Hey Moiz, thanks for putting together your questions, its super organized!
1) All DNA polymerases read 3'-->5' and synthesize 5' to 3'. Page 62 is a reiteration of that concept, that all nucleotide based processes go 5'-->3' except reading by DNA polymerase.
2) RNA transcription occurs 5'-->3'. The TATA box is located upstream to the code of interest (at the 5' end).
3) No; stop codons are unique to the translation of the RNA code to protein, while transcription stops are coded into the DNA code. The stop mechanism has more to do with the physical characteristics of the RNA that is generated that helps to separate polymerase from reading the DNA strand.
4) RNA translation occurs 5' to 3', so the codons are read 5' to 3'. This reading is in relation to the mRNA.
5) Translocation is the movement (new location) of the ribosome to the next codon, towards the 3' end.
6) Yeah you can say it like that; but remember that the tRNA code table will depend on the species you are looking at. Some species have different tRNA tables, so I can't guarantee on the exact number. Stop codons don't code for AA if that's what you are wondering.
7) Epigenetics don't change the sequence, but it changes the access to the sequence of DNA. So yes, it affects chromatin structure.
8) Genome = the set of chromosomes an organism has, Gene = one area of the genome that codes for something specifically.
9) Germ cells are halploid... can you tell me what page you saw this on? I'll have someone look at it. Thank you!
10) Meiosis I is still diploid. When meiosis II occurs, the cells will become haploid as no additional replication of genome will occur.
11) Meiosis I is complete in females by the time birth occurs. Meiosis II occurs when ovulation is occuring, and stops at Metaphase II unless fertilized.
12) I heard this question in one of the sessions, and the instructor said that its not important to know this detail, and that if you need to know it, it will be talked about in the passage. Centrioles are 9+2 is what's important to know.
Hope this all helped, happy studying!
Cheers,
Molly
