What is DNA made up F?
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
What do the letters mean in DNA?
Genetic Code = The instructions in a gene that tell the cell how to make a specific protein. A, C, G, and T are the “letters” of the DNA code; they stand for the chemicals adenine (A), cytosine (C), guanine (G), and thymine (T), respectively, that make up the nucleotide bases of DNA.
What is Acgt in DNA?
ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
What is the F factor in bacteria?
The donor bacterium carries a DNA sequence called the fertility factor, or F-factor. The F-factor allows the donor to produce a thin, tubelike structure called a pilus, which the donor uses to contact the recipient.
Are pyrimidines double ringed?
D. The pyrimidines, cytosine and thymine are smaller structures with a single ring, while the purines, adenine and guanine, are larger and have a two-ring structure. The purines, adenine and cytosine, are large with two rings, while the pyrimidines, thymine and uracil, are small with one ring.
Where is the code in DNA?
The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid? will be added next during protein synthesis. There are 20 different amino acids, which are the building blocks of proteins.
What are monomers of DNA called?
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
What F means in biology?
When displaying crossings between two parental organisms, the resulting offspring are referred to as F1. The F stands for “fili” meaning “sons” or “offspring”.
What is F factor biology?
The plasmid that allows a prokaryote to conjugate with and pass DNA into an F- cell. A bacterial episome whose presence confers donor ability (maleness).
