Question

A cell has 3 homologous pairs of chromosomes (6 chromosomes total). This cell undergoes meiosis. How many different gametes can form? O 32 08 04 16 none of these

Answer 1

ANSWER:

QUESTION 1

CORRECT ANSWER= 8 Gametes

A gamete for this organism will have three chromosomes. Each chromosome is one of two possibilities. Thus, there will be 2 x2 x 2 = 8 gametes or (2)3 = 8).

QUESTION 2

correct answer = 3`UUCUUGGG 5`

3`UUCUUGGG 5` RNA sequence is complementary to 5`AAGACCC 3` DNA sequence. because in RNA a Thymine is replaced by uracil.

wrong options

3`TTCTTGGG 5` is a DNA sequence because in RNA a Thymine is replaced by uracil. and is complenatary to 5`AAGACCC 3` ( DNA sequence.)

5`UUCUUGGG 3` is not correct answer because  the complementary strand will read from left to right in the 3′ to 5′direction and there must be 3`opposite to 5` and vice-versa (not 5`opposite to 5` and vice versa)`
