In molecular biology, restriction fragment length polymorphism, orRFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a differencebetween samples of homologous DNAmolecules from differing locations ofrestriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated. InRFLP analysis, the DNA sample is broken into pieces and (digested) byrestriction enzymes and the resultingrestriction fragments are separated according to their lengths by gel electrophoresis. Although now largely obsolete due to the rise of inexpensive DNA sequencing technologies, RFLP analysis was the first DNA profilingtechnique inexpensive enough to see widespread application. RFLP analysis was an important tool in genome mapping, localization of genes forgenetic disorders, determination of riskfor disease, and paternity testing.

For him they were just discrete physical units of inheritance. Johanson coined the term "gene" and people started calling them genes. Today for us these factors are parts of DNA, the base sequences that carry the biological information to determine a trait. Mendel factors are alleles of genes.
B: things made of a single atom
Answer:
A, B, E
Explanation:
rRNA is ribosomal RNA
tRNA is transfer/transport RNA, and it brings amino acids to the ribosomes so they can make proteins.
mRNA is messenger RNA

Answer:
Explanation:Aside from the structures mentioned above, bacteria have a specialized region that allows them to survive. Instead of a central nucleus, bacteria have the region called nucleoid (literally means “nucleus-like“) that contains the suspended genetic material.. Unlike eukaryotic genetic material, the genophore (prokaryotic DNA), is a double stranded circular one.
