Noncoding DNA has no biological purpose. True  False

1- The following Wild Type DNA codes for color in a lizard living in the Namib Desert (tan sand) a skin colorof reddish brown. This lizard is preyed upon by hawks flying above.Wild Type (Normal) DNADNA Template Strand: TAC-TTC-AAA-CCG-ATTDNA (silent strand): ATG-AAG-TTT-GGC-TAA For number 7, compare this change to the wild type in number 1. Remember that the originalpigment is a different color.7. Let us assume that the following protein (Met-Lys-Phe-Ser) changes the pigment deposited inthe lizard skin to a tan color. Would this be detrimental? Would this be beneficial? Explaineither answer.

4.) During DNA replication, the two strands of DNA are pried apart and then serve as templates for synthesis of new strands. However, there are some big differences in how the two strands are copied. Why is this so? Please describe in 4-5 sentences of your own words how replication proceeds on the two strands. 5.) During meiosis, when crossing-over occurs between two homologous chromosomes, it does not happen at a single point, but rather two points with a stretch of DNA in between. What are the two junction points called? b. What is the region between the two points called and what is different about this region compared to how double-stranded DNA usually is? c. If the region described in b.) is located within a gene and the two homologues have different alleles of this gene, what might happen that is a direct violation of Mendel's first law? (Describe the process with 2-3 sentences of detail.) a.

97. A plant having both male and female sex organs on different plants is referred to as: O hermaphrodite O gymnosperm O dioecious O monoecious O embryophyte

3) Why are single strand binding proteins (ssb proteins) needed in DNA replication? (note that you need to explain WHY ssb proteins are important, not just what they do)

1. please fill in the blanks

Please send me the question in 20 minutes it's very urgent plz

True or False: 1. There is a reduction in the length of the DNA after every round of replication. 2. When transcribing, growing transcripts always run towards the 5’end of the template strand.

7. Discuss the modes of actions by which the following three compounds disrupt DNA- associated processes. H,CO. „NHSO,CH; HN HN H,N° но Compound A Compound B Compound C

#3 under Process: The DNA polymerase bonds the new nucleotides together to form the new strand which is bonded to one side of the original strand.   True   False
