T F T F T T F F The major bonds in cellulose are a(1-4) bonds. Answer: During mRNA splicing, U2 binds to the 3' splice site. Eukaryotic ribosomes act to remodel chromatin or stabilize binding of the RNA polymerase. DNA sequences that prevent enhancers from acting on promoters located in adjacent domains are called boundaries.

________ -dominance is a melting or a blending of phenotypes

Can someone show me why this is correct? I will like to see the possible genotypes and phenotypes together that proves the answer.

This question is about a medical condition that is inherited as an autosomal dominant allele. In this condition the dominant allele is lethal when homozygous. Recall that autosomal genes are found on non-sex chromosomes.   Two parents who are thinking of having another child are trying to determine the likelihood of passing on this allele to their children. They consult you to find the answers to their questions. One of them has the condition and one does not. Their first child is unaffected. What is the probability that their second child is unaffected? Express your answer as a decimal to 2 decimal points, e.g. 0.81. If your answer is a whole number, e.g. 3, then leave it as 3.
