DNA and RNA
Heredity/ Traits
Recessive traits can be carried in a person's genes without appearing in that person. For example, a dark-haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
Homozygous and Heterozygous
DNA and mRNA strand
This enzyme, which naturally occurs in retroviruses, operates in a single strand of mRNA generating its complementary DNA based on the pairing of RNA base pairs (A, U, G, and C) to their DNA complements (T, A, C, and G). X-linked diseases are single gene disorders that reflect the presence of defective genes on the X chromosome. This chromosome is present as two copies in females but only as one copy in males. DNA replication is the process of producing two identical replicas from one original DNA molecule. Protein synthesis is one of the most fundamental biological processes by which individual cells build their specific protein. Transcription, the information encoded in the DNA is copied to a mRNA molecule as one strand of the DNA double helix is used as a template. In translation, mRNA along with transfer RNA (tRNA) and ribosomes work together to produce proteins.
