Modern Genetics Flashcards
what does is mean when a gene is gene linked
when they are close together on the chromosome
what does it mean when a gene is sex linked
traits that are influenced by genes are carried on the se chromosome
what does it mean when a gene is segregated
both alleles of a given gene are expressed equally in each offspring
which parent passes a sex linked trait to each offspring
mother passes the XX, father passes the XY
why is bacteria used in recombinant DNA
they are simple to control, duplicate quickly
why is recombinant DNA used
allows scientists to manipulate DNA fragments
what is used to cut dna with recombinant dna
restrictive enzymes
how do you calculate the amount of nitrogen base in dna
they will be equal to the number of nucleotides
]what is a mutation
a change in the sequence of nitrogen bases
how to recognize a mutation from a given DNA code
comparing the sequence to a normal gene
what is the difference between autosomal chromosomes and sex chromosomes
Autosomes are those chromosomes present in the same number in males and females, while sex chromosomes are those that are not
where do mutations occur?
in the somatic cell
where will the change go if it is in the gamete
into the offspring (if it isnt in the gamete it will stay there)
what is deletion
a loss of part or all of the code
what is insertion
when a segment of the code is repeated
