Minor nitpick but there is no interphase after meiosis I. It pretty much goes straight to meiosis II.billyhoho wrote:Meiosis also has 2 stages, like (I'm going to use abbreviations because I'm lazy) P1 M1 A1 T1 -(another space here for G1 and stuff again)- P2 M2 A2 T2. Also, meiosis 2 (the second stage) is the same (practically) as mitosis and meiosis DOES NOT occur in gametes. It CREATES gametes. It OCCURS in germ cells.Whoppers wrote:Mitosis occurs in somatic (or body) cells while meiosis occurs in sex cells (or "gametes") only.scimystery wrote:Hi, I did Heredity last year but I missed a lot of topics...luckily there wasn't much on them and I had a lot on my paper, but I still can't tell the difference between mitosis and meiosis....Ehehe... Help?

Re: Heredity B/Designer Genes C
any one know of any really good websites for learning sanger DNA sequencing analysis? i need a refresher on how to analyze those annoying electrophoresis gels.

Re: Heredity B/Designer Genes C
Wikipedia has a great resource for Sanger sequencing, other than that, davidson.edu has a pretty good intro on Sanger: http://www.bio.davidson.edu/courses/mol ... d_page.htm

Re: Heredity B/Designer Genes C
should we know about modern genetics analysis for this event?

Re: Heredity B/Designer Genes C
Well it doesn't specifically say in the rules, but I've seen questions here and there about it. I wouldn't worry too much about it, the main topics on the rules are what you should mainly focus on.

Re: Heredity B/Designer Genes C
I'm having trouble understanding the DNA replication process. What role does the rRNA play in it? Additionally, what is the polymerase?

Re: Heredity B/Designer Genes C
rRNA has no part as far as I know in DNA replication. It stands for ribosomal RNA, and is used in translation.
Polymerase is the actual enzyme that attaches the new bases to the template strands.

Re: Heredity B/Designer Genes C
On my regionals this year, there was one question me and my partner couldn't answer. What is R phase of the cell life cycle?
