What does DNA look like?
Twisted ladder This structure is also known as a double helix.
The building blocks of protein are called?
amino acids Amino acids link together to form proteins.
What does tRNA stand for?
transfer RNA tRNA carries amino acids to the ribosome.
What does DNA stand for?
Deoxyribonucleic Acid DNA is the molecule that carries genetic information.
Who is given credit for publishing the shape of DNA?
Watson and Crick They proposed the double helix model of DNA.
The nitrogen base that pairs with Adenine in the DNA is?
Thymine This base is part of the complementary base pairing in DNA.
The small sections of DNA that carry codes that make up your traits are called?
Genes Genes are segments of DNA that code for proteins.
How many genes do humans have?
roughly 30,000 This number can vary slightly among individuals.
How many types of RNA are there?
3 The three types are mRNA, tRNA, and rRNA.
What does RNA stand for?
Ribonucleic Acid RNA plays a crucial role in coding, decoding, regulation, and expression of genes.
The nitrogen base that pairs with adenine in RNA is?
Uracil Uracil replaces Thymine found in DNA.
What does rRNA stand for?
ribosomal RNA rRNA makes up part of the ribosome.
Where do these nitrogen bases attach?
The sugar ‘Sides of the Ladder’ This refers to the structure of the DNA double helix.
A permanent change in the DNA is called?
Mutations Mutations can lead to changes in protein function.
The nitrogen base that pairs with Guanine in DNA is?
Cytosine This is part of the base pairing rules in DNA.
The nitrogen base that pairs with Cytosine in DNA is?
Guanine This is part of the complementary base pairing in DNA.
Where does RNA take the genetic code?
Ribosomes Ribosomes are the sites of protein synthesis.
DNA contains the ___ for all growth and function of the organism.
instructions These instructions are encoded in the sequence of nucleotides.
The codes that genes carry create a specific type of ___ that determines your traits.
proteins Proteins are essential for various functions in the body.
Part of a gene that consists of 1 sugar phosphate and 1 nitrogen base is called?
Nucleotides Nucleotides are the basic building blocks of DNA and RNA.
The part of the cell cycle where DNA is copied is called?
interphase Interphase is crucial for cell division.
When DNA untwists, unzips, and nucleotides fill in, this process is called?
DNA replication This is essential for cell division.
What molecules make up the sides (backbone) of DNA?
Sugar Phosphates The sugar-phosphate backbone provides structural support.
Is a molecule that helps take the code from the nucleus to the ribosomes?
RNA RNA serves as a messenger carrying instructions from DNA.
