Question

question 1 (1 point)
what is genomic mapping?
a) a process used to separate fragments based on charge and size.
b) the technique of quickly making copies of dna using enzymes and a cyclic
fluctuation in temperature
c) a process in which the size and order of dna segments is determined.
d) a technique in which dna samples are cut by restriction enzymes, and the
resulting fragments are separated via electrophoresis creating a pattern of
bands.

Explanation:

Genomic mapping involves techniques to analyze DNA. Option a) describes gel electrophoresis which is used in genomic mapping to separate DNA fragments based on charge (DNA is negatively - charged) and size (smaller fragments move faster through the gel matrix). Option b) is PCR (Polymerase Chain Reaction) which is for making copies of DNA. Option c) is related to techniques like gel electrophoresis for determining DNA segment size but the description is more about the general concept of size - based analysis rather than the specific process in genomic mapping. Option d) is also about gel electrophoresis but the description is more about the result (pattern of bands) rather than the process as a part of genomic mapping.

Answer:

a) A process used to separate fragments based on charge and size.
