How does DNA Replication happen? Step 1 : An called helicase, the DNA molecule which the bonds that hold the base pairs together. When the bonds break and the separate, the for the new DNA molecule is .

Step 2 : Free- , one by one, with the bases on the template strands. DNA help the bases their correct , As with Ts and Cs and Gs, and them together.

END RESULT : new DNA molecules, each made up of one strand of the original DNA molecule along with a newly formed matching strand.

DNA replication is called because each DNA molecule is made of one old strand and one complimentary new strand. Each new molecule is identical to the original molecule of DNA. pls helpmasamthths31​

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?
