Answers
G and C pair.
These are the only possible pairs so the answer is the second pair and the fourth pair
The nucleotides which base pairs together in the DNA helix are adenine(A) to the thymine (T) and Cytosine(C) to the Guanine (G). A purine always base pairs against a pyrimidine.
What are nucleotides?Nucleotides are the monomeric units of the genetic material i.e., DNA present in the nucleus of cell. Nucleotides are made up of three components which include a nitrogenous base, a deoxyribose sugar in case of DNA or a ribose sugar in case of RNA, and a phosphate group moiety.
The nitrogenous bases are of two types on the basis of their structures: Purines and Pyrimidines. Purines are double-ring structures which contain an imidazole ring attached to a pyrimidine ring. This include Adenine and Guanine. Pyrimidines are single-membranous structures which are similar to pyridine. Pyrimidines include cytosine, thymine and uracil. In DNA, thymine is present whereas in RNA, uracil is present.
A purine always base pairs with a pyrimidine. In case of DNA, an adenine forms two hydrogen bonds to base pair with thymine and vice versa whereas guanine forms three hydrogen bonds while pairing with cytosine residues and vice versa.

Which of the following is true about RNA?
tRNA brings in an amino acid and bonds with mRNA
mRNA carries the code of rRNA to the nucleus.
mRNA is made from tRNA during transcription.
rRNA helps tRNA make a copy of the DNA gene.
Answers
Answer:
the right answer is
tRNA bonds with mRNA, bringing in amino acids.
Explanation:
Ribonucleic acid is a single-stranded structure. The true statement is tRNA brings in an amino acid and bonds with mRNA. Therefore, the correct answer is option 1.
The Transfer RNA, or tRNA, transports amino acids to the ribosomes, the cell's protein-making factories, during the synthesis of proteins. An anticodon, which is a particular set of nucleotides on each tRNA molecule, is complementary to the codon on the mRNA (messenger RNA) molecule. From the DNA in the nucleus to the ribosomes in the cytoplasm, the mRNA transports the genetic information.
The tRNA with the complementary anticodon brings in the exact amino acid that is coded by that codon when the ribosomes read the codon on the mRNA. In order for the ribosomes to assemble the amino acids into a protein chain in the proper sequence, the tRNA molecule then forms a connection with the mRNA.
Therefore, the correct answer is tRNA brings in an amino acid and bonds with mRNA, i.e. Option 1.

(15 points) Aerobic cellular respiration takes place in the mitochondria and uses oxygen to break down glucose. However, when cells need large amounts of energy and no oxygen is available, anaerobic respiration can take place in the cytoplasm. What is the difference in the products of aerobic and anaerobic cellular respiration?
Answers
Answer:
There are two kinds of respiration: Aerobic and Anaerobic. ... Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.

ribose sugar is used to make nucleic acid however, it is not formed directly in photosynthesis but is formed from glucose. How does glucose form ribose?
Answers
Answer: Ribose is synthesized from glucose and other monosaccharide molecules in living cells by a process known as pentose phosphate pathway. The pentose phosphate pathway is a series of chemical reactions taking place in the cytosol of cells.
Glucose forms ribose through a series of chemical reactions, including the conversion of glucose-6-phosphate to ribose-5-phosphate.
What is ribose sugar?Ribose sugar is a five-carbon sugar molecule that is an important building block of nucleic acids, such as RNA and DNA. It is a type of carbohydrate and is structurally similar to glucose, but has a different chemical arrangement.
Ribose is synthesized in the body through a series of metabolic reactions, starting with glucose, and is also found in some natural sources such as ribose supplements. It is important for the production of energy in cells, the regulation of gene expression, and the synthesis of nucleotides.

suggest why digestion (the breakdown of large macromolecules) is largely performed by extracellular enzymes
Answers
Answer:
Enzymes speed up the breakdown of macromolecules in food to small molecules
Explanation:
During digestion, the macromolecules that make up food are hydrolyzed by digestive juices to molecules of a size that allows their absorption through the lumen of the tract. In this way, proteins are divided into amino acids, carbohydrates into glucose and other monosaccharides, and fats into glycerol and fatty acids. Digestion and absorption take place mainly in the small intestine.The production of extracellular enzymes that, once released into the medium, degrade the substrate and then allow their diffusion / transport.
