DNA and RNA are made up of monomers called nucleotides. - DNA and RNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine. - DNA and RNA both have a phosphate groups in their nucleotides. Sometimes called phosphoric acid

<span>Structurally, DNA and RNA are nearly identical. However, there are fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine. DNA is usually double-stranded (double helix) and most cellular RNA is single-stranded (single helix). In DNA, the common organic bases are adenine, guanine, cytosine, and thymine. In RNA on the other hand, the common organic bases are adenine, guanine, cytosine, and uracil. Transcription is the process of converting DNA into a correlative RNA code, or in other words, making an RNA copy of a gene sequence. This copy is called a messenger RNA molecule, or mRNA. It is basically a large group of RNA molecules that transport genetic information from the DNA to the ribosomes. The mRNA does this by leaving the cell nucleus and entering the body of the cell, which is the cytoplasm. During translation, protein is assembled when the ribosomes translate the sequence in the arriving mRNA. They then bring in the appropriate amino acids needed to complete the protein synthesis. Together, transcription and translation are referred to as gene expression. RNA consists of three major types: mRNA (messenger), tRNA (transfer), and rRNA (ribosomal). As said before, mRNA serves as temporary copies of DNA information. tRNA on the other hand, are the ones that transfer the amino acids to ribosomes in order that they can be assembled into protein. Finally, there is rRNA, which has an entirely different function altogether, as a molecular component of the ribosome. In short, rRNA is essentially the cell’s main protein factory. While it does not make proteins directly, it does produce and link together assemblies of amino acids (polypeptides) that have the job of making them. * Sorry I just had a paper on this and feel like spouting a whole bunch of info</span>

ollegr [7]

Answer:

This question is incomplete; the complete part is:

Which of the following best explains the reactions of these enzymes?

A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.

B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.

C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.

D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.

The answer is A

Explanation:

In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.

Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).

On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.

What is the role of tRNA?

nirvana33 [79]

Answer:

The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation

Explanation:

tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.

tRNA then moves to the P site and a new tRNA bind to the A site of ribosome and brings a new amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA recognizes a termination or nonsense codon

Fraternal twins are _______ similar genetically than are other brothers and sisters.

Sonja [21]

The correct term to fill in the blank is "no more". Fraternal twins are no more similar genetically than are other brothers and sisters. They are also known as dizygotic twins since they are formed from 2 different amniotic sacs and placentas which means they are totally developed from two different eggs and being fertilized by different sperm cells. So, they have different characteristics. The genetic code they would have would be the same as any other sibling. So, they are not identical. The other type of twins is called the monozygotic or the idetical twins. This type would have the same genetic codes.
