4. Which statement about chromosomes is true?
C. Chromosomes contain DNA
5. What modification affects the characteristics expressed by an organism while leaving its DNA sequence unchanged?
B. Epigenetic Change I just wanted you to know that you are the only reason I’m passing biology. i love you guys <3 100%! However, the answer to number one is "AGC TTT CG" not "AGA TTT CG". M. is right I got 100% Thanks dude! Thanks. That’s 100% correct Thank you sir! 100% For number one, it is AGC TTT CG and not AGA TTT CG. But it’s still correct. Thanks! they changed it now for question 5 If a cell has two copies of each chromosome, what type of cell is it? the answer is: A diploid M. cell is 100% correct for Honors Biology Genetic Variation From Errors! Thanks dude ! M. still valid Still valid on 05/01/22 all correct for HONORS BIO!!! some of you are complaining that it’s incorrect but are probably in the standard bio mr. you are 100% right ty sm ♡ If you do “Quick Genetic Error Check” I got 100%. the answers can be reversed, but GOOD LUCK!! I got a 100% thank you bruh I only got 1 and 4 well all wrong
