohydrates usually takes place in small intestine but the digestion process starts in the mouth by the help of salivary amylase present in the saliva. The complete digestion takes place in small intestine with the help of pancreatic enzymes called α-glucosidase and amylase

The protein digestion takes place in the stomach as the Ph conditions are favourable for the digestion of proteins the stomach walls release pepsin enzyme for the synthesis of proteins the protein digestion also takes place in small intestine.

Lipids are mostly digested in the small intestines by the help of bile and pancreatic lipases the lipids get  broken down to fatty acids and monoglycerides for easier absorption this process of breaking down fats is called as Emulsification

. For the following give the mRNA, tRNA and amino acid (a.a.) sequence that will be created:
alexdok [17]
<span>mRNA: UACAUGGCCUUACGCUAA tRNA: AUG UAC CGG AAU GCG AUU a.a: Tyrosine, Methionine, Alanine, Leucine, and Arginine DNA has 4 different bases, they are Adenine (A), cytosine (C), guanine (G), and Thymine (T). RNA also has 4 bases with three of them being identical to the DNA bases and Thymine being replaced with Uracil (U). These bases are generally represented by the 1st letter of their names. Each of the bases will join with a complementary base, so A always pairs with T or U, and C will pair with G. So to create the mRNA, simply replace every A with a U, every C with a G, every G with a C, and finally, every T with a A. So mRNA: UACAUGGCCUUACGCUAA Now for tRNA, there's a slight twist. It only comes in 3 base codons, You won't find a sequence of tRNA other than in 3 base codons. And each of those codons will be uniquely paired with an amino acid. In the ribosomes, the mRNA will be sequentially scanned 3 bases at a time allowing for a matching tRNA sequence to bind to the exposed 3 bases, this will cause the next amino acid to be bound into the protein being constructed. So split the mRNA into 3 base sequences and calculate the complement to get the tRNA. A simple shortcut is to look at the original DNA sequence and simply replace a T bases with U. So tRNA: AUG UAC CGG AAU GCG AUU Notice the spaces every 3rd base. THIS IS REQUIRED. These is no continuous length of tRNA. You'll only find it in 3 base lengths and each of them will be bound with an amino acid. For the amino acid that's coded to the RNA, you'll need to use a lookup table in your text book, or one you can find online. Then it's a simple matter of matching each 3 base sequence to the amino acid. For the sequence given we have: AUG - Tyrosine UAC - Methionine CGG - Alanine AAU - Leucine GCG - Arginine AUU - STOP Notice the AUU doesn't decode to a specific amino acid. It instead indicates to the ribosome to stop the production of the protein. So the amino acid sequence for the originally given DNA sequence is: Tyrosine, Methionine, Alanine, Leucine, and Arginine.</span>

Why might knowledge of the gene and protein sequences of a species be useful in classifying that species? (4 points)
lara [203]

Answer:

It would make it possible to compare that species to other species at a level deeper than outward appearance

Explanation:

The proteins like hemoglobin and enzymes can be studied to see whether organism which are similar in form can also be related to each other. Its differences found in these proteins' amino acid sequences will present how closely or distantly related an organism is to another.
