Define Mendel's law of independent assortment. Group of answer choices The expression of one gene has no effect on the expression of another gene. There are two versions of each trait, a dominant and a recessive; the one you get is random. Segregation of homologous chromosomes is random. The inheritance of one character has no effect on the inheritance of another character.

The inheritance of one character has no effect on the inheritance of another character.

Explanation:

Gregor Mendel's law of independent assortment described the inheritance of genes as being an independent events. That is, genes coding for separate characters are inherited independently of one another.

As such, hair colour, eye colour and colour of the skin in a particular organism are coded for by separate alleles and their inheritance is an independent event. They do not interfere with one another.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
