biol+4+glossary+aos1a

The creation and use of the glossary will be slightly different for this unit. I would like relevant terms to be added to the table. You can decide on how to organise the table and what labels to use. Under the table I will be asking each of you as part of your H/W to post sentences that combine two words from the table into a biologically accurate statement that shows understanding of the words. One of the struggles for many of you during unit 3 was trying to cope with terminology right up until the exam. I am hoping this activity will assist you all in this area.

making links glossary aos1b  Back to activities page Back to standard glossary aos1  A most impressive start (thanks to the one person who has heeded the advice). the next step is to sort the terminology into groups (this is where the headings come in), if you need to add more rows, click on a box and you will get a pull down menu.
 * A new page for aos1 has been created. Click the link below. **

(1) DNA polymerase is an enzyme which allows another nucleotides to be added to a DNA strand which are complemetary to the **template strand.** (2) During synthesis of the **lagging strand**, the DNA is composed in fragments known as Okasaki Fragments which are eventually joined together by **DNA ligase**. (3) Semi-conservative replication occurs when DNA is newly synthesized and contains one parent strand and one new strand after the parent DNA has been seperated by the enzyme **helicase.** (4) Diploids are two pairs of chromosomes (ie 46) whereas **haploid ** cells contain only one set of chromosomes (ie 23) (5) Mitosis, a form of asexual reproduction, is primarly used for growth and repair in multicellular organisms, and results in a parents cell producing two identical daughter daughter cells (6) Meiosis occurs in specialised cells called **germ cells **, and is a process which produces sex cells through sexual reproduction (7) Helicase is an enzyme which unzips a DNA molecule during **DNA replication** (8) A pair of **<span style="background-color: rgb(254,244,52);">chromosomes ** that contain the same genes at the same location are known as a <span style="background-color: rgb(254,244,52);">Homologous Pair (9) Identical copies of an original chromosome (ie a pair) are known as <span style="background-color: rgb(254,244,52);">Sister Chomatids. Sister chromatids also have similar pairs which are referred to as **homologous** due ot similar size, shape, **centromere** positioning. (10) The site where chromosomes are attached to spindle fibres is known as the <span style="background-color: rgb(254,244,52);">Centromere. This occurs during both **mitosis** and **meiosis**. It really attaches at the **kinetochore** - a specialised protein structure. (11) A specialised <span style="background-color: rgb(254,244,52);">diploid parent cell called a <span style="background-color: rgb(254,244,52);">germ cell, undergoes Meiosis to produce 4 <span style="background-color: rgb(254,244,52);">haploid daughter cells, called <span style="background-color: rgb(254,244,52);">gametes (sex cells). (12) In <span style="background-color: rgb(254,244,52);">DNA Replication, <span style="background-color: rgb(254,244,52);">DNA helicase unwinds the double-stranded DNA molecule, allowing <span style="background-color: rgb(254,244,52);">DNA polymerase to synthesise a daughter strand from each <span style="background-color: rgb(254,244,52);">template strand. (13) A <span style="background-color: rgb(255,255,0);">gene mutation is a small, localised change in the structure of a DNA molecule (either of a single nucleotide or a triplet) caused by a **<span style="background-color: rgb(254,244,52);">mutagen ** which can result in an altered sequence of **<span style="background-color: rgb(254,244,52);">amino acids ** and the disruption of a desired protein's biological function.

//<span style="color: rgb(19,22,241);">the sentences are great and the highlighting of the terms is a really good idea. Sentence 1-10 and 13 need to have another relevant term highlighted. VM //

I made some corrections, so they should all be good now except for no. 5 - i couldn't think of anything.

//<span style="color: rgb(19,22,241);">What about adding "and results in a <span style="background-color: rgb(254,244,52);">parent cell producing two identical <span style="background-color: rgb(254,244,52);">daugther cells." VM //

could you give an example please voj? <span style="color: rgb(19,22,241);">//An example of what? Be specific. If you mean a sentence, then you need to first put some terms in the table, for me to use. If you mean examples of terminology, then I suggest you read the notes because there are plenty of words (new ones too) that relate to what we have done. VM// no i dont think i understand how the table works. each box has a new term AND its definition..? maybe you can you give an example of a heading, thats probably what im looking for.! thanks //<span style="color: rgb(19,22,241);">Each box only contains a term, not a definition. the sentence constructions are designed to show an understanding of what terms mean and more importantly, how they relate to other terms. each of you can keep your own standard glossary if you wish or I will put up another page for that. this is different. the heading are up to you, they don't need to be filled in straight away. once terms start to be added you might group them into certain areas and this is where the heading comes in. one example might be the name of a process such as DNA replication but I want you to come up with the groupings, you to do the thinking. VM //

If you don't mind, it would be great if you could create a new page with the old structure for the glossary - i promise ill contribute to this one too.//<span style="color: rgb(19,22,241);"> done, I have called it the standard glossary VM //

Ok, i've attempted organising the table; theres a few i was unsure about, so it might need some editing! LB // That's OK LB, the others should now analyse what you have done. You can find my comment at the top if you haven't noticed it. VM //
