The fatal human illness called Huntington diseaseLinks to an external site. is caused by a dominant mutant allele. Calculate the probability that a couple will have a child with at least one copy of the recessive allele if the father is heterozygous and the mother is homozygous recessive. - ️️1 in 1 or 100% The mRNA of human insulin codes for 24 more amino acids than are present in the final insulin protein. What is a possible function of these additional amino acids? - ️️Direct th...

Griffith Experiment observed change in streptococcus pneumoniae from bacteria without capsules (avirulent R rough colonies) to bacteria that had capsules (virulent S smooth colonies); result: heat-killed virulent bacteria could transform avirulent bacteria into virulent bacteria (prove that DNA is a genetic element) Meselson and Stahl Experiment DNA replicaition was semiconservative Avery Experiment genes are made up of DNA what are the base-pairing rules? T and A, C and G how many hyd...

Everything is just like the original experiment (the bacteria is grownin many generations in 15N and then switch to light 14N) and DNA replication is semi-conservative and the culture is grown in light media for two generations. - Answer-tube C In a cell grown for many generations in the presence of fluorescent nucleotide, and then moved to grow in a medium containing only normal, nonfluorescent nucleotides for exactly one round of DNA replication, which pattern of fluorescence shown in the...

People to Know - AP Biology Exam Questions and Answers Gregor Mendel Monk who grew up in Austria, experimented with garden peas in 1857 to study inheritance, documented "particulate mechanism", came up with laws of independent assortment and segregation. Thomas Hunt Morgan Came up with first solid evidence associating a specific gene with a specific chromosome by working with various varieties of Drosophila; invented notation for symbolizing alleles; discovered sex-linked trait of whit...
