Genes/ Chromosomes
Genes are found on sections of
DNA
Nucleotides contain what 3 parts
sugar, phosphate, and base
In which phase of the cell cycle does the cell make a copy of it's DNA?
Interphase
where does protein synthesis occur?
ribosomes
What are a few purposes of Mitosis?
Replace dead and dying cells
heal cuts and injuries
growth
23
What are the four possible bases for a nucleotide?
Adenine, Thymine, Guanine, and Cytosine
What occurs during Mitosis?
the cell divides its chromosomes
What molecule carries the genetic code from DNA in the nucleus to the ribosomes?
mRNA
The new cell that is formed from the union of two gametes is called a
zygote
Cells with 2 of each chromosome are called
Diploid
In RNA which base from DNA is replaced? What is it replaced with?
Thymine is replaced by Uracil
Asexual
Sexual
amino acid
During cell division what part of the cell is separated into two cells but does not have to be separated equally between both cells?
cytoplasm
What is the term for combining egg and sperm?
fertilization
describe the difference between haploid and diploid cells
Haploid are cells with half the number of chromosomes in a full cell, they only have one copy of every chromosome. Diploid cells have a two of each chromosome which are the regular body cells.
Regeneration and budding are types of ________ replication?
asexual
Which of the following never contains the code for a sequence of amino acids needed to manufacture a protein?
tRNA
similarity- both are reproduction, both result in offspring
difference- asexual has identical offspring sexual does not, asexual is one parent and sexual is two, and sexual is done by meiosis and has two divisions.
When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called
Sister chromatids
scientist who came up with the structure of DNA
watson and crick
what are the phases of Mitosis and what occurs in each phase
Interphase- DNA duplicates
prophase- sister chromatids form
metaphase- line up in middle
anaphase- pull apart
telophase- start to form new membranes
cytokinesis- division and end with two cells
the process of making mRNA from DNA
putting amino acids together in a specific sequence
Transcription
protein synthesis
How is protein synthesis evidence for a creator?
it is a very complex process where everything must be in the right place at the exact time for it to work correctly.
