Answer:
"Necessities for Sexual Reproduction: * 2 versions of individual – male version & female version * Each version must produce a gamete – egg or sperm cell *The male version “gives” his gamete to the female version * The female version grows a new individual
Explanation:
Color Blindness is an X-linked trait. This explains why males are much more likely to have it than females. Offspring inherit Color Blindness from their mother, because the father only contributes the Y chromosome. A female can only have the disorder if her father has it and her mother either has it or is a carrier
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
Length of time candle burns is the correct answer.
<h2>Answer:</h2>
Chromosomes are structures present in the nucleus of the every organism's cell and it is the DNA packed with histones proteins.
Explanation:
DNA deoxyribo nucleic acid is the nucleotide sequence which is the blue print of the structural and functional characteristics of the whole organism.
Nucleus of the call is very small to be contain the DNA of cell. So DNA is present in the condense form by wrapping around the histones proteins which is known as cell division.
At the time of cell division, it is present in chromosomal form to equally divide the genetic material.
