Deoxyribonucleic acid (DNA) is usually called the blueprint of life. Deoxyribose is a monosaccharide that has a key function in the synthesis of deoxyribonucleic acid. One less oxygen-containing hydroxyl group occurs in deoxyribose sugar. Nucleic acid, d…

DNA as the Genetic Material

DNA, or deoxyribonucleic acid, is a long polymeric nucleic acid molecule discovered in the late 1930s. It is a polymer; a long chain-like molecule made up of several monomers connected in a sequence. It possesses certain characteristics that qualify it a…

Genetics

The significant branch in science which involves the study of genes, gene variations, and the organism's heredity is known as genetics. It is also used to study the involvement of a gene or set of genes in the health of an individual and how it prevents …

DNA Replication

The mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of its own is defined as DNA replication. The DNA molecules utilize a semiconservative method for replication.

Chapter 6.2, Problem 1MQ

Students have asked these similar questions

Describe how the shape and size of nucleotides are important in the structure of double-stranded DNA.

Consider the following DNA sequence:CATGTGTAGTCTAAAa. Write the sequence of the DNA strand that would be repli-cated from this one.b. Write the sequence of the RNA molecule that would betranscribed from the DNA strand.c. State how many codons the sequence specifies.d. State how many amino acids the sequence specifies

If an RNA strand generates its complementary strand, thus producing a double helix, will a molecule of this be structurally identical to that of DNA? Explain.
