Building Blocks of Genetics | Phases | Mendelian Genetics | DNA | Protein Synthesis |
---|---|---|---|---|
What is a chromosome
Each very long chromatin fiber twists and folds to form this.
|
What is Metaphase I (Meiosis only)
Homologous pairs line up in the middle of the cell.
|
What is heredity
This is the transmission of traits from one generation to the next.
|
What is deoxyribose
The D in DNA stands for this part of the molecule.
|
What are proteins
_________ perform the majority of cellular functions and control physical traits.
|
What is a gene
A small segment of the chromosome, this contains the information needed to build one or more strands of protein.
|
What is Anaphase (Mitosis) and Anaphase II (Meiosis)?
Sister chromatids are pulled apart by the spindle fibers.
|
What is a trait
Each possible variation of a character, such as brown eyes.
|
What is semi-conservative
New DNA molecules are made up of one of the original parental strands plus a new half, making them __________.
|
What is mRNA
During transcription, DNA is transcribed into a single strand of _____________ before leaving the nucleus.
|
What are sister chromatids
Pairs of duplicated chromosomes are called what.
|
What is Telophase II (Meiosis)?
Four haploid cells start to form, with the nuclei reforming.
|
What are alleles
Alternate forms of a particular gene are called _______.
|
What are deoxyribose (sugar), phosphate, and a base
A DNA nucleotide is made up of these three general parts.
|
What is tRNA.
This type of molecule carries amino acids to the ribosome during translation.
|
What are homologous pairs
Most of the cells in your body are diploid, meaning they have two copies of each chromosome. These two copies together are called ________________.
|
What is Prophase (Mitosis), Prophase I (Meiosis I), and Prophase II (Meiosis)?
Chromosomes condense, nucleus starts to dissolve.
|
What is Bb
If an organism was heterozygous for eye color (B) what would be their genotype?
|
What is TACAG
Given a strand of DNA with the bases ATGTC, provide the complementary strand.
|
What is 3
Codons within the mRNA are made up of this many nucleotides.
|
What is crossing over
Chromosomes can “swap” genetic material, creating new, unique combinations. The name of this process is ___________.
|
What is cytokinesis
Cell plate divides the cell into two.
|
What are brown eyes
If an organism was heterozygous for eye color (B), with brown being dominant and blue being recessive, what would be their phenotype?
|
What is helicase
During DNA replication, this enzyme helps "unzip" the two strands of DNA.
|
What is a polypeptide
This is the result of translation, which can be described as a strand of amino acids that acts as a pre cursor to a final protein.
