Ribonucleic Acids
In addition to mRNA, DNA codes for other forms of RNA, including ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), and small nuclear RNAs (snRNAs). rRNAs and tRNAs participate in protein assembly whereas snRNAs aid in a process called splicing -the process of editing of mRNA before it can be used as a template for protein synthesis.
any of the forms of a gene that can occupy the same locus
Methylation also plays an important role in genomic imprinting, which occurs when both maternal and paternal alleles are present but only one allele is expressed while the other remains inactive.
a specific sequence of three adjacent nucleotides on a strand of DNA or RNA that specifies the genetic code information for synthesizing a particular amino acid
Here the mRNA is translated into protein by decoding the mRNA sequence in blocks of three RNA bases, called codons, where each codon specifies a particular amino acid.
Determining the allelic condition used to be accomplished solely through the analysis of pedigrees, much the way Mendel carried out his experiments on peas.
