17 flashcards · Biology · by Serenity Underwood
DNA
deoxyribonucleic acid >> two strands, double-helix >> adenine and thymine; cytosine and guanine >> deoxyribose (sugar) >> canNOT leave the nucleus >> holds genetic information >> controls cell's activity
tRNA
transfer RNA >> brings amino acids to the ribosome to make desired protein
rRNA
ribosomal RNA >> makes ribosomes
genetic code
a chart that is used to find out what the amino acid mRNA is coding for >> follows the first letter to the third letter within the circle and rings >>> get your condon from mRNA >>> go in order to find the amino acid
RNA
ribonucleic acid >> one single strand >> three types of RNA >>> mRNA >>> rRNA >>> tRNA >> adenine and uracil; cytosine and guanine >> ribose (sugar) >> can leave the nucleus >> uses the DNA instructions to make proteins
protein
enzymes >> made of amino acids (monomers) >> vital for ALL life
amino acids
the monomers of protein
mRNA
messenger RNA >> creates instructions for how to make a specific protein
codon
the code from mRNA used in the genetic code to find the amino acid
anti-codon
pairs with codons
protein synthesis
to make proteins/enzymes >> two parts >>> transcription (first part) >>> translation (second part)
transcription
the first part in protein synthesis >> turns DNA to RNA >> uses DNA to get instruction for one protein
translation
the second part in protein synthesis >> turns mRNA (codon) to protein >> decodes mRNA into a sequence of amino acids (proteins)
RNA polymerase
an enzyme that helps with transcription >> adds RNA bases to make an mRNA strand >> uses part of DNA to know what bases are needed
nucleus
the "brain" or "control center" >> only eukaryotic cells >> eukaryotic cells have RNA floating within the capsule >> holds our genetic material >> controls activity within the cell
ribosome
makes proteins using protein synthesis >> occurs in both prokaryotic and eukaryotic cells
genetic code (cont.)
>> 20 amino acids >> ALL living things use the same genetic code >> codon are codes for amino acids >>> sets of three bases on mRNA >> most amino acids have more than one codon
