module 2

• the endonuclease is where DNA sequence errors can be repaired
• Intron excision is a segment of a gene that is transcribed, but cleared out of the mRNA sequence during RNA process of transcription
• Polymerase is an enzyme that processes long chains of nucleic acid polymers
• Invitro is a latin 'within the glass' word used in the lab to describe experiments performed
• A helicase is an enzyme that unwinds DNA during DNA replicaiton
• Segments of a gene sequence that are translated into amino acids are called exons
• Hereditary is the transmission of traits from one generation to the next
• translation is the process which an amino acid polymer is synthesised using mRNA template
• deoxyribose is the sugar component of nucleotides
• transcription factors are regulatory proteins that bind to DNA and instigate transcription of a gene
• dihybrid test cross is used to determine whether the 2 genes are closely linked on the same chromosome
• the 4 daughter cells created during meiosis are called gametes
• dna replication is semi-conservative
• Ligase is the DNA molecule replication that creates phosphodiester bonds between newly synthesised fragments
• Diploid (2n) are two sets of chromosomes
• Exonuclease is how DNA sequence errors can be repaired during DNA replication
• In eukaryotic DNA replication, there are multiple origins of replication, each replication forming a bubble
