DNA & RNA

Match the base pairs. Adenine Thymine Guanine Cytosine Uracil adenine The process of a copying a gene's DNA sequence into a sequence of RNA is called transcription translation transmutation replication DNA contains which bases? Adenine, guanine, thymine, uracil Thymine, guanine, cytosine, uracil Cytosine, thymine, guanine, adenine Adenine, guanine, uracil, cytosine A geneticist isolates a gene for a specific trait under study. She also isolates the corresponding mRNA. Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA? No, the mRNA was partially degraded after it was transcribed. No, the final mRNA contains only exons, the introns were removed. Yes, the mRNA should contain more bases than the DNA sequence, because stop codons are added to the gene sequence. Yes, mRNA is made from a DNA template and should be the same length as the gene sequence. DNA is copied outside the nucleus. true false Drag the terms to show which process they are involved in. Translation mRNA leaves nucleus ribosomes tRNA brings amino acids rRNA read the mRNA message Transcription intron exon nucleus DNA copied promoters begin mRNA produced
