Signal Sequences: 1)A signal sequence is made of: a. Nucleotides b. Amino acids c. Lipids d. Carbohydrates 2)All protein synthesis starts on ribosomes that are located in the . 3)If a molecule lacks a signal sequence it will end up in the 4)Proteins with a nuclear localization sequence (NLS) are generated on ribosomes located in the . 5)Proteins with a mitochondrial signal sequence are generated in ribosomes located in the .

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
