DNA

Question 1

DNA

Answer 1

: Deoxyribonucleic acid, a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms

Question 2

RNA

Answer 2

Ribonucleic acid, a molecule that is transcribed from DNA and is involved in protein synthesis

Question 3

Chromosomes

Answer 3

Thread-like structures located inside the nucleus of animal and plant cells, consisting of DNA and protein; they are the carriers of genes

Question 4

Genes

Answer 4

Small sections of DNA that are the basic physical and functional units of heredity, containing the instructions for making proteins and determining traits

Question 5

Double Helix

Answer 5

The structure of DNA, resembling a twisted ladder, formed by two strands of nucleotides held together by hydrogen bonds

Question 6

Allele

Answer 6

One of two or more versions of a gene that are found at the same place on a chromosome and that control the same characteristic

Question 7

Nucleotide

Answer 7

The basic building block of nucleic acids, such as DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base

Question 8

Protein

Answer 8

Large, complex molecules that play many critical roles in the body, including providing structure, regulating processes, and serving as enzymes

Question 9

Genetic information

Answer 9

Information about an individual’s genetic tests

Question 10

Deoxyribose

Answer 10

A simple sugar that forms the backbone of DNA molecules

Question 11

DNA Strands

Answer 11

Long chains of deoxyribonucleic acid that carry genetic information in the form of a code made up of four nitrogenous bases: adenine, thymine, guanine, and cytosine

Question 12

Hydrogen Bonds

Answer 12

Chemical bonds that connect the two strands of DNA, holding them together in a double helix structure

Question 13

Ribosome

Answer 13

A large complex of RNA and protein that plays a central role in protein synthesis

Question 14

Cytoplsm

Answer 14

The jelly-like substance found inside a cell, excluding the nucleus and other membrane-bound organelles

Question 15

nucleous

Answer 15

A membrane-bound organelle in eukaryotic cells that contains most of the cell’s genetic material, including DNA

Question 16

Chromatin

Answer 16

A complex of DNA and proteins, mainly histones, that forms the chromosomes in the nucleus of a cell

Question 17

Answer 17

The process by which a cell copies its DNA to create new DNA molecules for cell division or repair

Question 17

Histone

Answer 17

A type of protein that plays a structural role in organizing DNA in the nucleus of a cell

Question 18

Nitrogen Bases

Answer 18

Chemical compounds that form the building blocks of DNA and RNA, including adenine, thymine, guanine, and cytosine

Question 19
