What is DNA non abbreviated name?
How was DNA sides of the "spiralling ladder" composed according to Francis Crick and James Watson (who first discoverd DNA)?
by alternating deoxyribose sugar and phosphate molecules and the rung made of two of four nitrogen bases
What is DNA actually formed of after Watson and Cricks' studies?
a large polymer, composed of smaller monomeric units known as nucleotide.
What is a nucleotide consist of?
a sugar, a phosphate, and either a purine-adenine or guanine or pyramidine-thymine or cytosine.
What does dehydration synthesis do to the nucleotides formed in DNA?
the nucleotides link together to form strands that are anti-parallel.
What are these nucleotide strands in DNA after being formed in dehydration synthesis connected by?
2 hydrogen bonds between adenine and thymine or by 3 hydrogen bonds between guanine and cytosine
What is the enzyme that adds complementary nucleotides to each separated strand in a section of DNA called?
DNA polymerase III
What is ribonucleic acid and how is it produced?
- by using the template message of DNA.
What can be known as the sense strand?
What does RNA polymerse connect itself too?
the sense strand.
What is the finished product of RNA transcription? What can this product become after being modified by enzymes?
- a single stranded RNA molecule
- transfer RNA; messenger RNA;or ribosomal RNA
What is a small RNA molecule, consisting of a strand of nucleotides folded into a clover-leaf shape, that picks up an unattached amino acid within the cell cytoplasm and conveys it to the ribosome for protein synthesis?
What is a single-stranded molecule of RNA that is synthesized in the nucleus from a DNA template and then enters the cytoplasm, where its genetic code specifies the amino acid sequence for protein synthesis?
What is a type of RNA, distinguished by its length and abundance, functioning in protein synthesis as a component of ribosomes?
What is the processby which RNA codes for the assemblyof protein known as?
How many types of RNA involved with translation?
what is large and small that are composed of protein and ribosomal RNA? how many?
The protein synthesis begins with the attachment of the small ribosomal subunit to a specific area of a messenger RNA, this specific area consists of what? and what is the RNA code to it?
- initian codon
- three nucleotides that have the nitrogen bases adenine, uracil, and guanine in a 5 to 3 direction.
What is the genetiic code that is a triple nucleotide within messenger RNA that signals the termination of translation?
