Select all that apply. a. allow the labeled cDNA copies of mRNA to hybridize to the DNA on the microarray. b. collect all the DNA in a nucleus of a cell. c. collect all the mRNA in a nucleus of a cell.
3 dni temu · Epigenetics. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi- ( ἐπι- "over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic ...
2 dni temu · Mapping refers to the process of determining the relative locations of landmarks or markers (such as genes, variants and other DNA sequences of interest) within a chromosome or genome.
3 dni temu · Gene mapping refers to the process of determining the location of genes on chromosomes. Today, the most efficient approach for gene mapping involves sequencing a genome and then using computer programs to analyze the sequence to identify the location of genes.
4 dni temu · A physical map, as related to genomics, is a graphical representation of physical locations of landmarks or markers (such as genes, variants and other DNA sequences of interest) within a chromosome or genome. A complete genome sequence is one type of physical map.
1 dzień temu · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
