If the template strand of DNA is of the sequence 5’-AGATCG-3’, what sequence will DNA polymerase synthesise?

The image above is missing its labels, all of which are provided below. Which of the labels should you place in the position number 4?

Which of the following options are the main functions of the S/G2 cyclin/ CDK complex? 

1. To ensure that the components required for DNA synthesis are available

2. To confirm that only one copy of the DNA has been synthesised

3. To confirm that newly synthesised DNA fragments are not damaged

4. To repair major breaks in the template DNA

You apply a drug to a cell that binds to double stranded DNA and prevents it from coiling into a tight condensed arrangement. Which stage of mitosis will this drug first affect?

In the above image, which of the numbered circles indicate the 5’ end of the nucleotide?

Suppose a plant has two alleles for colour, green is dominant and yellow is recessive. If we cross a heterozygous plant with a yellow homozygous plant, what is the expected ratio of green:yellow plants in the F1 progeny?

During meiosis, crossing over occurs between homologous chromosomes. The recombinant chromosome will most likely contain the same alleles as the non-recombinant chromosome if the genes are:

In cows, heterozygotes are roan in colour, while homozygotes are either red or white. When crossing a roan and white cow, what proportion of the offspring will be roan in colour?
