questions idk

Question 1

suggest why a ratio is not obtained in the offspring of a genetic cross

Answer 1

• sample size is too small/ too few crosses
• fewer of one than predicted, larger of another than expected
• some may not survive e.g HH or GG
• some more likely to die, some less likely to die
• random/ role of chance

Question 2

describe the differences between the process of transcription and translation

Answer 2

• transcription occurs in the nucleus
• transcription uses DNA to make RNA
• DNA unzips/ one strand is copied
• transcription makes/produces mRNA
• translation takes place at ribosomes in cytoplasm
• translation involves mRNA and tRNA
• anticodons bind to codons
  -translation produces amino acid chain/protein/polypeptide
