AQA A-level Biology paper 1 Rated A large molecules often contain carbon. why? Ans- they can readily form bonds with other carbon atoms. this forms a 'backbone'. other atoms can then attach. describe benedicts test for reducing sugars Ans- add equal volumes of the sugar sample and benedicts reagent. heat the mixture in a water bath for 5 minutes. brick red precipitate will form. what is a reducing sugar? Ans- a sugar that can reduce (give electrons to) another chemical. describe the ...

1 — Structure of DNA and Chromosomes Understand the structure of DNA. If one strand of a DNA double helix has bases "ATCCGC," what bases are on the other strand of the helix? • a.) GCCGAT • b.) GCTTAT • c.) TAGGCG • d.) TTCCGA 2 — Mitosis Identify various components of mitosis In which phase of mitosis do the chromosomes line up and become attached to spindle fibers? • a.) Prophase • b.) Telophase • c.) Metaphase • d.) Anaphase 3 — Meiosis and Genetic Va...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands Correct Answer- true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? Correct Answer- RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as...

Hemophilia Pedigree - Father has hemophilia, mother does not. What is the outcome for their kids? - ANS His daughters would be carriers. This is x-link recessive. Autosomal: Dominant: - ANS Autosomal: males and females equally affected. Dominant: non-carrier parents Polymerase chain reaction (PCR) ANS The process of copying DNA in the lab. Uses Template DNA, Nucleotides (dNTPS), DNA polymerase, and DNA primers. 3 Steps of PCR ANS 1. Denaturation: DNA is heated to 95C to separate it. 2....
