DNA Structure
This molecule's shape is defined as a double helix
What is DNA?
RNA and DNA can both be found in this organelle of the cell.
What is the nucleus?
This is the end product of protein synthesis
What is protein?
This is a molecule consisting of DNA tightly coiled around proteins
What is a chromosome?
Having a single copy of this kind of allele results in its trait being expressed.
What is dominant?
This base is found in DNA but not in RNA, which replaces it with uracil.
What is thymine?
This enzyme can unwind DNA molecules during the process of DNA Replication
What is the helicase?
This can leave the nucleus of the cell due to its small size, allowing proteins to be translated from it.
What is mRNA?
Humans have this many pairs of chromosomes, leading to 46 total
What is 23?
The genes of an organism, represented with two letters.
What is a genotype?
This RNA sequence is complementary to the DNA strand GCATTT
What is CGUAAA?
This enzyme is responsible for gluing together Okazaki fragments during DNA replication along the lagging strand
What is the ligase?
A copy of RNA is made in the nucleus in this process.
What is transcription?
These small segments of DNA on the chromosome code for proteins.
What are genes?
A variant of a gene for a particular trait
What is an allele?
These are the building blocks of DNA, consisting of a sugar, a phosphate, and a nitrogen base
What are nucleotides?
This kind of bond holds the base pairs DNA molecules together; RNA uses it during complementary base pairing.
What is a hydrogen bond?
This organelle helps to translate the RNA in the cytoplasm to the protein by matching the RNA code with amino acids
What is a ribosome?
If you have this miniature chromosome, you are a male; otherwise you are a female.
What is the "Y" chromosome?
If two parents who are heterozygous (Gg) for the dominant trait of green hair have offspring, these are the chances their offspring will have the recessive trait of purple hair.
What is 25%?
The strands of DNA are this, meaning they are different from each other but match with each other.
What is complementary?
This phrase is used to describe how DNA replication produces a DNA molecule with one original strand and one newly synthesized strand
What is semi-conservative?
These sequences of three base pairs correspond to amino acids carried by TRNA molecules in the cytoplasm of the cell
What is a codon?
Down syndrome results from having an additional copy of chromosome 21, which occurs due to problems in this process, the name for the production of gametes.
What is meiosis?
If two parents who are heterozygous (Gg) for the dominant trait of green hair have offspring, these are the chances their offspring will be heterozygous.
What is 50%?
