Mitochondria and chloroplasts resemble bacteria in that they correct answers have their own DNA, have their own ribosomes, reproduce by simple division into two. Which of...

Lesson Plan: Title Transcription Part II: What happens to the initial (premRNA) transcript made by RNA pol II? Objectives  Explain how the transcript generated by RNA polymerase II (the pre-mRNA) is processed to become mature mRNA, using the sequence signals identified in Module 2.  Use the genome browser to analyze the relationships among: 1. pre-mRNA 2. 5’ capping 3. 3’ polyadenylation 4. splicing 5. mRNA Pre-requisites  Modules 1 and 2  Define pre-mRNA as the RNA ...

The DNA coding for a particular protein consists of 600 base pairs. How many amino acids are in the protein encoded by this gene? - Answer- 200 amino acids The process shown in the diagram is oogenesis in giraffes. Egg cells of giraffes have 15 chromosomes. How many chromosomes and chromatids would be found in the cell indicated with an arrow? - Answer- 15 chromosomes, 30 chromatids The DNA of a cell is replicated during what phase of the mitotic cell cycle? - Answer- S The genome of th...

Lecture 6: Vocab: ● Autosome: ○ Any chromosome not considered as a sex chromosome, or is not involved in sex determination. ○ It occurs in pairs in somatic cells and singly in sex cells (gametes) ● Bivalent: ○ a pair of homologous chromosomes. ● Drosophila melanogaster: ○ a species of fruit Fly much used in genetics because of the large size of its chromosomes. ● Epistasis (gene x gene interaction): ○ refers to genetic interactions in which one gene modifies the eff...

define one genetic map unit ~ the physical distance between two genes that results in a 1% frequency of recombination In birds, sex is determined by ZW chromosome inheritance. Males are ZZ and females are ZW. Within pigeon populations there is a recessive, Z-linked allele that is lethal in embryos. What is the expected sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a wildtype female? ~ 2:1 male to female A recessive allele on the X c...
